National Air Races of 1929, held in Cleveland, Ohio.

It measures about 1 1/4 inches across.

On one side, it features images of planes in flight and the lettering "NATIONAL AIR RACES AND AERONAUTICAL EXPOSITION" as well as "CLEVELAND, O AUG. 24 TO SEPT. 2 1929." In the center is what appears to be a small version of the advertising poster for the air races. The lettering is extremely small but reads "1929 NATIONAL AIR RACES AND AERONAUTICAL EXPOSITION CLEVELAND AUG 4 - SEPT. 2."

On the other side of the coin is the image of a building identified as Cleveland's "PUBLIC AUDITORIUM." Also found on this side is the lettering "OFFICIAL SOUVENIR OF THE AIR CLASSIC OF THE CENTURY." There is also extremely small lettering along the bottom edge showing the maker of the coin was Bastian Bros. Co.
