Question about 1991 Factory Sets

[JoeDfan]

Factory sets I ripped into always had the corrected versions of the good cards.
However, I sometimes have decent luck with those old Topps vending boxes.

Do we know the ratios of some of the more glaring errors, like Chamberlin, Gonzales and the misnumbered checklists?

[JoeDfan]

I literally buy boxes of these cards all the time. Chamberlain, Gonzales, etc., are pretty easy to find. It really depends on how detailed you want to get. There are "bold" 40th logos on back, faint ones, "pink" spillover in the numbers, some of them backs glow under UV lights, etc. All fairly common to find, but in so many combinations it really becomes difficult to acquire all of the "versions" on each card.
Then you have your Drabek and Hoiles white inner border cards, which are much rarer than the usual errors. Whiten hand-over border I think is super rare, I think. Junkwaxgems guy said on his website something to the same effect (check out his website for lots of commentary on this set, actually). He also lists a couple of other ones that might be more scarce than these ones also.
Good luck. Once you start down this road, it is really hard to stop!
