The story behind the coin
The Infantry has a two-word motto, and it is not a slogan a marketing team invented. Follow Me. It is what an officer is expected to say with his body before he says it with his mouth — go first, up the hill, into the fire, and trust that the line comes with you. The 2012 Infantry Soldier silver dollar is that idea turned into metal.
The coin exists because of a building. In 2008 Congress passed the National Infantry Museum and Soldier Center Commemorative Coin Act (Public Law 110-357), signed into law on October 8 of that year. The act ordered the Treasury to strike a silver dollar honoring the legacy of the U.S. Army Infantry — and, just as importantly, to help fund the National Infantry Museum at Fort Benning, Georgia. Each coin sold carried a $10 surcharge earmarked for the National Infantry Foundation, to build an endowment for the museum's upkeep.
That is the quiet machinery behind most modern U.S. commemoratives: a coin is also a fundraiser. You buy a dollar of silver; ten dollars of your purchase goes to a cause Congress chose. The Infantry dollar's cause was the place that keeps the branch's history — and its dead — from being forgotten.
