This week, a rare physical bitcoin, known as the S1-COIN-25, was redeemed for its full value of 25 BTC, approximately $1.78 million. The coin, part of a limited series minted by software engineer Mike Caldwell between 2011 and 2013, had its tamper-evident hologram removed, which destroyed its collectible status. Casascius coins are notable for embedding real bitcoin and are highly sought after by collectors, often fetching a premium when left intact. Caldwell halted production of these coins in late 2013 after regulatory advice indicated he was operating as a money transmitter without a license. The redemption of this coin comes amidst a broader wave of activity from previously dormant bitcoin wallets, including a notable transaction of 35 BTC from a wallet that had been inactive for 15 years. Despite the redemption, thousands of Casascius coins remain unredeemed, with some large-denomination coins potentially holding significant value. This trend reflects a growing interest in previously untouched bitcoin assets.
