Two Casascius physical Bitcoin coins containing approximately $2,000 worth of Bitcoin moved this week after remaining dormant for 13 years, according to Timechain Index founder Sani. Casascius produced physical Bitcoins that embed a real private key beneath a tamper-evident hologram; holders can redeem the coin’s Bitcoin on the blockchain by revealing the private key. The coins—among the earliest physical representations of Bitcoin—are considered rare collectibles, and any activity involving them draws attention from collectors and blockchain observers. Casascius coins sometimes become active after long periods of inactivity when owners decide to access or redeem the dormant holdings, sparking renewed interest in these historical artifacts that bridge Bitcoin’s early days and today’s market.
