Hey Everyone! Was hoping someone could help me identify if these were authentic or not. They were originally mounted in 18k gold earrings. They are high carat gold (18k+), but I can't find anything that matches the designs exactly. I know they may be copies, but wanted to be 100% sure before they get melted!
Left coin is 4.1g and measures between 12.73-13.07mm
Right coin is 3.6g and measures between 12.60-13.11mm



Your assistance is very much appreciated!
