I'm new to coin collecting and I'm not sure how I came into possession of this coin (I beleive it was given to me by my grandfather). However, I'm concerned with its authenticity due to its good condition and I've read that the 1821 8 reale Zacatecas mint is one of the most recreated / counterfitted. The coin feels like real silver and the weight seems accurate. Let me know what you think!
P.S. ignore the copper/gold tint at the top of the coin as that is from the lighting when I took the images.
