The large, silver-plated owl fibulae were widespread in the territory populated by the Balt tribes (Letgallians, Semigallians and Courlanders) in the second half of the Middle Iron Age (8th and 9th centuries) and were used for fastening men's clothing. Approximately 30 owl fibulae (of them 20 Letgallian owl fibulae) have been found in the present-day territory of Latvia, and some also in Lithuania and Estonia. As the process was rather labour-consuming, outstanding craftsmanship skills were required for producing them. Owl fibulae have been found in the burial grounds of rich persons and could be considered an object of prestige at that time. The vivid artefact of our cultural heritage now adds to the diversity of the range of 1-lats circulation coins.
