Wilhelm I (1861-1888) was a great ruler, who united many small German states into the mighty Empire in 1871. He was rather popular in Russia, because he was an adherent of peace between our Empires. Well.. Wilhelm the First was a wise ruler... 1. Coronation thaler 1861, silver .900, weight - 18,52 g., mintage - 1000000. 2. Thaler 1871, "Victory over France", silver .900, weight - 18,52 g., mintage - 880000.
Post-reforming Prussian coin: 5 mark 1876, silver .900, weight - 27,777 g., mintage - 2098000. Wilhelm I the King & Emperor.
Wilhelm II (grandson of Wilhelm I) was a ruler of Germany in 1888-1918. He was a relative of Nicolas II (russian Emperor during 1894-1917). But in 1914 Germany was involved in WW I and in 1918 the Second Reich fell... And Russian Empire fell too..

A couple coins yet. 1. 3 mark 1913, silver .900, weight - 16,667 g., mintage - 2000000. "25th Anniversary of reign". 2.3 mark 1914, silver .900, weight - 16,667 g., mintage - 2564000.
This couple devoted the Centennial of Napoleon"s defeat. 1. 3 mark 1913, silver .900, weight - 16,667 g., mintage - 2000000. 2. 2 mark 1913, silver .900, weight - 11,111 g., mintage - 1500000.
2 mark 1913, silver .900, weight - 11,111 g., mintage - 1500000. Wilhelm II, "25th Anniversary of reign" .
That "pattern" is somewhat odd in my opinion. Such 5 mark coins were not issued by the Empire but by the single states. So a piece depicting Wilhelm II should also have his title as king of Prussia, which I don't see here. And the side with the "face value", well, that eagle looks too cartoonish to me, but of course YMMV ... Christian
