What is a Mail Auction?

       A mail auction is an auction where all items are presented in a catalog and bids are sent in by mail. The bids are accepted up until a stated cut-off time. All bids are opened at a designated time with the highest bidder above the estimate, winning the item.

     Open Bid Auctions permit the bids to be opened as they arrive and share the high bids with other bidders.

     Sealed Bids are opened at a prescribed time and the highest qualified bidder wins. Bidders in this type of auction must provide their highest bid.

Harmers will only use Mail Auctions for Sealed Bids in special circumstances

      We will only use mail auctions when the seller is compelled by law or court order to sell the material in that fashion.


     Our website will contain information on the Mail Auctions, when they are offered or sign-up for our e-mail newsletter to be kept up to date on Harmer’s activities.
