The hidden fragment of cryptohistory has found new life: an anonymous collector extinguished the physical coin Casascius of the first series with a value of 25 BTC, which remained untouched for more than a decade. Galaxy Research tracked the transaction initiated after the holder removed the protective hologram, retrieved a hidden private key, and transferred funds to the new address. At the time of minting this coin, the bitcoin was worth less than $100; today, the equivalent is estimated to be about $1.83 million.

Out of 345 Casascius specimens with a nominal value of 25 BTC, this activation reduces the number of samples still outstanding to less than 108. Galaxy Research experts noted: the violation of the hologram’s integrity, which opened up access to cryptocurrency, simultaneously destroyed the numismatic premium of the artifact – an additional cost that enthusiasts are willing to pay for historical significance and perfect preservation, – reaching tens of thousands of dollars. By opting for liquidity, the owner knowingly abandoned the collectible potential.

These iconic physical tokens were created by developer Mike Caldwell between 2011 and 2013; the denominations ranged from 0.5 to 1000 BTC. On the face of each coin was placed a public address for replenishment, while the private key was hidden under a hologram with protection against opening on the reverse. Production was completed in late 2013 after Caldwell received a notification from FinCEN that it might be subject to cash transfer licensing requirements. This activation followed an independent oncheen event captured by the Arkham platform: a wallet created in the first year of Bitcoin, moved 2,650 BTC – about $203 million at current rates – to over-the-counter trading platforms FalconX and Cumberland.
