Elderly was once one of only two American retailers for Apitius Mandolins, now only sold directly.[18] As part of its consignment business, Elderly sells "collections" of instruments that sometimes have rich histories. In September 2006, it placed the Dopyera family's personal collection of resonator instruments up for sale, including some of the Dobro and National brands.[19] The Dopyera family was responsible for founding those companies and innovating the resonator instrument trade.[20]
