The Bay Bridge Half Dollar: a coin you could buy without leaving your car

For sixty years, people had dreamed of a bridge across San Francisco Bay and given up. The water was deep, the distance enormous, the engineering beyond reach. Ferries did the job instead — they had crossed the bay since 1851, slow and crowded.

The Great Depression, oddly, is what finally built it. Federal money flowed through the Reconstruction Finance Corporation to buy the construction bonds, and the San Francisco–Oakland Bay Bridge rose across the water in the early 1930s. When it opened on November 12, 1936, it was the longest steel high-level bridge in the world, and the city celebrated for three days straight.

Congress wanted a coin for the moment. President Franklin Roosevelt signed the authorizing act on June 26, 1936, clearing the way for up to 200,000 commemorative half dollars to mark the opening. The money raised would help pay for the celebration itself. Only the San Francisco Mint would strike them — so every coin carries an "S" mint mark (the small letter that tells you which mint made a coin).

The job went to Jacques Schnier, a local artist with an unusual résumé. Born in Romania in 1898 and raised in San Francisco, he had trained as an engineer at Stanford before turning to sculpture and teaching it at UC Berkeley for thirty years. The Bay Bridge half dollar would be his only coin.

The obverse — the "heads" side — is pure California: a grizzly bear, the animal on the state flag, standing alone with "LIBERTY" at its feet. Schnier's initials, "JS," sit to the right; the "S" mint mark to the left. The bear stirred a small fuss at the time — critics argued a bear didn't exactly embody Liberty — but it stuck.

Turn the coin over and you get the view that mattered. The reverse looks west across the bay toward the bridge from the San Francisco side: the Ferry Building in the foreground, Yerba Buena Island in the middle, the Berkeley Hills behind, and on the water a ferry boat and an ocean liner — the old way of crossing and the world the bridge connected to. Schnier packed so much into the scene that the engravers complained there was barely a flat spot left on the coin. The art historian Cornelius Vermeule later compared its sweeping perspective to Renaissance medals.

One thing you won't find on it: Treasure Island, the man-made island built for the 1939 world's fair. It simply didn't exist yet when the dies were cut.

This is one of the more attainable classic U.S. commemoratives, and the drive-in booths are the reason. There is only one date and one mint — the 1936-S — so there are no rare varieties to chase. With more than 71,000 sold to the public, survivors are plentiful, and you can own a respectable example without a fortune.

The catch is condition. Because so many were bought as souvenirs by motorists rather than carefully preserved by collectors, plenty got knocked around. The grizzly's high points and the busy bridge scene show wear and contact marks easily. A truly pristine, sharply struck coin in the top grades is far scarcer than the raw mintage suggests — one exceptional specimen brought $21,850 at auction in 2004. For most collectors, a clean uncirculated piece is the sweet spot: common enough to find, beautiful enough to enjoy.

A note on later "issues" you may see: in 1986, a dealer had 1,000 of these coins placed in holders personally signed by Schnier, then numbered and sealed. Those are the same 1936 coins — repackaged decades later as a souvenir of the aging designer — not a new minting.
