How our auctions work
Bid with a maximum
Set your ceiling and we bid for you only as far as needed. A sole bidder pays the opening price.
Increments apply
Each lot shows its minimum step. Bids below the current bid plus the increment are rejected.
No last-second wins
A bid inside the closing window extends the lot, so everyone gets a fair chance to respond.
Settlement by invoice
Winners are emailed after the hammer with settlement and shipping details.
