Rare 25‑BTC Casascius Coin Unsealed and 25 Bitcoin Swept On‑Chain

Peeling the tamper‑evident hologram destroyed the coin’s collectible value by exposing its private key.

Overview

  • The S1-COIN-25 Casascius 25‑BTC piece was unsealed and its 25 BTC were moved on‑chain in Bitcoin block 952,159 on Wednesday, June 3, 2026, according to blockchain records and tracker alerts.
  • On‑chain traces show a tiny network fee of about $2.79 and an initial test transfer of 0.01 BTC, which suggests the redeemer verified the revealed private key before completing further moves.
  • The person who peeled the hologram has not been publicly identified, and the redemption permanently voided the coin’s premium as a sealed collectible.
  • The coin came from the Series 1 batch of 25‑BTC pieces; Casascius Tracker shows 236 of 345 in that run have now been redeemed, reducing the pool of sealed, numismatic items.
  • The activation is part of a recent wave of long‑dormant early Bitcoin activity and highlights a recurring tradeoff between keeping Casascius coins as collectibles and converting them into liquid BTC after the mint stopped funding coins in late 2013 following FinCEN guidance.
