DHJ# 4.117 was cast by the people (but apparently not illegally), which explains the poorer worksmanship

Interesting fact

One interesting fact about the 1 Mon "Kan'eitsūhō" coin from Japan is that it was issued during a time of great economic change in the country. The coin was minted during the Edo period, which saw the rise of a strong centralized government and the development of a robust economy. The coin's design, featuring a copper alloy and a "Sa" reverse, was meant to symbolize the country's growing prosperity and economic power. Despite its small denomination, the 1 Mon coin played an important role in the everyday transactions of Japanese citizens during this time.
