I am not sure of the type of coin rings are talking about but in
1944 I made rings out of a US quarter. Drill a hole in the center
and insert a center punch. Place it across the slightly open jaws of
a vise and tap around the periphery. The center hole gets larger and
the outside gets smaller. Anneal several times If you are lucky the
date will show on the finished ring.I was 19 at the time and knew
nothing about metal work. I learned by word of mouth
