⅙ Thaler - Frederick William III Mint Visit

Frederick William III's 1819 mint visit to the Berlin facility was commemorated with a small series of struck pieces, of which this sixth-thaler is the most modestly denominated. The visit itself came during a period of significant monetary reorganization in Prussia — the kingdom was still rationalizing its coinage system in the years following the Napoleonic disruptions, and the king's personal inspection of the mint carried genuine administrative weight, not merely ceremonial.
