Before that, of course, since 1846, postage stamps were also issued, but they had no official status. The first us postage stamps had a face value of 5 cents and 10 cents, which depicted George Washington and Benjamin Franklin.

 The difference in nominal value was due to the fact that a cheaper postage stamp of 5 cents paid for letters carried over a distance of less than 300 miles. 10 cents was worth sending the letter at a distance of over 300 miles. There were also differences in the weight of parcels.

In 1893 in the United States held an exhibition dedicated to the 400th anniversary of the landing in America Christopher Columbus. In this regard, 16 stamps depicting Columbus and various episodes from his life were issued. This series of us postage stamps is considered the first series of commemorative stamps in the world. Postage stamps of this series were highly appreciated by collectors, as they are valued to this day.
