New to the forums and wanted your thoughts on these two Aarons I purchased last week

Nice pictures for a digital camera! Lots of people do far worse with a scanner.

A bit of what you're looking at is registration. On the 54 the red is printed a bit low and to the left. That will make some red print be below the inmage at the botom, and also make the orange background appear slightly left causing the indent for the gray of the uniform. It's also what makes the red of the feathers show up to the left of the headdress outline on the logo.

I can't really see the gray line above the fielding pic. There's a few things that could be. I don't have an Aaron to compare, but there are lots of little differences in many Topps issues that aren't really recognized as variations but are there.

The dots left of the logo are also tough to see, but stuff like that is pretty common on 50's cards. It's usually from a bit of ink spatter from overinking.
(Some could also be plate differences caused by dust in the photo or platemaking process, but I'd have to see a group of identical ones to feel confident calling it that)
