What Is Weiss Auctions?

Weiss Auctions is a family-run auction house based in Lynbrook, New York that sells through periodic online catalog auctions covering sports cards, graded cards, and game-used and autographed memorabilia, often within broader multi-category sales rather than sports-only catalogs. It has run for decades under the same ownership, a longer track record than many newer online-only sports auction platforms.

• Periodic online catalog auctions— Weiss runs a schedule of multi-week catalog sales rather than a continuous fixed-price marketplace, the same general structure used by Heritage Auctions and Milestone Auctions.
• Cross-category catalogs— sports cards and memorabilia sales run alongside the house's other collectible categories, so the buyer pool for any given lot depends on which categories are featured in that sale.
• Consignment-driven— like most catalog houses, inventory comes from consignors rather than house-owned stock, so what's on offer varies from sale to sale.

Weiss has published a buyer's premium in the mid-teens percent range on top of the hammer price, plus applicable sales tax unless a valid resale certificate is on file — on the lower end compared with the roughly 20% rate charged at many larger sports auction houses, with a further discount typically offered for payment by cash, check, or wire instead of a card. Confirm the current buyer's premium, payment-method discounts, and seller commission terms before bidding or consigning, and see how sports card auction houses work for the fee mechanics that apply industry-wide.

• vs. Heritage Auctions — Heritage is a much larger multi-category house with sports as one of many dedicated collectible divisions. Weiss operates at a smaller scale with sports cards and memorabilia as one category among several in each catalog.
• vs. Milestone Auctions — both blend sports material with other collectible categories in a single catalog. Weiss's buyer's premium has run lower than the roughly 20% rate typical of the larger sports-focused houses.
• vs. Legendary Auctions — Legendary runs sports- and card-focused catalogs. Weiss's sales more regularly mix sports lots with other collectible categories, appealing to a broader buyer base per sale.

• Confirm the buyer's premium and payment discounts. Premium rates and payment-method discounts can change the total cost of a win; confirm both before placing a bid.
• Read lot descriptions and provenance closely. Game-used and autographed memorabilia carries authenticity risk that graded cards don't — check for third-party authentication (JSA, PSA/DNA, or similar) on autographed lots before bidding.
• Time consignments around the auction calendar. With periodic rather than continuous sales, plan a consignment around the next scheduled catalog close — see how sports card consignment works for the general consignment process.
• Verify vintage card condition independently. See how to spot a trimmed or altered sports card before bidding on ungraded vintage lots.
