The Orsetti House Museum has over three thousand three hundred numismatic items. Particular attention should be paid to the coins of the Roman Empire, Polish crown groszes and half groszes, silver coins from Łobżenica, groszes from Gdańsk and Elbląg, three-grosz coins, quarter thalers, small silver coins, and Austrian coins. There is also a small but valuable collection of Jarosławian regiment badges, medals and badges from World War I, bank notes and the seals of communities from Jarosław and from the vicinity of Jarosław.
