Hilfe für faire Wertermittlung

Was sollte ich dafür bekommen fairer Weise ? 

What is the weight and diameter?

Is the picture accurate? From the images it doesn't look like gold. There's a lot of wear on the P in Pistole – that's not how I would expect a gold coin to be treated.

It’s 220 years old, i think the coin is really good for this age

Start with verification of gold content and authenticity. For a coin that is supposed to be .900 purity, it does have a rather brassy look to it. Then start at melt value. It is worth what somebody is willing to pay for it.
