Hello all. First time posting, so hello to all of you. Please be understanding if I have missed some rules or guidelines. So, on topic. My father is a goldsmith, and few years ago he found a coin in an old cup (trophy) of some kind. I would like your help to find the origins of this coin, as well as potential value. I did try to google, but could not come close. It seems that coin is from 1602.and it is silver. Pleas find two photos below. Looking forward to your help. Thank you.
