999 fine silver coin. I tried to do as much research as I could, and I couldn’t even find a picture of another one. I sent pictures to a friend that owned coin store for 10+ years and he had never seen one either, but his educated guess was that the mintage was less than 1000. Covered box is 4″ wide 3 1/2″ tall and 1 thick. SCALE NOT INCLUDED IN THE SALE. Total weight shown includes the plastic protector. If you have any other questions feel free to ask. PLEASE CHECK OUT MY OTHER COIN LOTS. Arrived quickly as pictured. Item was packaged very well. Follow me or add me to your Favorite sellers list.
