I found this coin in a pawn shop. It's not worth much of anything, so I was able get it thrown in together with some other things I was buying for free. I think it's a pretty neat looking coin. It's got some good toning and it's almost 50 years old.
Sadly, it is not silver, though they did make a version that is a sterling silver proof. It's a pretty large coin. The last pic has a quarter for size comparison.
You can find more info about it here. Pics are mine.
