I remember going as a kid to an auction in "Casa de Moneda" in Mexico City, with my grandfather 20 something years ago. He was the only bidder for this gem.
I lost track of it until now that I was looking through some old stuff and a coin collection he had.
I felt a lot of joy to find it again as he means a lot to me.
Doing a little research I found this community, could anyone tell me a little bit more about its chops?
Thank you :)
