1963 peel off instructions vs blank backs

[sflayank]

dont know why there are 2 variations but without a doubt the 7 to 1 ratio will hold up....i searched many years to complete the blank back set...every pile of 100 peel offs that a dealer had you find 10 or so blanks and always the same players too
i understand some of psa with variations but thia variation is so ridiculously obvious that no knowledge of cards is needed to distinguish

I am of the opinion that there are actually 3 variations to this set.

The instructions version has what I call "hands up" and "hands down" variations.

While I expect that some of you will disagree with me on this "extra" variation, I'm confident that if any of you found a card where the back was printed both "right-side-up" and "up-side-down" you would call it a variation.

From my experience, I believe that the ratio of backs is approximately :

Hands Down - 60%
Hands Up - 30%
Blank - 10%

Here's a picture, so you'll see what I'm talking about, hands down, blank, hands up.

I think they just stopped inking the backs at the end of the run (or second run).

the pop count is now 108 with instructions 19 blank backs
