MASZCZYK collection's KM-24 part is a unique collection of over 6,000 Polish coins from the 18th century to the present day. This part of the larger MASzCZYK collection includes rare coins from the Russian Partition, the Polish–Lithuanian Commonwealth, and Great Sejm of the Commonwealth. The coins in the collection demonstrate the emergence of a young and modern Polish nation as it gained its independence in the 19th century and its political, economic and cultural advancement in the 20th century. This collection contains some of the oldest coins of the Republic of Poland (1918–1939), as well as pieces from many eras of the People's Republic of Poland until the modern period. The KM-24 part of the collection also houses coins from the Free City of Danzig, Kraków mints, and coins from modern independent Poland. Notable items in KM-24 include the Warszawa Cossack Hetman coin from the 18th century, a 1927 Free City of Danzig chain coin, a 1951 silver 20 groszy coin, and a 1952 gold 10 zlotych coin.
