However, some paper money issued by clans or Hatamoto in the northern part of Kyushu had a distinguishing feature not found in other areas, in which an exchange rate between gin (silver) coins and zeni coins was explicitly written on the surface (for example: 7-sen and 10-monme indicated that the coins of 70 mon should be given for 1 monme, and therefore, this paper money could be exchanged to coins of 700 mon).
しかし、九州北部諸藩・旗本発行の札は、予め銀-銭の交換比率を札面に明記している（Ex.七銭拾匁：一匁あたり七十文で引き換えるという意味で、700文に兌換するという表示）という他地域とは異なる際立った特徴を持つものがある。
