I can't for the life of me figure out let's say for example on the Numista site what the ND stands for when they list again for example a 1930 ND 10 Yen. Can you please help explain? I have seen it on other listings elsewhere too. Is it like BCE OR ACE (BC OR AD) OR does it mean Nippon Denomination? Ik I'm reaching but it's hurting my head.
