Coins, medals, tokens, monetary treasures, historical tools, old machines, paintings and sculptures, graphic arts and objects d’art testify to centuries-old know-how in an ensemble of 17th- and 18th-century buildings.

The heritage collections of the Monnaie de Paris are kept in two places:

• The Pessac heritage reserve, located in the factory’s production area, houses collections of medals, tokens, jewellery, civil and military decorations, tools historically used for making medals and tokens, coinage tools, hallmarking instruments (punches), decorative cast iron, machines, weighing scales, graphic arts and plasters – some 130,000 objects in total.
• The Médaillier monétaire, which was relocated to the Paris site in 2018, houses coin collections from Antiquity to the present day, from France and abroad, as well as metrological collections – approximately 70,000 coins. Added to this are 26,000 paper money specimens (official and emergency) and graphic arts.

The primary mission of the Musée de la Monnaie de Paris is to promote the institution's collections, in accordance with the statutes of EPIC. It received ‘Musée de France’ certification in 2002 and is required to fulfill its own sovereign missions, namely the conservation, presentation and dissemination of the public heritage assets under its management.

In addition to these primary missions, its scientific staff studies, inventories, collects, digitises, restores and enriches the collections and promotes them to the public via education officers.
