This specific motto belongs to a famous family of Protestant coinage known as Jehovah Thalers (or Jehovataler in German), which were minted primarily by the Silesian Evangelical Estates (based out of modern-day Wrocław, Poland, then known as Breslau).

The Historical Context: These coins were struck during and shortly after the tumultuous Thirty Years' War (1618–1648). Protestant states and principalities prominently displayed the name of God in Hebrew script or Latin (IEHOVA) to make a bold religious statement against the Catholic Holy Roman Empire.

The Design: On the reverse side of the coin, you will typically see the name IEHOVA surrounded by bursting sun rays and clouds (representing the Divine presence), towering over a crowned coat of arms or a Silesian eagle. The motto SALVS ET VICTORIA NOSTRA wraps around the outer edge.The Latin phrase "Salus et victoria nostra" translates directly to English as "Our salvation and victory" or "Our health and victory." Giving credit to Jehovah.

The eagle confirms that your coin is from the Silesian Evangelical Estates (or Evangelischen Stände in Schlesien), minted in Wrocław (Breslau), which is in modern-day Poland.The coin you hold is a legendary Protestant piece of emergency currency from the mid-17th century.
