I acquired this interesting stamped coin about 2 years ago from a man in Carrickfergus, Northern Ireland.
This is a 1937 / 1946 style Half Crown made into a key ring by a Loyalist prisoner in Maze Prison likely in the mid 1970s to the 1980s. The ring was included with it, though I haven't pictured it. The coin and the hole both show heavy wear, so it was used for some time. The UDA (Ulster Defence Association) badge is colored in with paint or ink. The motto "Quis Separabit" translates to "Who shall separate us".
Many items were made by prisoners, including leather goods, jewelry boxes, prison art, etc. and sold on the outside to raise money for prisoner's families. I also have two small leather key rings and a wallet, the wallet being marked and dated by the maker. These were acquired more recently from a different source.
I'd be interested in any information anyone has about this prison art. Also, I'm guessing about the date range of the host coin, as it's so heavily worn. Any help on that would be appreciated too.
