I'll find something pristine in an MS66 or MS67 and then place a bid. My bids are usually about 30% of the going market rate for the coin in question. At any one auction I may have a couple of thousand dollars in bids and be winning... for a couple of days, only to get outbid to the tune of 3X my initial bid; however, that isn't what is important. The important thing is I get to pretend to be a high roller for a few days. Me? I'm a very serious collector of high end coins... why I've got thousands in bids out on Heritage Auctions as we speak.
