Hi I found this large copper coin while metal detecting in a field near cockington village, Torquay in United Kingdom it is very worn and not much to look at but it does have very distinctive indentations off to one side on either side of it. I think the shape of the indentation is either square or shield shape. The coin measures 32mm and around 4mm thick. I have never seen a coin before like this but I'm sure someone who has seen one like it would easy recognize it via the location of the square/shield shape dents. Any help on this one would be great, cheers guys
Many thanks Richard
