Hi everyone!
I purchased a 17th infantry Buffalo Bill coin with the dates 1950 and 1953. I'm hoping it's authentic but I'm having a very hard time figuring it out. I've read conflicting info on the material, and wear, and hole and crest. I've been comparing pictures of what I purchased to other alleged authentic coins and notice inconsistencies in color, the shape of the buffalo, the crest design for that year, etc.
I'm looking for help, can anyone tell me if this is authentic or did I buy a really good replica?
I should add, it weighs 5.03 grams.
