The numismatic collection of the National History Museum - Sofia contains over 60 different monuments - coins, banknotes, stamps, draw weights, scales and others.

The main part is the coins, both collective finds (coin hoards) and single specimens. The collection contains monetary tokens used in commercial exchange even before the coins were found, the so-called "domonetic forms of money" as well as multi-faceted ancient and medieval coins. Coins from the new and most recent times, up to the present day, are also presented. The part of the seals consists mainly of Byzantine and Bulgarian medieval seals (molyvdovuli), representing primary historical sources for studies in the field of medieval history. Metrological monuments are various draw weights and balances used by seraphs in Antiquity and the Middle Ages in their activities related to the measurement of coin weights.

The diverse composition of the materials stored in the collection makes it possible to display in the halls of the museum a significant number of cultural and historical monuments from different historical eras, which will illustrate the development of monetary circulation and the great variety of coin circulation in today's Bulgarian lands over the past three millennia. In addition, these materials, in their capacity as full-fledged historical sources, serve as a basis for numerous and most diverse scientific studies in the fields of history, archeology, numismatics, spragistics, etc.
