A client came to me with two old bracelets made from old threepenny bits. They ranged in date from 1897 to 1940. The bracelets had seen better days, and my client asked if I could take two of the 1917 coins off and create cuff links as a gift for her husband.
It was slightly daunting to be working with 100 year old coins, but the cuff links turned out ok!
