7 Tips for Detecting Counterfeit Money

Counterfeit money has been a challenge since currency was first introduced, and as forgery techniques have improved, it has become increasingly difficult to distinguish real bills from fake ones. While many businesses use machines to detect counterfeit currency, it's essential to know how to spot fakes manually, especially when such equipment is not available.

Here are some practical tips to help you recognize counterfeit bills and protect your business:

1. Examine the Serial Number
   Real U.S. banknotes feature serial numbers that are uniformly spaced and printed with the same ink as the Treasury Seal. Counterfeit bills may have serial numbers that differ in both color and spacing. If you have two bills with identical serial numbers, at least one of them must be counterfeit.

2. Look for Color-Shifting Ink
   On denominations of $10, $20, $50, or $100, check the lower right corner for color-shifting ink. The ink used changes color when tilted — for instance, copper turns green on a $100 bill. Older versions of these bills may transition from green to black.

3. Inspect for a Watermark
   A watermark, typically resembling the portrait on the bill, is visible when held to light. It is created with varying paper thickness, making it a significant security feature that counterfeiters usually cannot replicate effectively.

4. Check the Security Thread
   A security thread is woven into the bill during printing and is visible when held up to the light. Authentic notes display a dark line that reflects metallic sheen and glows under UV light in specific colors depending on the denomination.

5. Assess the Paper Quality and Texture
   Real currency is made from a blend of 25% linen and 75% cotton, featuring red and blue security fibers embedded throughout. In contrast, counterfeit bills often have these fibers printed on the surface, making them easier to identify as fakes.

6. Utilize Counterfeit Detector Pens
   Counterfeit detector pens are handy tools for quickly evaluating the authenticity of banknotes. When you draw a line on the bill, a dark line may indicate a possible fake, while an amber line suggests authenticity.

7. Employ Counterfeit Detection Machines
   Given the widespread issue of counterfeit money, utilizing detection machines is highly recommended for businesses. These devices can accurately identify fake notes, minimizing human error and providing quick assessments of banknote authenticity.

The U.S. dollar, along with other currencies like the British pound and the Euro, is commonly counterfeited. With an increase in cash circulation, the prevalence of counterfeit bills also rises.

For effective counterfeit detection, consider using the M2-ULTRA(AL-931) Counter. This machine is designed for quick and reliable counting of mixed denominations and offers counterfeit detection features, ensuring your business's financial safety.
