Rare vintage 18 k and Emerald Mexican biker knuckle ring rare find from 1940s

Super rare find! You will probably never see another! The piece is marked coin which means coin silver. Coin silver is old. I believe this ring is coin silver and the skull and cross bones may be copper then they used an 18k overlay. The eyes are Emerald. There is Hand engraving on either side. It’s a ring for the top of your finger or to be worn around your neck. Not sure the size, approximately 2 1/2 inch around. This is so cool, Enjoy!! This is a Mexican biker ring from the 1940s. Each one is masterfully made and different. This one is in excellent condition!
