1⅓ Reichsthaler 'Speziethaler' - August Louis

August Louis ruled Anhalt-Köthen for just three years, from 1728 until his death in 1755 — though the principality itself was effectively absorbed into Anhalt-Dessau shortly after. The Speziesthaler denomination, valued at 1⅓ Reichsthaler, was a convention of the Upper Saxon Circle monetary system, aligning local coinage with the Leipzig foot standard established in 1690 rather than the later Prussian Graumannscher Fuß. Köthen's output was never prolific; the court had more prestige than economic weight, and surviving pieces from this reign are correspondingly scarce in the secondary market.
