5. The unlikeliest Kennedy coin

What must the yak-herding descendants of Genghis Kahn have thought when they first encountered the 2007 Mongolian 500 Tugrik coin, flipped it over and discovered President John F. Kennedy on the tails side?

Much less when they pressed a tiny button on JFK's chest and heard an actual sound bite from his famous "Ich bin ein Berliner" speech? Chances are we'll never know, since collectors quickly snatched up most of the oddities, which may have been the sole reason for printing them in the first place. Nevertheless, Kennedy is well beloved in Mongolia for launching the Peace Corps.
