Fact Check
All three independent sources converge on the same key facts: S1-COIN-25 designation, 25 BTC face value, Mike Caldwell's 2011-2013 Casascius mint, redemption on June 3, 2026, ~$1.78M value, and the tamper-evident hologram being peeled. Galaxy Research's X post provides on-chain verification (TXID 8fe6260a...a554, block 952159), and CoinDesk's article corroborates the mint timeline. The 'nearly 15 years' phrasing in the claim aligns with crypto.news; S1 series began in 2011, making the span ~14.7 years.

Summary

A 2011 S1-COIN-25 Casascius physical Bitcoin became active this week, with the 25 BTC tied to its long-dormant address moved in two transactions that shifted the funds into a SegWit address. Galaxy Research identified the item as a Casascius physical Bitcoin, and the original 25 BTC had been valued at about $1.78 million in the alert cited by the source. On-chain data shows the watched address received its 25 BTC output in block 156,413 on Dec. 7, 2011, later picked up small dust amounts, then spent 25.00002187 BTC on June 3 in block 952,159, returning 24.98998 BTC to the same address. A second transaction on June 4 in block 952,267 sent 24.98996629 BTC to bc1qn5snfwq447vge9ynnz66xqm9kpam9eu34z52dk with a fee of 1,371 sats, leaving the original address empty. The blockchain therefore shows a custody transition rather than a confirmed sale: bitcoin once tied to a physical collectible was made spendable and moved away from the original Casascius-attributed address, but there is no visible evidence yet of routing to an exchange, custodian or other liquidity venue.

Terms & Concepts
  • Casascius physical Bitcoin: An early physical Bitcoin collectible that holds bitcoin via a private key sealed inside the item.
  • SegWit address: A Bitcoin address format designed to improve transaction efficiency and reduce some transaction costs.
  • dust: Very small amounts of bitcoin left in or sent to an address, often too minor to matter on their own.
