This episode set the tone for future offerings of this and other "serial" commemoratives of the mid-to-late 1930's. With nothing to prevent further issues of the Boone halves, new editions were put out annually in three-piece sets through 1938. Both prices and ordering options varied from year to year, creating much confusion and resentment. Congress finally put an end to this abuse in 1939 with the passage of a bill prohibiting the further minting of any commemorative coins authorized prior to that date.
