How do you tell if a 1949 Babe Ruth Leaf Gum is real or fake?

So as I said in a previouse post I recently won 9000 baseball cards at an auction, and since I found some really rare rookie cards and non-rookie cards I contacted the woman who auctioned them off to see if she went through them before putting them up for auction.
She told me that her cousin willed them to her, and that she did NOT go through any of the cards as she wasn't into basbeall or baseball cards and it was too daunting of a task.
Well I went through some of them, and found a 1949 Babe Ruth Leaf Gum card. It was in pretty good condition, but did show signs of age and had some discoloration. So I did some research on the card and it seems to be pretty authentic, but some reprints look scarily similar to the originals, so i was wondering if you guys here know how to tell a fake 1949 Babe Ruth from an original 1949 babe Ruth.
