I found this in a coinstar machine. I know these are very common, virtually worthless coins EXCEPT those with the number 58 inside the star and UNA GRANDE LIBRE stamped on the rim. this coin appears to meet the criterion but I’m not at all comfortable with my understanding of these so I’m asking if anybody can confirm or deny my assessment. If it is one of the good ones, how would you grade it? There’s a bit of rim damage. Finally I read they can be worth up to $400. Does that sound right? I know valuations fluctuate and people tend to exaggerate but I’m curious. Gracias!
