I made these bowl-shaped earrings from a 1964 American silver coin. When making a coin ring from a half dollar, the center is punched out. I used the center of the coin to make these earrings. The earring posts are securely soldered on, so they won't come off. ○ Silver Coin: 1964 American Kennedy Half Dollar ○ Coin Material: Silver 90.0% ○ Diameter: 12mm ○ Earring Posts: Silver 925% ○ Earring Backs: Silver 925% Please ask if you have any questions. #ReD #Accessories
