They don't vary a whole lot in my experience. There are a ton of fakes that fool experienced collectors and dealers. I remember a few years ago at the National, I saw a fake one being sold...I was 100% sure, no doubt. I never could convince the dealer it wasn't real. It wasn't. Just imagine a deck of playing cards that is 100 yrs old. They start out fairly white and turn a bit cream colored over time, with age. But they don't turn "grainy" looking like the reprints and they don't turn brown'ish like some reprints. The course grainy look is the dead giveaway to them being reprints....some are better than others though. .Check out this link to see the grainy look I speak of.....This is what they should look like.....(my 2 types)
