I have a coin or a medal. It is about the same size of a sovereign, bronze/copper, weight 4grams, no milling around edge, with a double obverse of King George V. There is no legend or date, just the head. Does anybody know what this could be? I would class it in VG condition, but it does need a clean, which I am hesitant to do - if cleaned it could possibly co me up a grade. Photo attached - sorry, best I could do! Thank you in advance for your opinions.
