Interesting fact

One interesting fact about the 1 Groschen coin from the Archbishopric of Mainz is that it was made of Billon, which is an alloy of copper and silver. This was a common practice in the early 19th century, as it allowed for the production of coins with a lower silver content, making them more affordable to produce and circulate. The use of Billon in coinage also made it easier to distinguish between genuine and counterfeit coins, as the unique composition of the alloy was difficult to replicate.
