100 yen coin

The 100 yen coin (百円硬貨, Hyaku-en kōka) is a denomination of Japanese yen. The current design was first minted in silver in 1959 and saw a change of metal in 1967. It is the second-highest denomination coin in Japan after the 500 yen coin.

History

The first 100 yen coin was issued in 1957 and featured a phoenix on the reverse. It featured English language writing in addition to Japanese. This design was issued in 1957 and in 1958.

In 1959, the design was modified, removing the English wording, and changing the reverse side to show a sheaf of rice. The metallurgy remained unchanged. This design was issued every year from 1959 to 1966.

The current design for the 100 Yen coin was first issued in 1967. The metallurgy was changed from the former 60-30-10 ratio of silver-copper-zinc to a ratio of 75-25 copper-nickel, with the weight and diameter of the coin unchanged. The reverse side was changed to show sakura blossoms and the denomination in Japanese.

The coin shares, with the 50 yen coin, the emperor's rule date (28 in 2016) expressed with Latin numerals instead of in Japanese numerals.
