The Ernst Badian Collection of Roman Republican Coins is housed at the Special Collections and Archives department of the Rutgers University Libraries.

The collection is composed of more than 1200 coins documenting the emergence of coinage and a money economy in Rome and developments down through the late Republic (280 to 31 B.C.E.). Classics Professor T. Corey Brennan was instrumental in securing the donation of Dr. Badian's collection to the University.
