Interesting fact

One interesting fact about the Standard circulation coin 1 Mon "Kan'eitsūhō" (Copper alloy; 小 "Ko" reverse) ND (1737-42) from Japan made of Copper weighing 2.39 g is that it was issued during a time of great economic change in Japan. The Kan'eitsūhō coin was introduced in 1737 as part of a new currency system aimed at combating inflation and stabilizing the economy. The coin was made of copper, which was a more affordable material than the silver or gold used in previous coinage, and it was designed to be easily recognizable and difficult to counterfeit.
