Christie's

Christie's is an Auction-House-tier channel, the British fine-art auctioneer founded in 1766 by James Christie and the oldest of its kind, owned by Groupe Artemis. It is an auction house, not a forensic authentication bureau: its assurance for a piece rests on catalogue records, provenance research and lot history rather than a certificate it issues as an authenticator, and since 2018 it has offered blockchain-based ownership records for selected lots that give a transparent, durable provenance trail.

Why this matters for collectors

For a collector, Christie's value is the depth of its provenance record: a lot sold through Christie's carries its catalogue description, documented ownership history and, for some pieces, a blockchain ownership certificate, backed by more than two centuries as the oldest fine-art auction house. The assurance is the auction provenance, not a signature opinion from an in-house bureau, so a Christie's-routed item is best held with its catalogue and lot documentation. Christie's does not operate a certificate-lookup database for signatures, so where a piece is independently authenticated the verification route is that third party's certificate. Walkouts references Christie's as an auction channel whose assurance is documented auction-house provenance.
