Thank you all. My next question was about proper cleaning. Is there a thread dedicated to cleaning coins??
Real nice coin, I've been detecting in Germany for 25 years and have not found one of those, I did find a gold coin from the same King, Wilhelm II. Some say King Wilhelm II was the biggest instigator of WWI, he was banished from Germany after the war. My book says 6.34 million were made, .900 silver, 16.67 grams. I wouldn't clean it, just rinse it off with water and a soft brush. Congrats and HH, Mike
