How does a US dollar look like?

A U.S. dollar bill features a distinct design, primarily green and white, with portraits of notable figures. The front of a $1 bill prominently displays George Washington, while higher denominations feature figures like Abraham Lincoln ($5), Alexander Hamilton ($10), Ulysses S. Grant ($50), and George Washington again on the $100. Each bill also includes intricate patterns, security features, and serial numbers. The reverse side showcases various symbols and historical scenes related to American heritage.
