Understood, I was thinking mainly about collectors who are seeking strong grades in certain respects that are important to them, but not necessarily absolute perfection. I probably don’t have the most well-trained eye for what places a card in the PSA 9.0 to 10.0 stratosphere, so I could be clueless as to the relative scarcity of cards that would make that cut. I was just recently thumbing through a few hundred common stickers from Series 3 to 8 that I had bought in various eBay lots over the years, and a lot of them look really nice and sharp to me, but for all I know, maybe none of them top a 6.0.
Given the relatively poor production standards of the era, the fragility of the flimsy card stock and tendency toward yellowing/browning over time, top-grade Wacky collectors really have their work cut out for them.
