A Casascius physical Bitcoin loaded with 25 BTC — worth roughly $1.78 million at the time — was redeemed this week, breaking more than 14 years of silence. The coin, a Series 1 brass token (S1-COIN-25), originally received its balance on December 7, 2011, in block 156,413. That stash stayed untouched until June 3, 2026, when a transaction in block 952,159 finally moved it.
The two-step redemption
The owner didn't just send the whole 25 BTC in one shot. On June 3, a transaction spent 25.00002187 BTC, returning 24.98998 BTC to the same address after fees and a small dust handling. The next day, block 952,267 saw the remaining 24.98996629 BTC transferred to a SegWit address: bc1qn5snfwq447vge9ynnz66xqm9kpam9eu34z52dk. A 1,371 satoshi fee covered the move. By the end, the original address held zero balance.
Casascius coins aren't like regular Bitcoin keys. They ship with the private key sealed under a tamper-evident hologram. To spend the BTC, you have to break that seal — destroying the physical collectible in the process. The choice is binary: keep the numismatic item or turn it into liquid crypto. This redemption traded a piece of Bitcoin history for blockchain spendability.
No sale — yet
The destination address isn't linked to any known exchange deposit, custodian routing, or repayment activity. The movement looks like a custody transition: the owner likely moved the funds into a SegWit wallet they control, rather than selling into the current market selloff. That doesn't rule out a future sale, but there's no evidence of one so far.
A rare artifact from Bitcoin's infancy
Casascius coins were minted by Mike Caldwell starting in 2011. Each contained a fixed amount of BTC at the time of creation, and the series became a collector's holy grail. Many were never redeemed — their owners either lost the keys or kept them as relics. Activating one now is rare. The timing, during a market downturn, adds a layer of intrigue, but the owner may simply have wanted to secure the funds in a software wallet without relying on a physical object.
The SegWit address bc1qn5snfwq447vge9ynnz66xqm9kpam9eu34z52dk now holds 24.99 BTC. Whether that turns into a market order or sits untouched remains the next open question. What's certain is that one more Casascius coin has left the physical world for good.
