I recently bought a lot of foreign coins while purchasing some morgans, in the lot was an 1820 ferdin vii 2 reale, I have found some information but I can't find any coin for that year that has after the 2 r an A. G., they all have other letters that I have seen, I don't know if it is a mint that I haven't seen or what. Any help would be appreciated, also I judge the coin to be in fine condition and wonder if anyone could give me a value from g to fine
