About the coin: This 10 Mark gold coin was struck in the Kingdom of Saxony during 1872–1873, following its inclusion in the newly formed German Empire. King John I ruled from 1854 to 1873, a period during which Saxony remained a major cultural and economic center. The coin is made of 90% gold, weighing 3.982 g, which equals 3.5838 g of pure gold. Today, these coins are treasured historical relics marking the early years of the German Empire.
