Obol - Ferdinand III

Ferdinand III spent much of his reign managing the ruinous aftermath of the Thirty Years' War, finally concluded by the Peace of Westphalia in 1648. Hungarian minting during his reign was complicated by Ottoman occupation of the central territories, which confined royal mint operations to a narrow strip of Royal Hungary in the north and west — principally Körmöcbánya, the single most important mint in the kingdom for small silver throughout the seventeenth century.

The obol was the lowest practical silver denomination in circulation, and surviving examples in any condition above heavily worn are scarcer than the reference numbers suggest.
