50 Kopecks Latvia, Libava, Libau

Libau's 1915 emergency issues emerged from a specific administrative collapse: as German forces advanced through Courland in the spring of 1915, the Russian imperial monetary system simply stopped functioning in the western Baltic provinces. Local municipalities were left to fill the void themselves. Libau fell under German military occupation in May 1915, meaning these city-issued kopeck notes had an extraordinarily brief window of legitimate circulation under their original issuing authority.

The unlisted status in Pick reflects a broader documentation gap for Baltic municipal notgeld of this period — many issues were small-run, locally distributed, and rarely preserved.
