The amount you bid depends entirely on what the lot is, and how you and other bidders feel about it. Because prices are determined by a completely open, competitive market, they are often impossible to predict in advance. One tip when bidding is to consider your maximum limit, and follow your gut feeling. One common mistake is to bid too little, and then regret it when someone else places the winning bid. Please feel free to ask our staff for advice if you feel unsure. Checking what similar items have sold for on metropol.se will also provide some guidance.
