Wow, I can't imagine finding anything so old. I love the ring, what do you think the stone is? I really like the coin in picture #7 too. You have made some great finds with that machine!
On the 7th pic is the Sigismund III's 3 groschen from 1598. Image Gallery of Polish Coins
Ring... I think the stone in the ring is blue glass, maybe from 19 century.
Incredible Finds! Way to go! Each one is a work of art that captures life in that time! I am so glad that these coins are still found and shared so we can see them. I always wonder what old coins would have been worth in the time they were circulated? Thanks for sharing!
