Sweden, Gustav IV Adolf (1792 – 1809). ½ Skilling 1803. Overstruck on a 1 Öre SM copper coin. Distinct traces of the undertype are visible beneath the later design, most notably around the legends and rims. Additionally, the coin shows a double striking, giving it a clearly shifted detail on both sides. Such minting anomalies are extremely rare and highly sought after among specialists in early-19th-century Swedish copper issues. Rarity: XRR – extremely rare overstrike and double strike combination. Metal: Copper Weight: 14.2 g Diameter: 30.5 mm. Dark-brown patina, well-preserved for the type
