DeBence Antique Music World is a museum in Franklin, Pennsylvania whose collection contains more than 100 antique mechanical musical instruments, including music boxes, band organs, player pianos, a nickelodeon piano, as well as a number of other antiques. Many of the collection's mechanical instruments are rare; a number are among only a few manufactured, and a few are among the last in existence. Although the collection's value cannot be measured, an offer for a sum of multiple millions of dollars was once rejected.
