I was about to enter my coin, 5 soldi 1811 from the Kingdom of Napoleon (C# 5) in Krause. Looked hard in the Italian section and I cannot find it anywhere. Does this state go by any other name?

But if yours is in better shape than mine you can still change the picture, don't really know were my coin got its scars if it's official like on many Austrian silver coins of that time or more likely aftermint damage
