Hi All,
 
	Just joined as I wanted to pick people's brains. This is a coin I found in a Victorian house about 5 years ago underneath some lining paper of an old fitted cupboard. I've looked it up and it seems to be a King George III half crown dated 1817 as you can see. But the one thing I don't understand is the GN in italics on the face side of the coin. I'd read somewhere of "mint marks" but this seems to be associated with American coins more. Just wondering if anyone had any ideas. 
 
	(I also see from a quick browse online that this coin is actually worth something!)
 
	Best wishes
 
	Richard
