Interesting rounds! Like their ancestor, the Spanish Milled Dollar (AKA "Pieces of Eight" since they were often cut into 1/8s for transactions), these rounds are set up to become "Pieces of Four"!!!

"Pieces of Eight" were commonly used as currency in the USA throughout the early 1800s and only ceased as such when sufficient U.S. coinage was in circulation!

I guess I have a spatial relationship problem. They are 39mm. They were bigger & heavier than I expected. Pretty cool stuff.
