BELIEVEINMIRACLE coin ring. This ring is made from a U.S. Mercury dime (silver coin). The Mercury dime appears to be from 1945. (1945-w) Although I have never used it after purchase, there is some blackening due to the silver. I polished it as much as possible, but if you are concerned, please polish it yourself. Material: Silver (The coin part is also a silver coin, so there is some blackening.) Size: Approximately size 14 (inner diameter approx. 17.5mm) *Please note that this is a rough measurement. Please understand that this is a used item, although it is unused. Blackening has occurred due to the nature of silver. Please note that there is no case. I am also selling several other accessories. If you would like to purchase multiple items together, please contact me.
