Anyone know any more about such a coin? i received one off my granddad who got a few from a friend at a bank. I dont ave my collection with me at the moment, but they were issued for one of the outer Isles such as Guernsey or Isle of Man. i hear they didnt take off and were not issued for general circulation. They are a rounded square shape if i remember correctly.
I am not sure about all i have said, hence the post, curious though how many others there are out there
