Art Auctions, from Viewing Day to Gavel

Every serious auction is preceded by several days when the lots are on public display, usually free to attend and open to anyone, not only registered bidders. This is the moment to look closely, since photographs in a catalogue rarely show a surface texture or a small repair the way standing in front of a piece does. Bring a torch if you plan to examine a painting's surface closely, and ask a specialist on the floor any question that occurs to you. They are there for exactly that.

Take notes during the viewing rather than relying on memory once several days have passed. A lot number scribbled beside a quick impression, promising, overpainted, smaller than expected, is worth far more on the day of the sale than trying to recall a dozen paintings from a single walk through the rooms. Many serious bidders visit twice, once to survey everything broadly and again, closer to the sale, to spend real time with the handful of lots that still hold their interest.

Each lot carries a low and a high estimate, a range the specialists believe the piece will reach, though the final price can land anywhere including well outside it. A reserve, the minimum the seller will accept, sits quietly beneath the estimate and is rarely published. A buyer's premium, a percentage added to the hammer price, is charged on top of whatever you bid, so the true cost of a lot is always higher than the number called out in the room.

Provenance notes in the catalogue, a list of previous owners and exhibitions, are worth reading in full rather than skimming. A well documented history rarely changes what a piece looks like, but it says a great deal about how confidently it can be sold on again later.

Bidding in the room, paddle raised, remains the classic method and the one that teaches the rhythm of an auction fastest. A phone bid lets a specialist call you at the moment your lot comes up, useful when travel or timing makes attendance impossible. An absentee, or written bid, sets a maximum in advance and is executed on your behalf, the safest option for a first timer nervous about being swept along in the room's momentum. Online bidding has grown steadily and now runs alongside most sales as a fourth option.

A successful bid becomes a binding purchase the moment the hammer falls, and payment is expected promptly, within whatever period is set by the house's own conditions of sale. Collection and shipping are arranged separately, and a specialist auction house can usually recommend a shipper experienced with fragile or valuable work for anything travelling abroad.

Keep every document the auction house provides, the invoice, the condition report and any correspondence about the lot, filed together with the piece itself. Long afterward, should you ever wish to sell or insure the work, that paper trail matters as much as the piece it describes.

Karolina has the particular kind of stillness an auction room rewards, attentive without fidgeting, and a genuine interest in how a formal room like this one runs its own choreography. Margo, one of four companions in the collection aged 30 and over, has sat through enough sales to read the mood of a room within minutes, useful company when deciding whether to raise a paddle one more time.

Auction houses in Amsterdam Centrum hold viewing days and sales throughout the calendar, and an afternoon at one pairs naturally with a formal dinner afterwards, particularly if the sale has gone well. Companions suited to business events read a saleroom with the same ease they bring to a reception, and the coordinator can confirm who is available once you know the date of the sale. The steps for a first reservation are set out in full on the reservations page.
