The San Diego California-Pacific Exposition Half Dollar was issued in 1935 and 1936 to commemorate the city's exposition during those years.
The legislation stated: "The United States shall not be subject to the expense of making preparations for this recoinage, and such coins shall be issued only to California-Pacific International Exposition Company, or its duly authorized agent, which may dispose of the same at par or at a premium: Provided, That all proceeds therefrom shall be used in furtherance of the California-Pacific international projects."
The obverse design features a composite image of a seated woman, bear, horn of plenty, ship, and a miner at work.
The reverse design features one of the exposition buildings with the name San Diego.
