Dollars issued since 1990 have the words "The United States of America" around the central portrait of the president, visible only through a magnifying glass. Another protection is the number of banknotes written with 10-15 micron polyester thread. Also, 97% of circulating US dollars have traces of cocaine, which is due to the fact that drug trade is done in dollars. Mostly 5, 10, 20, 50 dollar bills are affected. However, because cocaine is deeply embedded in the dollar, it does not affect human hands. US dollars have a maturity of 22 months for $1, 16 months for $5, 18 months for $10, 24 months for $20, 55 months for $50, and 89 months for $100. In 1861, when the US Congress issued an order to print $60,000,000, the money was printed in green because the printing press had an excess of green dye. The dollar is a very strong currency. It can be bent and stretched 4000 times. The $1 bill features a topless pyramid, part of the US Great Seal, with the words Annuit Coeptis, meaning "He has blessed us," in Latin above, and Novus Ordo Selcorum, meaning "The Order of the New Era," below. At the unfinished top of the pyramid is the Masonic symbol of the All-Seeing Eye, which is attributed to the Masons of the first president, George Washington, and Benjamin Franklin, one of the authors of the Declaration of Independence. But it is officially explained that the pyramid is the base of development and the symbol of pyramidal power, and the fact that it does not have a top shows the necessity of work for further development. The $2 bill was last printed in 2003. Although the dollar is called America's paper currency, it is not actually made of paper. Made of 75% cotton and 25% linen woven with very fine silk threads. That's right, it turns out that a dollar forgotten in a jeans pocket can withstand more than one wash. Also, the dollar bill has never featured portraits of black American politicians or social figures, but in the 1940s, portraits of only a handful of famous people in science, culture, and sports were printed on coins.
