1751 German State-Wurzburg Schilling (6 Nue Pfennig) KM#338

Hello,

Looking for some advice on this coin:





Have been searching for quite a while now on the value of this coin and have found barely anything to compare it to. For instance, NGC has absolutely no price or population:

PCGS only has one in their population report:

And this was the only other sale I could find on the internet:

Worst part is, the 1701-1800 catalogue simply designated the coin as "Rare" and provides nothing at all in terms of price. So, my questions are, would it be worth sending to a TPG, and which one? The coin that sold for $70 in the link above is in about a third of nice as shape as mine and I'm imagining the value would skyrocket around VF+ - XF which is where I believe my coin would end up.

Also, does anyone else here know a specialist on German State coins I could perhaps reach out to? I have many others just like this that are unidentified in terms of potential value.

Thanks and have a great day
