Babe Ruth Card Question
 

Can anyone tell me the difference between the 1921 Koester Bread George Ruth
L.F. New York Americans and the 1922 W575-2 George Ruth L.F. Americans?
Both cards are blank backs...I am stumped!!!!


How can a grading company tell which one it is?

Thank you for any input.

I think they are very, very similar, but the paper stock is slightly thicker in one of them. Here are a couple threads that go over more of the differences in the Koesters vs w575 sets:

Interesting on both cards mentioned part of the "r" on Americans is whited out. I would love to hold both in hand and compare.
