Interesting fact
One interesting fact about the 1 Mon "Kan'eitsūhō" coin from Japan is that it was made of iron, which was a unusual choice for coins at that time, as most coins were made of precious metals like gold, silver, or copper. The use of iron in coinage was seen as a way to reduce the cost of production and make currency more accessible to the general population.
