Interesting 75 variation/error?

[steve B]

I collect both variations and printing errors. There's a handful of cards like this one that I'm just not sure which group it belongs in.

I've a fairly loose definition of variation, counting anything that I can put down as a difference in the printing plate or a certain difference in the production equipment like die cutting mats. The vast majority of those differences are trivial and seldom listed anywhere.

For instance, some 75s are glossy all over, while some have no gloss over the white areas. The same thing happened with the backs of 93 upper deck. 3 varieties, one has gloss over just the picture one has gloss over the entire card, and a third looks like they were done with just over the picture then glossed completely.
91 topps come with not only the light and dark logos, but with ink on back that glows under UV light or ink that doesn't. I'm probablythe only person collecting those.......
