1809 C German State (possibly Westphalia) ID and Verification

I have what I believe is a German State (possibly Westphalia) silver coin, 1809 C. I am not 100% sure of the location or value. I did not find the coin in the database, and would like to verify its origin and authenticity. Any help is appreciated! Below is the coin.

Welcome to the forums!

I'm not sure if your coin is the catalogue, but your attribution to Westphalia is correct; the monogram "HN" is for Hieronymus Napoleon (or Jérôme Bonaparte), ruler of the French (Napoleonic) puppet state of the Kingdom of Westphalia (1807-13).

It doesn't seem to be in the Numista catalogue at the moment, but for now here's your coin:

As for authenticity, I see no reason to doubt it's real.
