The Civic Archaeological Museum of Ozieri preserves in the numismatic section part of the three monetary treasures of Lagostis (1868), Baesia (1875), Tramentu (1894). Other discoveries of the 20th century, those made by the notary Biddau at the end of the 19th century in a rustic Roman building, arrived at the Museum partly as a gift and partly for purchase from the Amadu collection.
The Cattina bronze collection and the Delogu-Tola ingot, also acquired by the Museum with regional and municipal funds, are among the most important testimonies of the Bronze Age.
