Japan
Meiji Yen Year 13 (1880) MS63 NGC, KM-YA25.2. Charming for its originality with an alluring array of mixed gold and green tone on the obverse that lightens to copper-golden highlights on the reverse. Mostly mark-free, a small milling mark at 10 o'clock inside the obverse beading, as well as a tiny ding at 11 o'clock on the obverse rim, are worthy of mentioned, and likely precluded an even finer grade.
