Contrary to popular belief, the material used for U.S. currency is not standard paper made from wood pulp.
Composition of Currency Material
The "paper" used for U.S. dollar bills is actually a unique blend designed for durability and security. According to the provided reference:
- U.S. currency paper is composed of 25% linen and 75% cotton.
- It includes red and blue fibers distributed randomly throughout the material.
This specific composition makes the bills much more durable than typical paper, allowing them to withstand frequent handling and folding without easily tearing.
Why Cotton and Linen?
Using a blend of cotton and linen instead of wood pulp offers several advantages:
- Durability: Cotton and linen fibers are longer and stronger than wood pulp fibers, giving currency bills greater strength and resistance to wear and tear.
- Feel: The texture is distinct from regular paper, which is a security feature as it makes counterfeiting more difficult.
- Lifespan: This material allows bills to last longer in circulation compared to if they were made from wood-based paper.
The addition of scattered red and blue fibers serves as another layer of security, making it harder for counterfeiters to replicate the material precisely.
| Material Component | Percentage | Purpose |
|---|---|---|
| Cotton | 75% | Provides strength and durability |
| Linen | 25% | Adds crispness and further durability |
| Red & Blue Fibers | Random | Security feature to deter counterfeiting |
This unique blend ensures that the material used for money is robust, has a distinctive feel, and incorporates built-in security elements.
