1 Kreuzer - Charles I

Charles I ascended the Württemberg throne in 1864, and this kreuzer series ran through the kingdom's absorption into the newly proclaimed German Empire following the Franco-Prussian War of 1870–71. Württemberg retained its monarchy and certain sovereign privileges under the imperial constitution, including the right to maintain its own postal and telegraph system, but its independent coinage was progressively rendered obsolete as the unified mark system took hold after 1871.

The billon composition — barely one-sixth silver — reflects decades of small-denomination debasement across the German states, a practical response to chronic shortages of subsidiary coinage rather than any fiscal crisis specific to Württemberg.
