Hi folks, I am looking for some help with this penny my dad has had for years. I said I would try and find out some info on it for him. I tried googling and found some info about one sided pennies being used for pub games hence the one flat side. This coin though isn't flat, it has the reverse imprint of the queens head and a raised ridge around the edge which I tried to capture in the photos. I though some of you knowledgeable lot could help with the reason its like this (maybe its common?) and an idea of value if it is worth anything?
Thanks for your help!
