How to check a certificate
Step 1
Find the badge
Authenticated lots carry a badge on their photo with the authenticator and any grade.
Step 2
Open the certificate
The Authentication section of the lot page shows the certificate number, a photo of the certificate where we have one, and a Verify button that opens the authenticator's own record.
Step 3
Compare
Check that the record matches the item in our photos. If anything doesn't look right, tell us before you bid.
Fair bidding
No sniping
A bid in the last 3 minutes adds 3 minutes, so the last word is never a surprise.
Private maximums
Your maximum bid is yours alone. In the bid history other bidders appear as Bidder 1, Bidder 2, and you as You.
Honest money
You pay the winning price plus shipping, packaging and sales tax. There's no buyer's premium. Invoices are paid online with PayPal, so your card or bank details never reach our site. Consignors pay our 17% commission out of their sale, and are paid after the buyer has paid.
Your details
We only use your details to run your account, your bids and your orders. Your email address and shipping address are never shown to other bidders. Read our privacy policy.
