In 1847, the United States Post Office Department printed its first stamps, a 5-cent stamp picturing Benjamin Franklin and a 10-cent stamp picturing George Washington.
  That could be a problem, because US stamps go back to about 1847.   Let us assume you have a mint (never used) 15 cent stamp that was  issued in 1893 as part of the Columbian Exposition and stuck it on  a envelope, you just lost $224.85. Oops! The same stamp never  hinged catalogs for $700.or regular-size and regular-weight letters, a safe bet is always that 3 US stamps will get the letter to its international destination. To calculate specific postage, check the website of the USPS -- the United States Postal Service (see Related Link).
