How does a timed online auction work?

A Timed online auction takes place entirely via the internet. You bid by automatic bidding. This means that you can enter a maximum bid for the relevant lot and the system will then bid for you until you are outbid. You can always increase your bid in the meantime. In case of two equal bids, the lot is awarded to the first bidder, but the other can always increase his bid.

The auctions are closed in stages. This means that 20 lots are closed every 5 minutes. When someone bids in the last 5 minutes, the auction of the relevant lot is extended to 5 minutes, so that the counterparty has enough time to make a higher bid.

You will receive an e-mail up to 5 minutes before the lot closes, if you have bid or are outbid. After that you can only see that in the catalog.


These are the increments:

20 100 5
100 200 10
200 1000 20
1000 2000 50
2000 5000 100
5000 10000 200
10000 50000 500
50000 - 1000

With every purchase, 30% premium and 1 Euro table money is charged on top of the hammer price.

Please note: resale rights may apply to some purchases.

Contrary to art. 2, the auctioneer is prepared to take back the auctioned gold and silver works (with the exception of gemstones), paintings, watercolors, drawings, bronze sculptures, if the first and last name is stated, against a simultaneous refund of the purchase price and premium, on the understanding that within a period of 10 days after the date of sale proves to the satisfaction of the auctioneer that the description provided is so incorrect that if the correct description had been known to the buyer at the time of the sale, he would have renounced the purchase or would have bought only at a significantly lower price.

  • Not to transfer goods from the original purchaser's account to that of another reflectant.
