Vintage coro pin

Coro fashion costume jewelry has been around since 1901 and is one of the most recognized names. In 1901 Emanuel Cohn and Gerald Rosenberg opened a shop in New York. By the 1920's, Coro was the largest manufacturer of costume jewelry. Coro stopped productions in 1979 when Rosenberg retired. I was given this pin about 10 or more years ago. From a friend that got it from a small antique store. I don't wear it. But it used to be clipped to my visor in my truck.
