Menzel: BBBInteresting fact
One interesting fact about the 10 Pfennigs - Mettmann coin is that it was made of iron, which was a unusual choice of material for coins at the time. Most coins were made of precious metals like gold, silver, or copper, but the 10 Pfennigs - Mettmann coin was made of iron, which was a less valuable metal. This choice of material was likely due to the economic conditions of the time, as the use of iron was seen as a way to reduce the cost of producing coins. Despite being made of a less valuable metal, the 10 Pfennigs - Mettmann coin is still a valuable collector's item today, and its unique composition makes it stand out among other coins of its time.
