In 1878, Edward Muybridge and former California governor, Leland Stanford, busted the myth that a galloping horse kept at least one hoof on the ground at all times. Muybridge, a photographer, set up twelve cameras on Stanford’s horse track in Palo Alto to capture a horse’s gallop as it passed. The photographic evidence showed that at one point, all of the horse’s hooves were airborne. Many believe, though there is little proof, that Stanford had bet $25,000 on the outcome. Could this 1878 Morgan dollar, minted in San Francisco, have been part of the fabled bet?
