25 Schilling Franz Lehar

Austria's long-running silver commemorative schilling series regularly honored composers, and the 1970 Lehár issue marked the 100th anniversary of the composer's birth. Franz Lehár spent much of his career in Vienna but was born in Komárom, then part of the Austro-Hungarian Empire — a fact that complicated his cultural ownership between successor states for decades. His operetta Die lustige Witwe achieved a global reach unusual even by Viennese standards, reportedly earning more performances in a single decade than any competing work in the genre.

The .800 fine silver specification was consistent with Austria's commemorative output of this period, chosen to keep production costs manageable while maintaining a silver identity.
