50 Yen - Shōwa

This issue replaced the earlier 50 yen nickel type (Y#75) when Japan's postwar economy had stabilized sufficiently to justify a redesigned coinage. The hole was dropped for this series — an unusual reversal, since Japan had been punching central holes in minor coinage since the Meiji period. The perforated format returned with the subsequent type in 1967, making this the only holed-free 50 yen in the modern series.
