According to Stack's Bowers Galleries, the auction house is auctioning a funded 0.5 Bitcoin Casascius token graded MS-66 on June 18. Only 15 examples exist at that grade, with just 11 coins graded finer at MS-67. The physical token, minted by Utah-based engineer Mike Caldwell in 2011, retains the original 0.5 BTC loaded onchain and remains redeemable.
The June 18 sale features over 120 crypto collectibles with combined intrinsic value exceeding $500,000, including coins from the Casascius, BTCC, and Lealana series, alongside Topps Allen and Ginter crypto trading cards and early Bitcoin Magazine issues.
