Descriptiontext

Goldin Auctions, founded in 2012 by Ken Goldin, is an online auction house headquartered in Runnemede, New Jersey, that specializes in high-value collectibles including trading cards (sports, Pokémon, TCG), sports memorabilia, and entertainment collectibles. The company operates a proprietary e-commerce auction platform with professional authentication and grading verification services, handling transactions ranging from hundreds to millions of dollars, and has facilitated some of the largest collectible transactions on record, including the $16.49 million Pikachu Illustrator card sale in February 2026 and the $4.39 million Shohei Ohtani 50/50 home run ball in late 2024. In 2024, eBay acquired Goldin Auctions and integrated it through single sign-on capability and a 'Find It On Goldin' promotional carousel in eBay search results, materially expanding distribution.

Goldin earns revenue primarily through transaction-based commissions on successful auction sales, with an effective take rate of approximately 18% based on disclosed commission data from the Ohtani ball sale, supplemented by advance payments to high-profile sellers (e.g., $2.5M advance to Logan Paul against the Pikachu Illustrator card). Its primary customer segments are trading card collectors and investors, sports memorabilia sellers, and alternative asset investors seeking diversification away from public markets. The company serves a global market spanning North America, Europe, and Asia, with a marketing approach centered on the Netflix docuseries 'King of Collectibles: The Goldin Touch,' YouTube livestreams of high-profile consignor sales, and earned media coverage of record-setting transactions.
