Very unexpected and impressive results, Dan! It looks like the date is 1831? Did you use any kind of aggregate when you tumbled it?

Tony I use the equivalent of uncolored aquarium gravel and a dab of dish soap , copper coins are usually tumbled for only a couple of hours at a time before being re-evaluated for longer or not. some of the brass items may go longer .

Dan

I gotta try the tumbler again.
