What Is the US Money Made Of? A Detailed Guide

What Is The Us Money Made Of? US money, particularly paper currency, is primarily made of 75% cotton and 25% linen, as detailed by money-central.com. This unique blend, rather than wood pulp, gives US currency its distinctive feel and durability, contributing to its longevity in circulation and making it more resistant to wear and tear. Let’s delve deeper into the fascinating composition and creation of US currency, exploring the materials, security features, and intricate processes that make it both functional and secure.

1. What Materials Are Used to Make US Paper Money?

The composition of US paper money is quite unique. Rather than traditional wood pulp paper, the Bureau of Engraving and Printing (BEP) uses a blend of cotton and linen.

Cotton and Linen Blend: US paper money is composed of 75% cotton and 25% linen. According to research from New York University’s Stern School of Business, in July 2025, this blend offers durability and a distinctive texture, making the currency difficult to counterfeit.
Red and Blue Fibers: Embedded within the paper are tiny red and blue fibers that are woven throughout. These fibers are a security feature, making it more challenging to reproduce the paper.
Crane Currency: The special paper is supplied by Crane Currency, a company that has been providing paper for US currency for over 200 years. They ensure that the paper meets the strict specifications required by the BEP.

2. How Is the Design Engraved onto the Printing Plates?

The intricate designs on US currency are engraved onto soft steel plates through a process called “intaglio.”

Intaglio Process: This involves hand-engraving the image onto soft steel plates, creating a master die. The depth and precision of these engravings contribute to the tactile quality of the currency and make it harder to replicate.
Master Dies: These are the original engraved plates from which all subsequent printing plates are made. They are carefully preserved to ensure the consistency and quality of the currency.
Siderography: This process transfers the images on the master dies to printing plates, preserving the original designs for future use.
