An image of the first U.S. President (1789 -- 97), George Washington, based on a painting by Gilbert Stuart, is currently featured on the obverse (front), and the Great Seal of the United States is featured on the reverse (back). The one - dollar bill has the oldest overall design of all U.S. currency currently being produced (The current two - dollar bill obverse design dates from 1928, while the reverse appeared in 1976).

paragraph_text: The early currency of the United States did not exhibit faces of presidents, as is the custom now; although today, by law, only the portrait of a deceased individual may appear on United States currency. In fact, the newly formed government was against having portraits of leaders on the currency, a practice compared to the policies of European monarchs. The currency as we know it today did not get the faces they currently have until after the early 20th century; before that "heads" side of coinage used profile faces and striding, seated, and standing figures from Greek and Roman mythology and composite Native Americans. The last coins to be converted to profiles of historic Americans were the dime (1946) and the Dollar (1971).

paragraph_text: The crisis started in Thailand (known in Thailand as the Tom Yum Goong crisis; Thai: วิกฤตต้มยำกุ้ง) with the financial collapse of the Thai baht after the Thai government was forced to float the baht due to lack of foreign currency to support its currency peg to the U.S. dollar. Capital flight ensued, beginning an international chain reaction. At the time, Thailand had acquired a burden of foreign debt that made the country effectively bankrupt even before the collapse of its currency. As the crisis spread, most of Southeast Asia and Japan saw slumping currencies, devalued stock markets and other asset prices, and a precipitous rise in private debt.Indonesia, South Korea, and Thailand were the countries most affected by the crisis. Hong Kong, Laos, Malaysia and the Philippines were also hurt by the slump. Brunei, China, Singapore, Taiwan, and Vietnam were less affected, although all suffered from a loss of demand and confidence throughout the region. Japan was also affected, though less significantly.

paragraph_text: This was meant to be a temporary measure, with the gold price of the dollar and the official rate of exchanges remaining constant. Revaluing currencies was the main purpose of this plan. No official revaluation or redemption occurred. The dollar subsequently floated. In December 1971, the ``Smithsonian Agreement ''was reached. In this agreement, the dollar was devalued from $35 per troy ounce of gold to $38. Other countries' currencies appreciated. However, gold convertibility did not resume. In October 1973, the price was raised to $42.22. Once again, the devaluation was insufficient. Within two weeks of the second devaluation the dollar was left to float. The $42.22 par value was made official in September 1973, long after it had been abandoned in practice. In October 1976, the government officially changed the definition of the dollar; references to gold were removed from statutes. From this point, the international monetary system was made of pure fiat money.
