@kts, first welcome to CCF. Second, as it looks like you have either real or counterfeit 18th Century Spanish Colony coins, I'm going to move this thread (again) over to the world coin section. There are a few folks who hang out over there who should be able to help. In the meantime, please post the weights of these three pieces. Thx.
