Hello I have a 1791 George III spade coin but there is something odd about it. Everything I’ve read so far says that it should have writing around the coat of arms spade side that starts M B... My coin, however, has J R ET JW REX F D T (there is a hole here so missing 1-2 letters) N(maybe)BY ST C M S P ET C and then at the bottom is 1791. Can anyone tell me anything about this coin including its worth? I’ve attached pictures. FYI the actual coin is a bit clearer than the pics show (but this was the best I could do without a better camera). Thanks. Gerry
