Papal states coin valuation.

https://en.numista.com/catalogue/pieces3612.html

I recently picked this up for free from my local dealer. I tried to find the value of it using NGC but can't have selected the correct Papal State and thus, received no information. Some assistance would be useful!

Would also like to know if my coin is genuine?
