Bidder Agreement
Version 2026-06-28. By placing a bid you agree to these terms.
Bidding is a binding obligation to pay
When you place a bid you agree to purchase the lot at your winning price if you are the high bidder at close. Bids cannot be retracted except at our discretion.
Buyer's premium and charges
A buyer's premium (a percentage of the hammer price, disclosed per sale) is added to every winning bid, along with insured, tracked shipping and any applicable tax. Your final total is computed at settlement once your shipping address is known.
Hidden reserve
A lot may carry a confidential reserve — the minimum price the seller will accept. You will only ever see whether the reserve is met or not met, never the reserve amount. A lot that ends below its reserve does not sell.
Payment window, second chance, and non-payment
Winning invoices are due within the stated payment window. If an invoice goes unpaid, the lot may be relisted or offered to the next-highest eligible bidder, and repeated non-payment may result in suspension.
Finality and the lifetime authenticity guarantee
Auction sales are final as to condition — there are no buyer's-remorse returns. Our lifetime authenticity guarantee is the deliberate exception: if any specimen is ever proven not genuine or not as described, it is refunded regardless of channel.
No-shill policy and fairness
The seller's accounts are barred from bidding, and every bid is server-authoritative, recorded in an immutable ledger, and screened for shill patterns. We describe our process as auditable and shill-screened.
Privacy and masking
Other bidders see you only as a stable per-lot pseudonym. Your real identity and your maximum (proxy) bid are never shown to anyone else.
Combined shipping
If you win multiple lots in a sale, they may be combined into a single invoice and a single, well-packed shipment, with any shipping overage refunded.
