Casascius Physical Bitcoin Redeemed, Unlocking Millions

A Casascius physical Bitcoin containing 25 BTC has been redeemed after nearly 15 years, unlocking cryptocurrency worth around $1.78 million. The coin, which was part of a 2011 Series 1 batch, is one of the latest in a series of long-dormant Bitcoin holdings to resurface as the cryptocurrency nears record valuations.

Created by Mike Caldwell, Casascius coins were among the earliest attempts to connect digital assets with physical collectibles. Each coin carried a Bitcoin address and private key concealed beneath a tamper-evident holographic seal, which could be removed to access the associated funds.

The redeemed coin's activation on June 3 highlights the remarkable appreciation of Bitcoin over the past decade and a half. The value of the 25 BTC contained in the coin has increased from less than $100 at the time of funding to nearly $1.78 million today.
