Make a Half Dollar Silver Ring

I was surfing Reddit as I often am when I came across a guy who had posted a thread about a ring that his father had made from an American half dollar coin. I often find myself with nothing to do and this piqued my interest. After some googling I found that all pre 1965 American large coins were made from solid silver, or thereabouts, and these are easy to turn into a ring. So at that point I jumped on eBay and bought myself a Half Dollar coin, a 1958 Ben Franklin coin to be exact for £7 delivered, bargain! A bit of further searching and it would appear I could flog it to the yanks for about $40 if I could be bothered, I couldn’t, so ring making commenced.
