In 1601, Keicho Chogin (oval silver coins) were made in Fushimi Ginza (silver mint) and since then, Chogin of a consistent standard had been coined by the Edo bakufu (Japanese feudal government headed by a shogun) and after the Genwa era, Mameitagin (small coins) of the same quality were made as a permanent small currency unit.
慶長6年（1601年）には、伏見銀座から慶長丁銀が鋳造され、以後、江戸幕府によって品位を一定に定められた丁銀が発行され、元和(日本)年間以降は常に小額通貨である同品位の豆板銀（小玉銀）を伴って発行された。
