In 1931, the Port Authority opened two major bridges, the George Washington Bridge on October 24th and the Bayonne Bridge on November 14th. The George Washington Bridge Dedication was a big affair, commemorated with 2 gold medals, silver medals, bronze medals in 2 sizes, as well as a hanging badge.
The dedication was a major political event. The Governor of New York, Franklin Delano Roosevelt, a man with serious Presidential aspirations, was one of the major participants in the ceremonies.
All variants were produced by the Whitehead & Hoag Company of Newark, New Jersey. Except for the gold medal, of which two pieces were struck to be given to the governors of New York and New Jersey, no mintages are reported. A 12in galvano of the obverse is known to exist.
