Unknouwn year of chineses coins. [opgelost]

I don't know what is the year, could you help me?

Thanks.

First of all, they're japanese.

For the 10 yen coins, #1 is dated Heisei 9, which is 1997 in our calendar. #2 is Showa 53 (1978).

For the 5 yen coins, #1 is Showa 50 (1975), #2 is Heisei 4 (1992), and #3 is Showa 40 (1965).

Thank you.

Você pode usar o buscador por imagens do Numista e achar a página delas, depois só comparar os caracteres e vai chegar no ano de cada uma.

Muito obrigado, vou utilizar isso.
