Dollar bills
Currently, dollar bills are manufactured in seven denominations: $1, $2, $5, $10, $20, $50, and $100. These bills are printed by the Bureau of Engraving and Printing, which has two offices in Washington, D.C. and Fort Worth, Texas. All U.S. dollar bills are similar in color and are the same size (156 x 66.3 cm), making them easily interchangeable. The paper of the banknotes is made of 75% cotton and the remaining 25% hemp. [The $100 bill features Benjamin Franklin on the reverse side and Independence Hall on the reverse side; along with the $10 bill, it is the only bill without the president\’s portrait on both sides. The $100 bill costs 14.3 cents to print, and bills of this value circulate for an average of 15 years. 17]
