at this conference , the collection of counterfeit coins of japanese citizens (centered around nibukin ) and the introduction of the modern currency system were decided as international commitments . この会談で日本が官民の（二分金を中心とした）贋貨の回収と近代貨幣制度の導入を国際公約とすることになった。
in order to prevent government officials counterfeiting coins in order to obtain ikai (court rank ), any person who manufactured counterfeit coins was punished with removal of official rank and ' zan ' (execution by decapitation ). 役人が位階獲得を目的に私鋳銭を製造しないよう、私鋳銭製造に対しては官位剥奪、「斬」（首を切る極刑）の罰が加えられた。
however , the amount by the exchange in equal value for foreigners was 340 thousand ryo as mentioned above , and the amount by the exchange following the edict of daijokan , which had become clear was 1 .57 million ryo , while the amount of the bad quality gold coins (actually counterfeit coins ) issued by the government , which is recognized today is 3 .81 million ryo , so the former ones are much smaller than the latter . だが、前述の外国人に対する等価引換が34万両、太政官布告による引換が判明分だけで157万両であり、現在判明している政府発行の悪質な金貨（事実上の贋貨）が381万両であるから、それよりも遥かに少ないことになる。
