These "coin rings" were a very popular past time of some navy sailors. You
beat the edge of the coin repeatedly with the back of a heavy metal spoon
and eventually it mushrooms out. My dad used to make them on the ship he was
on. You need to use a real silver coin, a half dollar. He made 2 about 10
years back for himself & my mom as gifts. Took them to a jewelers shop when
he had finished the rough ring and had them sized. Very cool. I made one out
of a quarter when I was younger. I remember the noise going on for weeks.
Needless to say not a quick process, but cool nonetheless.
