1960 McCovey AS corrected card?

[Nippy7]

This may be a simple question and maybe embarrassingly irrelevant, but I have 3 1960 Topps #554 McCovey's and two of them are printed with graphics that are slightly different than the third one. Every #554 card offered on E-bay right now is the what I'd call a "corrected" version and two of mine are the "uncorrected" version. None of the info is changed, just the graphics of the black shadow - see McCovey's right shoulder and bottom red bar (and a few of the printer's dots removed - see detail). The backs are identical. I've searched online for notations of this and nothing comes up. I can accept it as inconsequential but in our collecting environment, it seems a difference is usually noted.

So I wonder if anyone knows about this (or cares). Is this common?
And should I sell or trade them as the same?
Thanks.
