Martin Luther King Dug Medallion Richmond Va.

Description

This Martin Luther King " We Shall Overcome " medallion was dug by the banks of  the James River alongside Civil War relics. I'm not sure what material it's made of. It belongs in a museum and likely from the Civil Rights era 1964. 2 1/4 wide around 1/8 thick. I've never seen another one like it and could not find one on the internet. It comes with a case. Dug condition.
