Bought this Gold 1/10 ozt libertad a few weeks ago, and the seller said it was a "mint error" I didn't think much of it and didn't pay a premium for it so I'm happy either way. Actually I paid $175 so yes there was a little premium. On top between "Oro" and "Puro" is what im talking about. I dunno if that makes it special or not, I was just curious. Thanks for the feedback.
