warshawlawIf the value of the pop report is in the rarity of the high end cards for the registry builders doesn't it dramatically affect values when cards are resubmitted, thus doubling or tripling the pop? I would also think that it might affect the price a seller could get for his card if someone thinks there are more out there...
The most "significant" card I have that was cracked and resubmitted is my Aaron rookie, which went through PSA 3x by the dealer who eventually tired of the quest for an 8 and sold it to me as a 7.
I've cracked out a bunch of PSA and GAI cards (and a few SGC cards); never occurred to me to return the flips. Maybe they should put a 5-cent redemption value on them like soda cans. of course we'd then see bums digging through the trash outside Scot's house looking for flips to return 
I've never cracked out a PSA 7 or 8 card but I have submitted a number of PSA 7 cards to SGC to cross over and in nearly all cases received an 86 on the cards.
