Beeskow, a small Brandenburg town on the Spree, issued emergency copper coinage during the currency chaos of the early Thirty Years' War, when the Kipper und Wipperzeit — the great debasement crisis of 1619–1623 — had so thoroughly destroyed confidence in circulating silver that municipalities across the German lands resorted to local copper issues simply to keep markets functioning. At 13 grams for an 18mm piece, this pfennig is strikingly heavy relative to its face value, reflecting copper's role as a fallback rather than a precisely calibrated monetary instrument.
