Back to OP: Queen's Dowry...
I've made a "discovery" that seems to put to rest any rumors about a queen's dowry - don't get mad. I was just following facts. Also, while there are some citations to back it up, they are difficult to verify as they are published in French, Spanish, Italian & other languages because they are compiled from various contemporary letters & writings by Torcy, St. Simon, Alberoni, Ursins & others.
Bottom line...
*"The Duke of Parma...was poor [and] had provided NOTHING" for the queen's journey to reach Spain (after their September 1714 wedding by proxy). This would suggest that if there was a dowry at all, it was small & wiped the Duke out, or more likely, there was no dowry to begin with. They mooched upon Philip's treasury for 3 months with a caravan of about 600 people! (*The Princess des Ursins by Maud Crutwell, 1927)
Elisabetta's true value to King Philip V was as an heir to Parma where she could regain power for Spain over Italian provinces through her offspring.
