DID YOU KNOW?
Did you know that the U.S. paper money is not made of paper at all? This is because using paper would cause the bill or the money to tear easily. The U.S. currency is actually fabric, and it is composed of 75 percent cotton and 25 percent linen. Aside from that, it also has a tiny red and blue synthetic fibers in different lengths that are evenly scattered throughout. The ink used for money is also remarkably high-tech since it is traceable, magnetic, and able to change its colors.
Dollar bills are also in green because it is the color most resistant to fading and discoloration. In addition, a bill would take around 8000 folds before it will tear from use. In fact, people would repair torn bills with a simple needle and thread in Ben Franklin's Day. Federal Reserve replaces bills that are too worn or those that have been used excessively with a crisp new version. The life expectancy of a U.S. bill depends on its denomination. A $1 bill is expected to circulate for approximately 5.9 years, while the $100 can survive in the circulation for up to 15 years. Studies also show that an estimate of 94 percent bills is contaminated with bacteria. This is because money circulates and moves from one hand to another for several years.
