California Pacific International Exposition half dollar

California Pacific International Exposition half dollar.
The California Pacific International Exposition half dollar is a fifty-cent piece that was struck by the United States Bureau of the Mint in 1935 and 1936 as a commemorative coin. Its obverse depicts Minerva and other elements of the Seal of California; the reverse shows buildings from the California Pacific International Exposition (held 1935–1936), which the coin was issued to honor. Legislation for the half dollar moved through Congress without opposition in early 1935, and Robert I. Aitken was hired to design it. The San Francisco Mint produced 250,000 coins, but expected sales did not materialize. The Exposition Commission, left with over 180,000 pieces they could not sell, sought and obtained legislation authorizing new coins. Although there was a spike in prices for many commemorative coins in 1936, the Exposition Commission's new coins also sold poorly, and 150,000 pieces were returned to the Mint.
