Coro sterling silver pins make for a fine collection of vintage jewelry.
Coro jewelry was founded in New York by Emanuel Cohn and Carl Rosenberger in 1901/1902 and incorporated in 1913. A factory was established in Providence, Rhode Island in 1911. Coro is a great brand to start a vintage jewelry collection because it was one of the largest producers of costume jewelry of its time.
