1 Poltura- Maria Theresia Hall

The poltura was a low-denomination billon coin inherited from Hungarian monetary tradition, and its continued production under Maria Theresia reflected the administrative patchwork of Habsburg currency — different denominations, different alloy standards, different minting authorities operating simultaneously across the hereditary lands. Hall in Tirol, one of the oldest and most technically capable mints in the Habsburg system, handled this issue for just three years before the denomination was effectively retired from the Austrian minting program.

The .243 fine silver content places it firmly in the degraded billon range typical of small-change policy across mid-18th century Central Europe, where governments deliberately kept fiduciary coins cheap to produce relative to face value.
