A glossary linked to the exhibition will help students learn challenging vocabulary.&nbsp;History, at times, gives certain objects special significance, and they become legendary. Unlike money that changes hands daily, legendary coins and currency are larger than life,<strong> </strong>and tell a unique history of the United States.<strong>&nbsp;</strong><em>Legendary Coins and Currency </em>shows<em> </em>how major events in the nation's history have played a role in the evolution of America's money and determined how a select few pieces of currency have become important symbols of the American experience.<strong></strong></p>Mon, 14 May 2012 11:55:25 GMT
