I could use a clearer pic of the reverse.
What is that polished medallion with the eagle?
I’ve looked for it but I can’t find anything but at first I didn’t see it as being something real or even rare
I can’t read some of it so I’ll do my best
Eagle side:
1848-49, 1855-59, 1860-61, 1866, 1870, 1913-14,??, 1935-36
