Kevin,Thanks for your reply.What is the purpose of doming the coins and is that done with a press, heat, hammer?Not sure what a Chicago screw is or how to solder to coin silver. I guess I could do more research and or find a jeweler to do this for me. My hope is that there was a way to attach them w/o damaging them. I have seen coins with a band around them to use as pendants on necklaces and thought there might be a band that fit the coin, then had prongs that would go through the belt and be bent back on the back side of the belt to hold them in place. I thought there might be something like that.Lee Thanks for replying.I don't care if the attachments show on the back or not.What might be a method to attach the coins to a belt? Any ideas?Thanks.Lee
