I heard about coin rings a few months ago on FB, after watching alot of YouTube videos I decided to buy some tools and give it a try. I bought a ring mandrel and a dappingblock set from amazon, punch and die set, 15lb anvil and a nylon mallet from HF. I found an easy way to find center of a coin(YouTube video) punch a hole in the coin, then anneal the coin. Put coin on the ring mandrel and hammer away. I'm making these for Christmas presents this year, so I've been using "state" quarters for certain people. Here's a few pics of what I have made, mostly U.S. quarters and 1 U.S. bicentennial half dollar and a few foreign coins.
