Hi! I found this silver coin at Hungary! It’s probably from 17-18 century because I have already found similar coin to this! It is less than 1g! Can you identify?
I found the exact same coin like mine!My vote is for Poland's Frederick Augustus II as shown here:
1753 POLAND King FREDERICK AUGUSTUS III Antique Silver 8 Groszy Coin i110806 | eBay
Poland under Frederick Augustus II (aka Augustus III) - King: October 1733 - 5 October 1763. 1753 Silver 8 Grozny 28mm (6.92 grams). Reference: Kop# 2117, Kop# 2118, Kop# 2119, Kop# 2120, Kop# 2121 (1753).www.ebay.com
The "G" behind the crown also looks similar to both your coin and the above reference coin.
