How to bid with Baldwin's

BIDDING AT OUR AUCTIONS couldn't be easier and we offer a variety of methods to all our customers. If you are at all unsure about how to bid with us then please call or email us and one of our auction team will be on hand to help you.

Bidding in person

Admission to the auction room and participation is free once you have a copy of the catalogue which will be available at no cost if you attend the auction in person. To bid in person at any of our sales (both in the UK and internationally) you will need to register for a bidding number; members of our team will be on hand at the registration table outside the auction room to take your details and provide you with a bidding number. Please ensure that you arrive in plenty of time for the lots you are interested in as it may take a few minutes for our staff members to take your registration details. A time guide is printed at the front of this catalogue to help you with this and approximately 200 lots are sold per hour. Bidders are reminded that this is a guide only and Baldwin's cannot be held responsible if you miss your lot.

Participants should supply their highest bid for each lot and lots will be purchased as cheaply as possible on their behalf against all competition. Absentee bidders will not be contacted prior to the auction if their top bid has been exceeded. Bidding begins below the low estimate and if yours is the only bid you will win the lot for the opening price no matter what your top bid may be. In the event of identical absentee bids, the earliest bid we receive will take priority.

Please be aware that Baldwin's will not sell any lot at less than 80% of the low estimate and this should be taken into consideration when you are leaving an absentee bid.

Full colour catalogues for all of our auctions are available with majority of the lots fully illustrated (both obverse and reverse). Great care is taken to produce the highest quality images of the lots and Baldwin's take pride in the quality of the representations contained in the catalogue. The full catalogue can also be viewed online on our own website and at and images contained herewith can be expanded using the zoom facility.

The catalogue is printed with estimates alongside each lot and the estimate is intended as a price guide for interested bidders. Although it is our opinion of the value of the lot bidders should be clear in their own minds what each lot is worth and should be prepared for prices to rise if there is competition for the lot. All lots can realise hammer prices both above and below the printed pre-sale estimate. Please note in normal circumstances, each lot is reserved at 80% of the lower estimate and bids below this are very unlikely to be accepted.


You are encouraged to view the lots before the sale and attend the auction in person if you can.
