JNDA 01-46. The sen is valued at 1/100 of the yen. The inscription across the top of the reverse translates to '100 pieces in exchange for 1 yen'.
Like the half sen, the full sen was minted non-continuously from M6 (1873) through M21 (1888). The denomination has two basic styles, with the earlier style having a dragon with 'squared' appearing dragon scales. Later issues have a 'sharp' scale style but without an overlapping year as seen in the 1/2 sen.
