however , there is no evidence that it was widely distributed , so it cannot be said for sure that fuhonsen coin is the oldest circulating money . しかし、広く貨幣として流通していた証拠は未だに無く、富本銭が最古の流通貨幣であると断言することはできない。
all the currency issuances in the history of japan was circulating money and there is no record referring to those of incantation coin for religious purpose . 日本の歴史上に残る貨幣発行は全て流通貨幣であり、厭勝銭という宗教的な目的の貨幣発行を示す記録はない。
in stead of imported bronze coins , eirakusen , from the ming dynasty , the shogunate government established the coinage guild to mint domestic coins such as kanei tsuho coin for the circulating money in the country . そして輸入品であった永楽銭などに代わり、銭座を設けて寛永通宝などの国内貨幣を鋳造し、流通させた。
there is no record of an act that prohibits shichusen (counterfeit money ) just after the issue of fuhonsen coin , and such act was first established only after the issue of wado-kaichin , which means shichusen was allowed if fuhonsen coin was circulating money . 富本銭発行直後に贋金（私鋳銭）を禁じる法令が出されたとする記録がなく、その最初の例が和同開珎発行後であること（もし、富本銭が流通貨幣ならば、贋金の存在を放置していたことになる）。
