Auction Buying FAQ

Leonard Auction offers a fully illustrated online catalog that is constantly updated before each auction.

Leonard Auction provides an opinion of the condition of each lot that is stated in a Condition Report. These statements are available on the online catalog and printouts available at the auction house. While we make every effort to accurately describe items, please note that items are Sold As-Is, Where-Is with all faults.

New bidders will need a driver’s license or state ID to register for the auction. We reserve the right to require credit prior to registration.

As a general rule, Leonard Auction will open the bidding at 1/2 the low estimate. In some select cases bidding may open lower and in many cases bidding will open higher depending on pre-auction bidding activity.

If there is no pre-auction bidding activity, the absentee bid will open at 1/2 of the low estimate. If we have pre-auction bidding activity, the absentee bid will open at one bid above the highest pre-auction bid.

No, all auction sales are final and we do not accept returns. We are happy to re-offer an item purchased from auction for a reduced commission provided the item was purchased for $300 or more.
