Interesting fact

The 1 Duit coin from the City of Utrecht was made of copper, which was a common material for coins during that time period. However, what makes this coin stand out is that it features a unique design element - a small hole in the center of the coin. This hole was intentionally placed there by the mint masters as a way to test the authenticity of the coin. If the hole was not present, it was considered a counterfeit coin. This feature is known as a "proof mark" and was used by mints during that time to ensure the authenticity of their coins.
