The coin collection comprises nearly 100,000 pieces, including examples from the main series minted from the 6th century BC to the present. The most important and interesting amongst these are, without doubt, the coins produced in Catalonia, which include many extremely rare and unique pieces. The visit to the Numismatic Cabinet begins with the series of ancient coinage, outstanding among which are those minted on the Iberian Peninsula. These include such important pieces as the coins from the Greek colonies of Emporion and Rhode and the treasure of 897 silver pieces found at the neapolis of Emporion. Dating back to the transition period between the ancient and medieval worlds is the collection of Visigoth coins, including some minted at workshops in Catalan territory, such as Barcino, Tarraco or Gerunda. Practically all the western European kingdoms are represented in the medieval Christian series, although the collections of coins from Catalonia and Aragon are the most notable. They include examples that illustrate, step by step, the historic and economic evolution of these lands. For example, the economic growth that Catalonia enjoyed in the 13th century is reflected in the minting in Barcelona for the first time of silver Peter II Croats. Finally, among the coins minted in the modern and contemporary periods, we should mention particularly those produced in Catalonia during three important historic periods: the Reapers War, the War of the Spanish Succession and the French occupation.
