In the saleroom

In order to be able to place a bid in the sale room during the auction a bid number is required. Prior to the auction a bid number will be allocated to you after registration at the reception desk. When registering, your personal details and ID will be recorded and checked. The bidding takes place by hand signals after the auctioneer has announced a lot.

Absentee bid (online)

Another possibility is to leave a written bid via the online catalogue on this website. To do this, you must first register and then log in here at the top right. After completing the registration of your account, you are able to place a maximum written bid in the catalogue for the relevant lot. Please note: written bids are accepted up to one hour before the start of the auction. The auctioneer will bid on your behalf and will try to acquire the piece at the lowest possible price with a maximum of the amount indicated by you. You will receive a confirmation e-mail of the bid and can review it in your online account under my online absentee bids.

Absentee bid (bid form)

In addition to the online absentee bid option, you can also use the bid form printed in the catalogue or by downloading it here. When submitting your bid form, please make sure to send it by e-mail or fax and not by post.

By phone

We invite you by telephone. You will be called during the auction by an employee of the auction house on a telephone number specified by you. This option will allow you to follow the auction of a particular lot and bid via the assigned employee who will bid on your behalf in the sale room. Please inform our team regarding your wish to bid by telephone up to two hours prior to the auction and make sure you are easily reachable.

Live online (via Invaluable)

Finally, you can also participate in the auction live on the internet via Invaluable. You must register with Invaluable at least two hours before the start of the auction via the link below. After the registration you can follow the auction via the internet and participate directly as a bidder. It is also possible to leave a written bid via Invaluable

Please note: for live bidding on Invaluable via this link, an extra fee of 2% ex VAT will be charged on the hammer price. However, if you bid via the Invaluable website itself, that is 5% ex VAT, therefore we advise you to use our direct link.

You can also watch the auction live online on Invaluable free of charge and without registration. Of course, no additional costs will be charged for bidding directly through us; either as a written bid or telephone bid.


For unsold objects, there is the possibility of the after-sale. After the auction, a selection of these objects will be shown on the aft-sale page for a period of three weeks. During this period it is possible to place a bid: online, by e-mail or telephone. Your bid is only valid after you have received a confirmation from the auction house. In case more than one bidder is interested in the same lot, a new bid procedure has started, in which the highest bid counts.
