I'm looking for some help identifying these Asian coins. The first says 1 sen and I think it's Japanese. I just need confirmation and the year. The second one has a 1 and all the other characters are Asian. This may be Japanese too. The third says 1/4 Yang and the rest of the characters are Asian.
This last one doesn't look like anything I've seen so that intrigues me. Maybe Thailand, but I don't know.
1) Japan "one sen" 1885 (Meiji 18 year) 2) Japan "one sen" 1916 (Taisho 5 year) 3) Korea "1/4 yang" 1898 (Gwangmu 2 year) Gary
