Coin Ring This is the first ring I made from a 90% US quarter. I started by putting a hole in the middle of the coin, and attaching to a long bolt. It helped me hold onto it for a while, but then when I started going inwards, they folded over and didn't quite meet up in the middle. It's hard to decide if I should've only done the outside and drilled out the rest but I didn't want to waste any metal, and getting it onto my fat finger was hard enough as it was.
