Ferdinand III inherited the Thirty Years' War from his father and spent the first decade of his reign prosecuting it to exhaustion, signing the Peace of Westphalia in 1648. The Graz mint operated under Styrian provincial authority throughout this period, producing thalers that circulated as war finance moved through the Habsburg hereditary lands. The references cover multiple die pairings across the six-year span — Her#397 and Her#403 denote distinct obverse or reverse die marriages, and buyers should confirm which variety they hold before cataloging.
