Vintage Crocodile Skin Bag

This is the bag I was telling you about from Goodwill. I was attracted to it before I read the inscription inside which says...
"Genuine Crocodile Skin." If you look real closely in the picture below, you will see it. It is written in gold, so it is lost against the light. I don't know if I can believe that it is real, but considering how old it is, maybe it is real. For $2, it was worth it to me even if it wasn't real.
This is not the outfit I would wear with this bag, but just so you can see the size of the bag in comparison to me, I took the shot.

Does anyone know how to tell if a bag is genuine crocodile skin? Should I just believe the tag and not be so cynical?
