What is a Bitcoin Casascius?
A Bitcoin Casascius is a physical collectible item, usually made form silver or gold. The item was created by Mike Caldwell, a Utah based entrepreneur, back in 2011.
According to the Casascius Bitcoin Analyzer website, the collectibles were sold as coins or bars. Coins carried as low as 0.1 BTC to 1,000 BTC, while bars had a minimum of 100 BTC up to 1,000 BTC per bar.
Each Casascius worked as a Bitcoin cold storage device. Each physical coin and bar had a public Bitcoin address. Inside the coin or bar, there’s a redeemable private key, protected by a tamper-evident hologram.
Once the hologram is removed, it leaves a honeycomb pattern as proof of access. Some Casascius are advanced and have an encrypted private key. Owners of such collectibles must decrypt the private keys using a passphrase to redeem the bitcoins.
Caldwell sold 27,912 Casascius coins and bars, funded with digital bitcoins. The items contain a total of 98,483.9 BTC.
In late 2013, Caldwell stopped selling physical coins and bars that contained digital bitcoins. At the time, US FinCEN (Financial Crimes Enforcement Network) said he was acting as an unregistered money transmitter.
According to a post from X user Sani, a total of 17,835 BTC Casascius remain unopened. They carry 36,467 bitcoins worth $3.29 billion.

In the past hour, 7 BTC moved for the first time in over a decade across four transactions.
