The numismatic collections contain more than 195 thousand exhibits: numismatics (coins, ingots), complexes of hidden and lost money (hacked silver, ingots, hoards of coins and paper money, contents of purses), medals, phaleristics (orders, award medals and badges), philophaleristics (badges) and other kind of badges, notaphily, tokens and counters, telephone, bank, discount and other cards, lead seals, as well as exhibits reflecting the production of the aforementioned objects (sketches, draft designs, models, seals etc.). It is the largest numismatic collection in Lithuania covering the period from Classical Antiquity until our days.

Objects related with Lithuania are purposefully collected. The material is presented in the museum’s thematic exhibitions, published in the museum’s chronicle Numismatics, Lithuanian and international publications, and presented in scientific conferences. Two conferences dedicated to numismatics were held at the National Museum of Lithuania in 2006 and 2012.

On the basis of the numismatic collections, virtual exhibitions of numismatics of the Grand Duchy of Lithuania (GDL), coin finds, the symbol of the Knight on the coins of the GDL, symbols of Christianity on the earliest coins of the GLD, contemporary state awards of Lithuania, religious medals with images of Jesuit saints, badges of Lithuanian sports from the 1920s and 1930s, and badges of Lithuanian organisations from 1918–1940 from Algimantas Astikas’s collection have been staged.
