1⁄28 Thaler - Henry XXII and Wolfgang George

Stolberg's fractional coinage of the early seventeenth century reflects the county's persistent reliance on joint-rule issues under its divided comital lines. Henry XXII and Wolfgang George governed as co-rulers under the partition arrangements that had fragmented Stolberg authority across multiple branches since the mid-sixteenth century. The 1/28 Thaler denomination was a practical money-of-account fraction tied to north German commercial convention, not a coin designed for prestige.

KM#15 is among the scarcer Stolberg joint issues, minted just before the Thirty Years' War disrupted regional silver production across the Harz foothills entirely.
