The story behind the coin
In 1944, the United States invented a rank it had never had before: the five-star general. Only a handful of men ever wore those five stars in a circle — and five of them had passed through the same Army schoolhouse on the Kansas prairie.
That schoolhouse is the U.S. Army Command and General Staff College at Fort Leavenworth. George Marshall, Douglas MacArthur, Dwight Eisenhower, Henry "Hap" Arnold, and Omar Bradley were all alumni or instructors there. In 2010, Congress decided to honor them — and to help the college's foundation — with a set of coins.
The law was the 5-Star Generals Commemorative Coin Act, signed on October 8, 2010 (Public Law 111-262). It authorized three coins, struck only in 2013: a clad half dollar, a silver dollar, and this gold piece — the $5 half eagle. The gold coin belongs to MacArthur alone.
Here is the surprising part. Of the 1.35 million coins the law allowed across all three denominations, collectors bought only about 16 percent. The gold coin sold worst of all. And that failure is exactly what makes it interesting today.
