3 Kreuzers - Johann Christian von Eggenberg Krummau

Johann Christian von Eggenberg inherited the Duchy of Krummau in 1649 and held it until his death in 1710, but his coinage rights were exercised only during this specific window — a relatively brief minting period within a long reign. The Eggenberg family had acquired Krummau from the Habsburgs in 1622 as reward for Johann Ulrich von Eggenberg's political services to Ferdinand II during the upheaval following the Battle of White Mountain. Coin-issuing rights came with the territory, though the dynasty's output remained modest and regionally confined.

KM#52 is scarce in any grade; Krummau never operated a high-volume mint.
