1/4 Thaler

Regensburg's status as a Free Imperial City gave it the right to mint its own coinage, a privilege jealously guarded throughout the Holy Roman Empire's final century. The city was also the permanent seat of the Immerwährender Reichstag — the perpetual imperial diet that sat continuously from 1663 until Napoleon dissolved the Empire in 1806 — making it one of the most politically active minting authorities of the period despite its modest size.

The thirty-year span of this type almost certainly reflects die reuse rather than continuous fresh production, a common economy among smaller imperial mints.
