Interesting fact

The 12 Mariengroschen coin was minted during the reign of John Frederick, Duke of Brunswick-Lüneburg-Calenberg, who was a prominent figure in the German States during the 17th century. The coin's design features the duke's portrait on one side and the coat of arms of the Brunswick-Lüneburg-Calenberg family on the other. The coin was made of silver and weighed 6.75 grams, which was a significant amount for a circulating coin at that time. Despite its age, the 12 Mariengroschen coin remains a popular collector's item among numismatists today, with some rare examples selling for high prices at auction.
