A rare Casascius physical Bitcoin, valued at $1.78 million, has been activated after 12 years of dormancy.

CoinFeed reported on June 4th that, according to CoinDesk, a rare Casascius physical Bitcoin from 2011-2013 was activated on Wednesday. Its holographic security tag was removed, and the 25 BTC (worth approximately $1.78 million) stored within were transferred to a new wallet. Casascius coins, created by software engineer Mike Caldwell, came in denominations of 0.5, 1, 5, 10, 25, 100, and even 1000 BTC. Each coin had a receiving address printed on the front, while the private key was hidden under a holographic security tag on the back. Holders could remove the tag at any time to import the private key and use the Bitcoin, but this would diminish the coin's collectible value. Caldwell ceased production in late 2013 after being informed by the U.S. Financial Crimes Enforcement Network that he was operating an unlicensed money transfer business.
