Selling
Prohibited Items
Last updated September 15, 2026 · Read the Auctioneer & Seller Terms
Check this list before you catalog a sale.
This list is part of the Auctioneer & Seller Terms (Sale Rule 2.4(f)). It says what may not be sold on Going Once, and what may be sold only in the way described. It applies to every lot, and to every item inside a lot, including a box of mixed items.
The list is not complete. Anything that is illegal to sell under California or federal law is not allowed, whether or not it is named here. If you are not sure about an item, ask us before you list it.
We may remove a lot that breaks these rules at any time, including while the sale is live. If it has already sold, we may cancel the sale of that lot and refund the buyer.
