I had a man's wedding ring made by a fellow on Tnet a couple of years ago and wear it everyday. It has the year I was born displayed on the outside (1944). It was made from a USA half doller with silver content and stays bright and shiney just from every day use. It has began to wear a bit and the date is no longer very legible, but it was not the greatest sample I've seen, just one I was given by another Tnet member. Monty
