⅔ Thaler - Anthony Günther II

Anthony Günther II ruled Schwarzburg-Sondershausen during a period when the ⅔ Thaler — the Guldenthaler or "two-thirds piece" — was sweeping through the currency systems of northern and central German states. The denomination emerged as a practical response to the chaos of competing monetary conventions after the Thirty Years' War, and by 1676 it had become the dominant large silver coin of daily commerce across much of the region. Schwarzburg-Sondershausen was a tiny, landlocked county with almost no independent monetary muscle, yet its counts struck aggressively to assert comital dignity through coinage.
