Bitcoin might be the world’s most prized coin as of 2025 — but good luck flipping it, holding it, or tossing it into a fountain for luck. That’s because, unlike traditional currency, Bitcoin generally exists purely as a digital asset. Yet there’s an intriguing exception: physical Bitcoins. These tangible tokens blend digital crypto value with collectible appeal. This guide explores what a physical Bitcoin is, how it stores real Bitcoin, and — most importantly — what a physical Bitcoin is actually worth.
KEY TAKEAWAYS ➤ A physical Bitcoin is an object such as a coins or a tokens, with a digital value.objects such as coins or tokens, whose value is digital. ➤ Usually, it is a metal coin imprinted with the information necessary for the holder to access BTC the Bitcoin blockchain. ➤ Casascius coins, issued by Mike Caldwell between 2011-2013, were the most famous physical Bitcoins. The metal tokens were funded with BTC and sealed with holograms.
A physical Bitcoin is a tangible item — typically a coin or card — that holds access to Bitcoin through a hidden private key. Unlike symbolic souvenirs, genuine physical Bitcoins store real BTC value on-chain.
The most well-known example, Casascius coins, appeared in 2011 and included a sealed private key beneath a tamper-evident hologram. Owners could verify the balance using the public address engraved on the coin.
Physical Bitcoins function as cold storage tools while also holding collector value due to their rarity and historical relevance. After regulators intervened in 2013, funded physical coins became harder to produce legally.
As a result, intact originals are now rare and often sell at prices well above their BTC content. A physical Bitcoin combines crypto security with real-world scarcity, thereby making itself both practical and collectible.
People search for physical Bitcoins out of curiosity and for practical reasons like collecting, investing, security, gifting, and novelty.
Many are intrigued by the idea of holding Bitcoin in hand since Bitcoin, by design, is entirely digital. This curiosity drives people to look up physical coins or devices representing BTC.
Collectors and investors see physical Bitcoins (especially limited editions) as rare assets that could appreciate in value. Others seek them for security — a funded physical Bitcoin can act as a cold wallet kept offline, safe from hackers.
Gifting is another motive: a physical coin or paper wallet can be a memorable way to give someone Bitcoin. In short, people want physical Bitcoins either to own a piece of crypto history or to use them as a handy, touchable form of cryptocurrency.
Physical Bitcoin history began in 2011 when hobbyists started minting coins and cards loaded with digital BTC — most famously Mike Caldwell’s Casascius coins.
The concept of physical Bitcoin emerged early in Bitcoin’s timeline. In May 2011, a project called BitBills launched the first physical Bitcoins as small plastic cards. Each BitBill card had a Bitcoin private key embedded inside and protected by a tamper-evident hologram, with denominations from 1 BTC up to 20 BTC.
Note that at the time, Bitcoin’s price was still in its infancy. It started 2011 at just $0.29, crossed $1 for the first time in February, and peaked at a modest $26 in June.
BitBills were meant to be passed hand-to-hand like cash, and once opened to reveal the key, they were “spent” and couldn’t be used again. This innovative idea introduced the notion of a “bearer instrument” for Bitcoin — whoever holds the object can redeem the digital value.
BitBills ceased production by May 2012, but they paved the way for more popular physical Bitcoins.
Casascius coins were the first widely-recognized physical Bitcoins: metal tokens funded with real BTC and sealed with holograms. It was issued by Mike Caldwell from 2011 to 2013.
For those out of the loop, Mike Caldwell is a Utah-based software engineer with a background in cryptography and systems design. He became one of the early figures in Bitcoin’s history by exploring ways to make the digital currency more tangible and user-friendly.
Each Casascius coin contained an embedded private key printed on a piece of paper and encased inside underneath a custom tamper-evident holographic seal. The public Bitcoin address was often engraved or printed on the outside, so anyone could verify the balance on the blockchain while the coin remained sealed.
If the hologram was intact, it assured that the private key hadn’t been revealed or used. Peeling off the hologram would irreversibly show a honeycomb pattern to indicate tampering.
Caldwell’s Casascius coins quickly became iconic. Between 2011 and 2013, he minted nearly 28,000 funded coins of different values. Almost 90,000 BTC were loaded into Casascius physical Bitcoins in total.

These coins were sold online (paid in BTC) and even given out by Caldwell as gifts to help spread Bitcoin adoption. Casascius coins turned Bitcoin into something you could hold and trade in person, and they are regarded as a piece of crypto history.
In late 2013, Mike Caldwell had to abruptly suspend Casascius coin sales. The U.S. Financial Crimes Enforcement Network (FinCEN) informed him that minting loaded physical Bitcoins qualified as money transmission, which would require him to register and comply with money transmitter laws.
Essentially, regulators saw Casascius coins as a form of private currency creation. Rather than fight a legal battle, Caldwell stopped making loaded coins on November 27, 2013.
This government intervention ended the Casascius series and made the existing supply limited. Roughly 18,000 Casascius coins remain intact (unredeemed) today, since many have been peeled open over time.
As more get redeemed, the remaining supply becomes even rarer and more valuable to collectors. Casascius coin set the template for physical Bitcoins and its story illustrates the clash between crypto innovation and financial regulation.
After Casascius, other enthusiasts and companies issued their own physical Bitcoins, including alternative coins and innovative designs.
Even before Casascius ended, others were experimenting with physical crypto tokens:
A series of physical Bitcoins and Litecoins created by a user known as “Smoothie” (real name Noah Luis) around 2013–2014. Lealana coins were similar to Casascius (metal coins with holograms) but often buyer-funded — the purchaser would load the coin with BTC themselves, which helped bypass certain regulatory limitations.
Lealana offered coins in fractions like 0.1 BTC and also produced physical Litecoin tokens. They are also highly collectible today, though produced in smaller quantities than Casascius.

Alitin Mint (launched in 2014) produced a few high-end physical Bitcoins that doubled as commemorative coins featuring historical figures. For example, one Alitin coin series depicted economist Adam Smith and was loaded with a certain BTC amount.
These coins were made of precious metals. However, Alitin Mint’s project was short-lived; in 2017, a security breach reportedly compromised their private keys, leading to a shutdown of the operation. This incident highlighted the risk of a manufacturer’s key generation system being hacked.
Titan Bitcoin (2014) created physical coins with a twist: each coin had a unique QR code and a verification phone number. Owners could call or check online using the coin’s ID to verify the loaded amount.
The private key was hidden under a hologram, similar to Casascius. Titans were marketed as high-security physical Bitcoins with anti-counterfeit measures. Titan issued various denominations (e.g., 0.5 BTC, 1 BTC). The company ceased operations after a few years, but Titan coins can occasionally be found secondhand.
One of Bitcoin’s largest exchanges, BTCC (run by Bobby Lee) issued a series of physical Bitcoin coins for a couple of years. These coins, often denominated in smaller amounts like 0.1 BTC, had elaborate designs and came with certificates. They served as collectibles and a promotional tool.
BTCC’s coins were funded and sealed similarly with holograms. Production stopped when the exchange closed in 2018.
Finnish company Denarium created “low-cost” physical Bitcoins. It made brass coins that could be bought empty or pre-loaded with small amounts (like 0.01, 0.1 BTC). Some Denarium coins allowed the buyer to choose how much BTC to load (Custom Series). By selling coins that users fund themselves, Denarium reduced regulatory concerns.
These coins also used holograms to cover the key, and thousands were sold worldwide. The company concluded its coin programs around 2018–2019.
| Type | Era | Format | Security level | Ease of use | Collector value | Typical resale price |
| BitBills Card | Early (2011) | Plastic card, printed key | Moderate – tamper-evident hologram; maker knows key | Simple: scan or peel to use | Very high (first physical BTC, rare) | Hard to find; can fetch tens of thousands if loaded (extremely scarce) |
| Casascius Coin | Early (2011-13) | Brass (some silver/gold), coin with hologram | High – strong hologram seal; key generated by maker | Very easy: verify balance online, peel to redeem | Extremely high (iconic, limited run) | Often above BTC face value (e.g. a 1 BTC coin sells for more than 1 BTC), high-denomination coins worth millions if intact |
| Lealana Coin | Early (2013-15) | Metal coin with hologram | High – hologram seal; some were buyer-funded (safer) | Easy: similar to Casascius | High (limited series, crypto history) | Varies – typically premium over BTC if loaded; e.g. 0.1 BTC coin can sell for thousands in graded condition |
| Paper Wallet | Early and ongoing | Paper printout or certificate | Variable – as secure as the offline generation and storage method | Moderate: requires importing software to spend | Low as collectible (common method, not artwork) | No premium – value equals the BTC loaded (novel designs might sell for a bit more) |
| Denarium Coin | Modern (2015-18) | Brass coin with a hologram | High–trusted maker, user could fund (reducing trust issue) | Easy: funded by user or pre-loaded, peel to use | Moderate (newer, higher mintage) | Small premium if loaded (e.g., 0.1 BTC coin might sell for slightly above 0.1 BTC) |
| Ballet Wallet | Modern (2019+) | Steel card (non-electronic) | High – 2-factor key (private key encrypted with passphrase); manufacturer never has full key | Very easy: no setup, just send/scan funds | Low (widely available, utilitarian) | Resale at face value or slight markup (mostly valued for loaded crypto itself) |
| Opendime | Modern (2016+) | USB stick device | Very high – user-generated key inside device; tamper must be physical break | Moderate: needs computer to check balance; easy hand-off | Low (not a display item, mass-produced) | Resale equals loaded BTC value + small device cost (device itself ~$15) |
| Novelty Coins (unloaded) | Ongoing | Metal souvenir coins (no BTC) | N/A – no private key (just decorative) | N/A – cannot store value | Minimal (unless rare design/limited) | Very cheap (a few dollars each); some limited collectibles might resell for $10-$100 |
Physical Bitcoins work by storing the coin’s secret private key in a physical object and keeping it hidden and secure until someone decides to redeem the value.
Every Bitcoin address has two key components: a public key/address (which you share to receive BTC) and a private key (which you must keep secret, as it allows spending of the BTC).
A physical Bitcoin, in essence, is a physical bearer instrument that contains the private key. The creator of a physical Bitcoin will generate a new Bitcoin private key and load a certain amount of BTC to its corresponding public address on the blockchain.
Then they embed that private key into a tangible item — whether by printing it on paper, embedding it in a chip, or sealing it under a hologram on a metal coin.
The physical item is engineered so that the private key remains concealed and secure. For coins like Casascius, the key is printed on a tiny piece of paper inside the coin, and a holographic sticker covers the slot; you cannot access the key without irreversibly damaging the seal.
For devices like Opendime, the key is locked inside the hardware and only becomes accessible if you physically break the device. In all cases, the first person to uncover the private key can sweep (spend) the Bitcoin associated with it. Once that happens, the physical token is considered “spent” or redeemed since the BTC moves out of the address.
You can’t (typically) reload the same physical Bitcoin with new BTC after it’s been redeemed. For instance, once a Casascius coin’s hologram is peeled and its funds spent, the coin is just a collectible piece of metal with no monetary value on the blockchain anymore.
The best way to use a physical Bitcoin is to verify and trust, then redeem. Here’s how you do it:
First, confirm its authenticity and the funded amount before purchase. Check and make sure the hologram or other verifiable element is intact (no tampering or resealing signs).
Also, use the visible public address or serial number to look up the balance on a blockchain explorer. Legitimate physical Bitcoins will have a known address that shows the expected BTC balance.
If the blockchain shows 0 BTC or a lower amount than advertised, the coin might have been redeemed or be a scam. If all looks good, you can treat the coin as holding that value.
You can then hold onto the physical Bitcoin, trade it, or give it to someone. As long as the private key stays hidden, it’s like holding a cash note — bearer ownership.
Do keep it safe from loss or theft (since whoever has it could peel and spend it).
When you decide to spend or move the Bitcoin, you (or the current holder) will open up the physical Bitcoin. This might mean peeling off the hologram sticker (coins/cards), scratching off a cover, or breaking a device seal.
The private key (often in the form of a string of letters/numbers or a QR code) will be revealed. You then import or scan that private key into a Bitcoin wallet to sweep the funds into a new address you control.
Sweeping means you create a regular Bitcoin transaction sending all the BTC from the physical coin’s address to another address (like your mobile wallet). After this, the physical coin’s original address will be empty, and thus the physical Bitcoin is “cashed out.”
It can’t be reused to hold value unless you somehow reassemble and re-seal it with a new key (generally not practical).
Important: If you do redeem a physical Bitcoin, be mindful of privacy. Redeeming links the coin’s address to a new address you use, which could deanonymize a previously untraceable physical exchange.
A physical Bitcoin’s value comes from two parts. First, the Bitcoin it contains (if any), and then the collectible or novelty value of the item itself. These factors combined determine how much a physical Bitcoin is worth.
If a physical Bitcoin is loaded with real BTC, its baseline value is the amount of Bitcoin it carries at the current market price.
For instance, a physical coin with 1 BTC loaded is worth 1 BTC — if Bitcoin trades at $100,000, that coin’s base value is $100,000. This assumes the coin’s private key is still secure (hologram intact) and the BTC is unspent.

The market price will fluctuate, so on a different day that 1 BTC could be worth $105,000 or $95,000, and the physical coin’s intrinsic value moves accordingly.
However, many physical Bitcoins also have numismatic and collector premiums. A coin’s rarity, age, brand, and condition can make it worth significantly more than the crypto it holds.
For instance, an intact 1 BTC Casascius coin from 2011 not only has 1 BTC inside, but is also a piece of Bitcoin history — collectors might pay a premium above the 1 BTC for that nostalgia and scarcity.
In November 2024, a 2011 Casascius 1 BTC brass coin graded MS66 by NGC sold for $84,000 at a Heritage Auctions event. Interestingly, Bitcoin was trading around $70,000 at the time, showing the buyer paid a ~$14k premium for its collectible value.
Similarly, early series Casascius coins, especially ones graded in perfect condition, have fetched large premiums. Peeled or spent coins (with no BTC) can still hold high collectible value if they are rare editions.
For example, in June 2023, Stack’s Bowers Galleries auctioned a redeemed 2011 Casascius “Bearer” Bitcoin storage bar for $4,320.
On the other hand, a run-of-the-mill unfunded novelty coin with a Bitcoin logo (mass-produced and sold as a souvenir) might only be worth $5–10, mainly for its craftsmanship or material.
In practical terms, common physical Bitcoins (like a 1 BTC Casascius coin or a 0.5 BTC Denarium) tend to be listed at least 10-50% above their BTC content if intact. Truly rare pieces (e.g., earliest series or high denomination Casascius) can be multiples of their BTC value.
You can buy or sell physical Bitcoins through online marketplaces, collector forums, auction houses, or private sales. Each option has its pros and cons, and caution is essential, especially when dealing with loaded coins.
Platforms like eBay list everything from cheap novelty coins to high-value graded Casascius coins. Some may still hold BTC, but many are either redeemed or replicas. Always check seller ratings, hologram integrity, and whether the coin has been graded by a third party.
Communities like Bitcointalk host physical Bitcoin trades. Trusted members often use escrow, and rare items sometimes show up here at better prices. You will need to build trust and do your research.
Mainstream auctioneers now handle physical Bitcoins alongside rare coins. Coins sold here are usually authenticated and graded, which gives buyers more confidence. High demand often drives sale prices well above BTC value.
High-end items may be sold directly between collectors or via niche dealers. These transactions typically rely on trust or third-party verification.
Take these key precautions before you buy a physical Bitcoin: ➤ Verify the coin by checking its public address for BTC balance and authenticity. ➤ Use escrow services for large trades, especially in peer-to-peer deals. ➤ Follow legal requirements for high-value coins, including customs declarations. ➤ Understand platform rules—some don’t allow direct BTC sales but permit collectibles.
Physical Bitcoins exist at the intersection of crypto utility and collector curiosity; part digital wallet, part historical artifact. As explained in this guide, their value depends on both the BTC they hold and the rarity of the object itself. Ultimately, they are usually of most interest to collectors and die-hard crypto fans. If you are considering buying, selling, or redeeming physical Bitcoins, ensure to do your due diligence, be aware of the risks and associated scams, and never invest more than you can afford to lose.

A physical Bitcoin is not Bitcoin itself — it’s a container holding a private key that controls real BTC. If the key is intact and loaded, the item effectively holds Bitcoin. If it’s a decorative coin without a key or balance, it’s only symbolic.
Check if the coin has a public Bitcoin address and enter it into a blockchain explorer to verify the BTC balance. Multiply the balance by the current Bitcoin price for its base value. Then review recent auction sales or listings to assess its collector premium.
Expose the private key by peeling off a hologram or opening the device. Import or sweep the key into a digital wallet to transfer the BTC. Once redeemed, the coin’s value as a secure holder is gone.
Yes, you can send more BTC to its public address if you trust the private key’s security. However, if you didn’t create the key, reloading is risky. It’s better to use a fresh wallet for storing additional funds.
Most gold-tone Bitcoin coins online are just novelty items with no real BTC or key inside. They’re decorative souvenirs and hold no crypto value. So, always make sure to confirm if a coin is funded before assuming it’s an investment.
About 27,938 Casascius coins and bars were created from 2011 to 2013. They held around 91,000 BTC in total. Many have since been redeemed, with fewer than 20,000 believed to remain unspent.
Physical Bitcoins are one-time-use items meant for gifting or collecting, usually with a fixed BTC amount. Hardware wallets like Ledger or Trezor are reusable, secure devices for managing keys and making transactions. The former is designed for handing over BTC, while the latter is for long-term digital management.
Yes, you can create one, but there are legal and trust risks. Selling funded coins could involve financial regulations, and buyers may not trust that you didn’t keep the key. Selling unfunded coins avoids legal concerns and builds trust more easily.
The Casascius 1,000 BTC gold bar is the most valuable, worth tens of millions. High-grade 25 BTC and 100 BTC coins have also sold for hundreds of thousands. Collectors pay premiums based on rarity, metal content, and grading.
