I agree with bikergeek. It is unpleasant to realize that you lost only because you did not press the button and did not offer $ 5-10 more than your previous bet. I can't remember the specific coins I missed, but it was a shame to lose to another collector because of the difference of less than $10.
Some auctions (
ebay) force you not only to have the biggest wallet, but you also have to have the fastest hand in the wild west.
