The Duke of Galliera Collection is one of the most renowned private collections of Portuguese coins in the 20th century. Compiled by the Duke of Galliera (1839‑1905), the collection stands out for the quality, diversity, and historical range of its coins, from medieval to modern issues.

The catalogue Portuguese Coins from the Collection of the Duke of Galliera, published in Lisbon in 1949 by J. Almeida, M. Basto, and L. Piombino, documents and illustrates this significant collection. Coins are arranged according to typological and historical criteria, reflecting the richness of Portuguese numismatics over the centuries.

The book preserves the Duke of Galliera’s legacy and remains a key reference for collectors, researchers, and numismatics scholars, allowing detailed study of one of the most important private collections of Portuguese coins.
