Vintage collectors will pay up to $4,000 for a mint-condition, vintage RCA Victor Radio. The Radio Corporation of America, as you might have guessed from the name, was the maker of radios in the 1920s. RCA was responsible for tons of innovations in radio tech, and it made every radio imaginable.

Whether you were looking for a military radio or radiotelephone, RCA could make it. Though now, the technology seems practically primitive, it was cutting-edge at the time. The Radiola, which debuted in 1922, is one of the more valuable RCA brands when it comes to vintage re-selling.
