Because each Chinese coin was of small-value, these coins were valued in a unit of 100 thousand kans (a unit of bundling coins; 1000 coins/kan) (or 100 million coins) in some instances, and most of them were circulated as kansen coins or in their original, bundled, state.
もともと中国銭は少額貨幣だったために多ければ10万貫（一億枚）単位で輸入され、多くは貫銭として束ねたまま流通した。
