The $1 bill carries George Washington’s portrait on the front and the Great Seal of the United States on the reverse. Unlike higher denominations, it has not received modern color or advanced security features, making it iconic but more vulnerable to counterfeiting.

The $5 bill portrays Abraham Lincoln on the front and the Lincoln Memorial on the reverse. It incorporates two watermarks and a security thread that glows blue under UV light.

The $10 bill shows Alexander Hamilton, the first U.S. Treasury Secretary, on the front. The reverse highlights the U.S. Treasury Building. This note includes subtle background colors of orange, yellow, and red.

The $20 bill features President Andrew Jackson on the front and the White House on the reverse. It is the most widely used note in ATMs across the U.S.

The $100 bill is the largest denomination in regular circulation. It features a portrait of Benjamin Franklin on the front, with Independence Hall on the reverse. Modern security features include a blue 3D security ribbon and a color-shifting bell in an inkwell.

The 1996 series of the US 100 dollar note introduced the “Big Head” portrait of Benjamin Franklin, marking the first major redesign in nearly 70 years. The note featured enhanced anti-counterfeiting features including a watermark, security thread, and color-shifting ink. The reverse retained the image of Independence Hall. This design was later replaced by the 2013 blue security ribbon series.
