Frequently Asked Questions


How do I bid?
  • To place your bid, please create an account on Invaluable and register as a bidder for our auction. You can leave bids from the moment the auction catalogue is online until the scheduled end time for every lot. You will be notified by email if you are outbid.
  • To avoid auction rush, you may prefer to enter the maximum amount you are willing to bid at once. Then the system will bid for you till this limit is reached, winning the lot at the lowest price necessary to beat your competitors. This maximum amount is visible to no one but you. Lots that see bidding activity in the last five minutes before shutting down will be automatically extended for another five minutes; this ensures a fair auction for everyone. Please note that our auctions are online only.
  • Bids are raised by fixed increments. Up to €100 the increment is €5, from €100 to €200 the increment is €10, from €200 to €300 the increment is €20, from €300 to €500 the increment is €25, from €500 to €1.000 the increment is €50, from €1.000 to €2.000 the increment is €100, from €2.000 to €5.000 the increment is €200, from €5.000 to €10.000 the increment is €500, and from €10.000 upwards the increment is €1.000.
How much is the buyer’s premium?

Winning bidders pay a buyer’s premium of 24.2% over the hammer price including all taxes, plus the 3% online transaction fee charged by Invaluable.

Can I bid by telephone?

Since our auctions are online only, bidding by phone is unnecessary. The 3% fee for Invaluable is charged over all hammer prices, including for the lots we win on behalf of our clients. Therefore, there is no advantage in bidding through us. Should you experience any problems with bidding online, please contact us and we will find a solution.

Can I cancel my bid?

Yes, up until two hours prior to the auction’s first lot end time. Please note that you can cancel a maximum of three bids per auction session.

What guarantee do I have as a buyer?

All lots we offer have been physically examined and described by specialists, thus the authenticity is guaranteed. Moreover, we do take responsibility for our catalogue descriptions. A lot may be returned – in the same condition – if any serious defect not mentioned in the catalogue is found.

What are the payment options?

Invoices are sent to the winning bidders per email directly after the auction. You can make a bank transfer or otherwise pay with a debit card or cash in our office. Payments by credit card are also possible but are subject to a 4% surcharge on the total invoice amount up to €1.000; on invoices from €1.000 to €2.000 the surcharge is 3% and on amounts exceeding €2.000 a surcharge of 2,5% is applicable.

How can I verify my account on Invaluable?

Due to the new Anti-money laundering directive, bidders are required to verify their accounts through Invaluable if looking to leave a bid of more than € 7500 (This is accumulative over a sale). Please ensure that you complete this process before the sale so that your limit is not restricted. Click on the following link and verify your identity:  Please note once you verify your account you will not have to do it again via the site for any future auctions.

Where can I pick up my artwork?

You can collect your purchases on working days from 10.00 to 17.00 CET at Adams, Herengracht 458 (ground floor), Amsterdam. To inform us about the time of your visit, please send us an email.

How can I request shipping?

Please let us know if you require shipping by sending us an email after the auction, and you will receive a new invoice with the shipping costs. The charges vary depending on the size, destination and value of the work, amongst other factors. We will gladly assist with arranging the best shipping option for every particular case.


How are items valued?

Items are initially valued by specialists based on the image and short description you submitted. Auction estimate we provide is an indication of the price we expect for the item to fetch at an auction. It refers to the current market situation and recent auction results for similar work and does not take into account the amount the item has been purchased or valued for in the past. Valuation is free of charge and without obligation. If valuation is successful and you decide to sell the item with us, it has to be delivered to Amsterdam for expert examination. Finally, definite estimates and a starting bid are fixed in the consignment contract.

Where and when can I deliver my consignment?

Items can be delivered on working days from 10.00 to 17.00 CET at Adams, Herengracht 458 (ground floor), Amsterdam. To inform us about the time of your visit, please send us an email.

How much is the commission?

Our commission is between 10 – 25% of the hammer price depending on the estimated value of the whole consignment. The commission includes all the costs for professional expertise, photography, research and cataloguing, as well as promotion and exhibition. All further charges are for our account and risk, with the exception of insurance and storage costs (1%). If the item remains unsold, you do not pay anything.

Can I set a minimum price?

As the owner of the item, you have the full right to decide on the minimum price you want to sell it for. As the seller, we will then consider if it is sensible to offer the item for it. We can not accept a minimum price above our auction estimate.

How can I follow the sale?

You will receive a notification as soon as the auction is online. From this moment on you can find a link to the catalogue on our website, browse the lots and track all the bids placed. On the final day of the sale you can similarly follow the auction on the internet.

Can I cancel the sale after the auction?

No, the hammer price is binding for all parties.

Where can I see the sale results?

Our auction results can be found in Artprice and Invaluable online price databases. Prior to the bank transfer, a consignor receives a net return specification based on the auction and aftersale results.
