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

Greg,
Welcome to the forum. There is a lot of knowledge to be had here and some nice fellas. I'll have a look at my '54 Aaron when I get home tonight to compare. There have been quite a few versions of PSA cases, and I believe the white + hologram looks legit. I know there is a thread somewhere on Net54 going over each version of the case and what it should look like, front and back. That is an older slab with the white printed on the case + sticker, and the front says PSA in rounded letters, which matches. They changed the front font as well as making the writing on the back of the flip totally inside the slab after that. It's hard to tell by the pics the degree of case tampering, although there are members here that may be able to tell by the photos.

I'm no help on the '55, sorry.
