San Francisco–Oakland Bay Bridge half dollar.
The San Francisco–Oakland Bay Bridge half dollar is a fifty-cent piece struck by the United States Bureau of the Mint in 1936 as a commemorative coin. One of many commemoratives issued that year, it was designed by Jacques Schnier and honors the opening of the Bay Bridge that November. One side of the coin depicts a grizzly bear, a symbol of California, and the other shows the San Francisco–Oakland Bay Bridge, with the Ferry Building. Congress passed authorizing legislation for the coin in 1936. Schnier's models were approved and the coins were struck at the San Francisco Mint. Just over 70,000 coins were sold, by mail, in person, and from booths at the Bay Bridge's approaches, making it the first commemorative coin to be sold on a drive-in basis. The coins were taken off sale in February 1937, with the unsold remainder returned to the Mint for redemption and melting. The Bay Bridge half dollar catalogs in the low hundreds of dollars, depending on condition.
