Inside the Factory: How US Money is Made

Have you ever wondered how the money in your wallet is made? This video takes us inside a high-security facility where millions of dollars are printed every hour. We learn that making a $100 bill is a very complex and precise manufacturing process. It isn’t just about printing ink on paper; it involves advanced technology and materials that are almost impossible to counterfeit.
The Secret Recipe: Not Just Paper
The first surprise is that US money isn’t actually made of paper. It is a textile made of 75% cotton and 25% linen. This material, called the substrate, is stronger than regular paper and has a unique texture. Only one company in Massachusetts has the authorization to make it. Inside this material, tiny red and blue synthetic fibers are scattered to help people identify real bills.
Advanced Security: More Than Meets the Eye
Security features are embedded into the material even before the printing starts. For example, a thin plastic thread is hidden inside the paper. If you put it under ultraviolet light, it glows in different colors depending on the denomination. The $100 bill also has a special blue ribbon with millions of micro lenses. When you tilt the bill, you can see images of bells moving, which is a feature that no home printer can replicate.
The Art of Printing: From Steel to Ink
The printing process uses intricate designs that are hand-carved into steel plates by master artists. This is called intaglio printing. Because the ink is pressed into the paper with great force, you can actually feel the raised texture on the bill. The ink also contains magnetic particles, which allows machines to perform authentication instantly.
Making Change: How Coins Are Stamped
Coins are made differently. They are stamped from large metal coils using huge machines. These metal pieces, called blanks, are heated and washed before being struck with a design. Interestingly, some coins like quarters are very profitable for the government to make, while others, like pennies, actually cost more to produce than they are worth. In fact, the US stopped making pennies for people to circulate in 2025.
In conclusion, every bill and coin is a masterpiece of engineering. Whether it is the engraving on a bill or the recycled metal in a coin, the goal is to create a trusted currency that lasts for many years.
