Beautiful coin, both. Congratulations.
Here is another example of the Würzbug Doppeltaler for weight reference:

This example, per catalogue description, weighs 56,14 grams:
DEUTSCHE MÜNZEN UND MEDAILLEN
WÜRZBURG
Franz Ludwig von Erthal, 1779-1795
Doppelter Konv.-Taler 1786, Würzburg. Prämie. 56,14 g. Dav. 2906; Helmschrott 880.
Prachtexemplar mit herrlicher Tönung. Vorzüglich-Stempelglanz.
It is not the actual weight specification for the coin, but probably very close to that so you get an idea what the coin is supposed to weigh.
