Cohn & Rosenberger was started by Emanuel Cohn and Carl Rosenberger in New York City around 1901 and started producing and selling highly desirable costume jewlry, eventually becoming the largest costume jewelry company in the United States. In 1913, they incorporated . On June 24, 1943, the company officially changed their name to Coro, Inc. (CO for Cohn, RO for Rosenberger). Cohn & Rosenberger issued their first public stock offering in 1929. Coro had another public stock offering in 1945.
One of the most famous types of jewelry that they created was the Coro Duette, which was a double clip that could be combined into one brooch. They also produced many patriotic jewelry styles, including the Emblem Of The Americas brooch, during World War II (this certificate was issued during World War II).
Richton International Corp. bought out the American division of Coro in 1957. In 1979, Coro, Inc. went out of business.
This stock certificate was issued and cancelled in the 1940's and features the machine printed facsimile signature of Carl Rosenberger. It also has fancy background printing from the Hamilton Bank Note of New York. Very fine condition with the usual staple holes and cancellation holes.
This certificate should be framed and hung on the wall of any jewelry collector.
