They are print errors.

But neat ones :)

Echoing Ben, print error.

Another "near" print error. Definitely some blue pixels visible in the "a". Likely as close as I will ever get to the real variation.

Some partial border-less 63s, with some near "black-lessing".

Larry/Cliff---are these 63 missing borders related at all to the group Cliff identified earlier for Sadowski/Bell/St Louis Team/Herbert/Mele/Klimclock/McCormick/Cook ?

Here is my Herrer but I like the one on left better

They have me perplexed. They are from the 3rd Series and are all over the sheet, I don't see any pattern as to why they are like that. When I saw them I figured they were all on the edge of the sheet like the ones from the 1963 1st Series and 7th Series but they aren't.

I had looked at the sheet you posted previously and the only adjoining cards in my group were the 3 yellow cards....however, they had missing ink all on the same left edge. It would have made more sense if the adjoining cards were borderless on their shared edges (IE one left edge, the other the right edge).

My guess is that there are cards from the 2nd, 4th, 5th and 6th series that have similar flaws. They just have not been shared yet.

Not the most exciting, but 1967 Topps #383 Ken Henderson comes with or without the small green splotch on his neck.

1970 Topps #19 Johnny Boccabella comes with or without this small blue extension from the biography box, above the card number.

These are both the white stock reverses.
