Overview

The $1 bill is the lowest-denomination banknote in the United States currency system, officially known as the United States dollar note. It features a portrait of the first U.S. President, George Washington, on the front, making it one of the most iconic pieces of currency in the world. The $1 bill serves as the foundation of American paper money and plays a critical role in everyday commercial transactions across the nation.

Unlike common misconceptions, the $1 bill is not made from paper but rather from a specialized blend of 75% cotton and 25% linen, which gives it its distinctive texture and durability. Each note weighs approximately 1 gram and measures 6.14 inches by 2.61 inches. This unique composition allows the currency to withstand extensive handling and folding without deteriorating as quickly as traditional paper would, ensuring longevity despite its low denomination value.

How It Works

The $1 bill features multiple sophisticated security measures designed to prevent counterfeiting and ensure authenticity:

Security Thread: An embedded plastic security thread runs vertically through the note, containing text that reads "THE UNITED STATES OF AMERICA" and is visible only when held up to light.
Microprinting: Tiny text is printed throughout the bill, including around the portrait, that requires magnification to read clearly and is nearly impossible for counterfeiters to reproduce accurately.
Color-Shifting Ink: The denomination numeral in the lower right corner uses special ink that shifts between copper and green when viewed at different angles, creating a dynamic visual security feature.
Watermark: A faint watermark matching the portrait of George Washington is visible when the note is held up to light, running from the right side of the bill.
Federal Reserve Seal: The seal on the left side contains the Federal Reserve District letter and number identifying which regional Federal Reserve Bank issued that particular note.
