I made this ring with a ring blank and pound that I still had from my last trip to London. Since it's a beautiful coin I decided to glue it onto a ring blank and taaa-daaa, there you have a pretty new ring!
I had to use super-special glue because metal and metal does not really want to stick together.
If you take a pound like I did be prepared that it is quite heavy. This will work with other (and smaller) coins just as fine! have fun
