Hi all, please find attached a photo of a coin I recently found (in the uk). I have done some quick google searching but cant find anything else like it and would like to find out a bit more about it. The writing on it says 1 11 PITT SHILLING and of course has the large number 1 on one side, the other side is very well worn and has green copper stain on it. Obviously I dont want to clean it until I find out more about it, if at all, so any info you could give me would be greatly received, thanks, Barry
