On the other hand, as one Tenpo-tsuho coin was converted as eight rin (one Kanei-tsuho coin was one rin) in the new monetary system, it is said that people who were way behind the times or people who did not have ability to do so were sometimes cynically called 'Tenpo sen.'
その一方で、新通貨制度では天保通宝一枚＝8厘（寛永通宝一枚＝1厘）と換算されたために、新時代に乗り遅れた人やそれに適応するだけの才覚の足りない人を揶揄して「天保銭」と呼ぶ事もあったという。
