⅔ Thaler - John George II

John George II ruled Anhalt-Dessau from 1660 until his death in 1693, a period when the fractional Thaler denominations produced by the smaller German principalities were driven largely by trade necessity rather than prestige — the ⅔ Thaler had emerged as a practical settlement coin following the monetary chaos of the Thirty Years' War. The KM#5.2 designation distinguishes this from the earlier die pairing, a distinction that matters to specialists working the Dav SG references for this series.
