Ed HansTo further illustrate Steve's excellent analysis, In may of this year a D304 Cy Young in PSA6 sold for over $80,000 in a well known auction. Allegedly there were three people bidding aggressively on it. In September another PSA 6 Young fetched only $18,000 in an equally well publicized auction. Part of the explanation for that result is that there was a PSA7 Young scheduled to end about two weeks later. That PSA7 went for "only" $24,000. It's easy to see the effect that one or two fewer bidders can have on high end cards.
