10 Euros Carinthia, Silver

Austria's nine-province commemorative silver series, launched in 2004, assigned each federal state a dedicated issue. Carinthia's 2012 entry came at a politically charged moment — the province had spent years in a bruising legal and political battle over bilingual topographical signs in Slovene-speaking municipalities, a dispute rooted in the 1955 State Treaty obligations Austria had quietly ignored for decades. A constitutional settlement was finally reached in 2011, just a year before this coin was struck.

The .925 fineness used across this series is slightly below the more common .999 or .900 standards, a specification chosen to improve die life during minting.
