Christie's is holding a live auction for a set of 31 Curio Cards and several other notable non-fungible token (NFT) initiatives. In March, the auction house made history by auctioning a Beeple NFT for $69 million. Christie's live bidding will be denominated in cryptocurrency rather than normal local currency for the first time on Oct. 1. Christie's will auction a set of Curio Cards from Art Blocks Curated series, consisting of three full sets of 31 NFTs.
