Each coin came built with its own Bitcoin address, along with a private key that was hidden behind a tamper-evident hologram that must be peeled in order to reveal the key—letting the owner gain access to the linked BTC.
What started as a Bitcoin talking point ended up becoming a coveted collectible and vessel for considerable sums, given Bitcoin’s precipitous rise in the years since.
The latest redemption comes from the “Series 1” 25 Bitcoin batch, of which 345 coins in total were produced. At this time, 236 coins have been redeemed based on Casascius Tracker data, with this being the most recent redemption.
While coin redemptions have been steadily climbing over the years, the pace remains well below the end of 2017 and early 2018, when Bitcoin first rose near $20,000 for the first time.
Last October, when Bitcoin jumped to its all-time high of $126,080, 46 coins were redeemed with values ranging from 0.5-25 BTC, or about $3.15 million at the time for the top coin.
Last month, at least one 25 BTC coin was redeemed. Three other 25 BTC coins were cashed in at the end of April.
