1 Guldengroschen 'Joachimsthaler'

The Schlick family began striking these large silver pieces at their mine in Joachimsthal, Bohemia, from 1519 onward — an act of seigneurial privilege that irritated the Habsburg administration considerably. The coins proved so commercially successful and so widely imitated across the German states that the Joachimsthaler name contracted, eventually, into "thaler," the root from which both the Dutch daalder and the Spanish-American dollar descend.

The Schlicks lost control of the Joachimsthal mint in 1528 when Ferdinand I of Habsburg revoked their mining rights and absorbed the operation directly into royal administration. Pieces struck in the 1523–1527 window are therefore among the last privately issued examples before that forced transfer.
