Interesting fact

The 1 Duit coin from the City of Utrecht (Dutch Republic) was made of copper, which was a common material for coins at that time. However, what's interesting is that the coin was designed with a unique feature - it had a square hole in the center, which was known as a "plug". This plug was used to indicate that the coin had been officially tested and verified for its weight and purity. This feature was a pioneering effort in the field of coinage and was later adopted by other countries.
