When a large number of copper coins were carried, it was common that a set of 1000 coins was bundled up with a string at their center holes for convenience of a carry and count and there existed a simpler version of a set of 960 coins, called tanhaku.
大量の銭を持ち歩く際、持ち運びやすく数えやすいように、銭の中央に空いている穴に紐を通して（貫いて）1000枚を1組としておくということがよく行われた（短陌の場合は960枚）。
