DOLLAR DEFENSE
Mastering the Art of Currency Authentication
Is Your Money Real?
The U.S. dollar is the pillar of the global economy, but its prestige makes it a prime target. Don’t let a counterfeit bill erode your hard-earned savings. By mastering just a few sensory and visual checks, you can become an expert filter against fraud. Knowledge is your best insurance.

The DNA of a Dollar
Counterfeiters often fail at step one: the paper. Genuine U.S. currency isn’t “paper” at all in the traditional sense.
It is a proprietary blend that gives the bill its unique “body,” crispness, and durability.
While fakes use wood pulp (standard printer paper) treated with starch, real money is a textile blend.
This is why the “Feel Test” is your first line of defense.
- Cotton (75%): Provides the soft, durable base.
- Linen (25%): Adds the crisp, distinctive texture.

Real vs. Fake: The Sensory Gap
Criminals prioritize speed over perfection. By analyzing key sensory attributes, the gap between a genuine bill and a common counterfeit becomes a chasm.
Intaglio Printing (raised ink) creates ridges on the portrait that digital printers cannot mimic.
OVI (Optically Variable Ink) creates a metallic color shift that fakes often render as a flat, muddy color change.
⚠️ The “Starch” Trap
Counterfeiters use starch to stiffen wood paper. A real bill will not react to an iodine pen, but the tactile check is superior.
Quality Score Comparison
Authentic bills score perfect 10s on security features. Fakes struggle specifically with texture and dynamic ink.
The Hidden Spectrum
Embedded within the paper is the Security Thread. It is not printed on top; it is woven in. Under UV light, each denomination glows a specific color to prevent “bill washing” (bleaching a $5 to print a $100 on it).
Evolution of Security
The U.S. Secret Service and BEP continually update designs to stay ahead. The most advanced features are found on the newest bills.
