But many people who are regular buyers at auction houses eventually get burned. Some of them come back. Some of them stop.
Look at Auction Houses dealing with Rudy Kurniawan, the famous wine counterfeiter. The auction houses knew some of the bottles seemed too good to be true, even from an established wine collector as Rudy Kurniawan was. But they auctioned them anyways because they wanted the publicity of being able to get such famous bottles.
Time and time again has shown one thing. Those who trust auction houses, sometimes get bitten. You can fool some of the people all of the time. You can even fool all of the people some of the time. But you can't fool all of the people all of the time. I've been fooled. Heck, I've been fooled multiple times and yet I still keep on going back! Family members wonder, "when will Patrick learn his lesson?" I've personally experienced a problem with auction houses 4 times in the past several years; and each time I've had a problem, the auction houses were very difficult to deal with.
