DALLAS, TX.- Heritage Auctions’ inaugural Sports Monthly Showcase Auction realized $3.3 million upon closing early Friday morning. This sale was the first of its kind in the nearly 20-year history of Heritage Auctions’ Sports Category — fewer than 400 lots in a sale that featured only material already graded and/or authenticated by a leading third-party service when consigned. It ran for two weeks, from opening to extended bidding, to better shrink the window between consignment, auction and payment. And unlike most of Heritage’s sports auctions, it was done without a catalog.
