I have collected all Topps and Bowman sets, all ungraded. I personally like gum stains. For me they are a nostalgic part of the hobby. But I get why another collector might be disappointed. And I would think less of an auction house that did not think it worth mentioning that a large number of cards in a lot had such stains
On the other hand, I was not a fan of Topps Heritage artificially adding gum stains to some of their cards recently
