10 Gulden - Frederick Charles of Schönborn

Frederick Charles von Schönborn held the unusual distinction of ruling simultaneously as both Prince-Bishop of Würzburg and Prince-Bishop of Bamberg from 1729 until his death in 1746 — a personal union that concentrated enormous ecclesiastical and secular power in a single figure across two of Franconia's most important territories. The 10 Gulden pieces struck at Würzburg in 1735–36 fall within his most ambitious phase of patronage, when he was pouring resources into Balthasar Neumann's ongoing construction of the Würzburg Residenz, one of the great Baroque building projects of 18th-century Germany.

The Schönborn family's coin issues from this period are notoriously difficult to attribute precisely — dies were sometimes shared or reworked across minting years, and Helmschrot's enumeration does not always align cleanly with Krug's Bamberg references for related types.
