A physical bitcoin from the renowned Casascius mint, specifically the S1-COIN-25, was redeemed on Wednesday, resulting in the transfer of 25 BTC, valued at approximately $1.70 million. This event highlights the ongoing interest in physical cryptocurrencies and their unique status in the collectibles market.
Created by software engineer Mike Caldwell between 2011 and 2013, Casascius coins are tangible tokens that feature a printed bitcoin address on one side and a concealed private key under a tamper-evident hologram on the reverse. The recent redemption involved peeling off the hologram, a move that permanently removes the coin’s collectible value.
🪙 CASASCIUS COIN REDEEMED — S1-COIN-25 (25 BTC face) swept for 25.0000 BTC ($1.78M) A physical Casascius bitcoin from the 2011-2013 mint has been peeled and the private key swept on-chain.

Holders of these coins have the option to redeem their bitcoin by peeling the hologram and importing the private key into a digital wallet. However, this action effectively destroys the coin’s value as a collectible. Caldwell ceased production of these coins in late 2013 after receiving guidance from the U.S. Financial Crimes Enforcement Network, which indicated that he was operating as a money transmitter without the necessary license.
Despite the redemption of some coins, intact Casascius coins continue to be sought after in the collectibles market. These coins not only represent their face value in bitcoin but also command a premium due to their physical nature. Current estimates indicate that thousands of Casascius coins across various denominations remain unredeemed.
Among the rarest are the 1,000-BTC denomination coins, of which Caldwell minted fewer than 20. Most of these remain intact, potentially holding a value of around $66 million each at current bitcoin prices. While the Casascius project inspired other physical bitcoin mints such as Lealana and Denarium, it remains the most popular among collectors.
The recent redemption was recorded in Bitcoin block 952,159, coinciding with a period of unusual activity involving dormant wallets. Notably, a wallet from 2011 transferred 35 BTC after being inactive for 15 years.
In related news, Citi has commented on recent market fluctuations, indicating that a significant bitcoin sale by Strategy may have unsettled investors. However, they noted that the primary concern lies in the lack of demand from new buyers.
- Citi clarified that Strategy’s bitcoin sale was part of a previously disclosed tax-optimization strategy and does not impact their overall approach.
- The bank estimates that spot bitcoin ETF flows account for about 45% of weekly BTC price changes, serving as a key indicator of investor interest.
- Market sentiment is expected to remain cautious as these dynamics unfold.
The recent redemption of a Casascius bitcoin marks a noteworthy event in the world of cryptocurrency collectibles. As physical tokens continue to attract interest, the implications for both collectors and the broader market are significant.
