Heritage Auctions

Heritage Auctions, headquartered in Dallas, is the world's largest collectibles auction house and the dominant venue for high-end vintage comic books and original comic art. Their Comics & Comic Art department runs major Signature Auctions several times a year, alongside weekly Sunday Internet Comics Auctions and standalone Showcase events for premium consignments.

For collectors and dealers researching market values, Heritage's free public archive is one of the most valuable tools on the internet — every lot ever sold is permanently searchable with photographs, condition notes, certification numbers, and the actual realised hammer price plus buyer's premium. This makes it the de-facto comp source for graded keys, pedigreed copies, original art, and historically significant lots.

Heritage's bidding platform supports proxy bidding, live signature auctions, and private treaty sales. They also act as a consignment partner for sellers with high-value books — fees vary by lot and category, but consignors benefit from Heritage's enormous global buyer base and the marketing reach of their printed and online catalogues.

If you are tracking a specific key issue or original art piece, set up a saved search on Heritage to be notified when fresh examples come up. Their Comics Reference Library and grading-population data are also useful free resources for any serious collector.
