1 Penning - Frederik I Visby

Frederik I of Denmark claimed lordship over Gotland through the Danish crown's long-contested grip on the island, and the Visby mint operated under that authority in the early sixteenth century. These fractional silver pieces were struck at weights so slight that die alignment and flan preparation were essentially uncontrollable — Hauberg 131 specimens are rarely found without some degree of off-center striking, a known characteristic of the type rather than a defect unique to any individual coin.
