1 Thaler - Frederick III

Frederick III inherited Gottorp in 1616 and spent much of his reign navigating the catastrophic pressures of the Thirty Years' War, which had turned the Holstein borderlands into a corridor for Swedish, Danish, and Imperial troop movements simultaneously. His thalers from this four-year window were struck while Danish royal authority was actively encroaching on Gottorp's administrative autonomy — a dispute that would not be resolved until the 1658 Treaty of Roskilde handed Frederick III of Denmark a humiliation and Gottorp a measure of breathing room.

Davenport's attribution EC II#3700 groups several die marriages across the 1634–1637 span without distinguishing annual emission volumes, so individual date examples carry meaningfully different survival rates.
