How to Spot a Counterfeit $100 Bill

Detecting a counterfeit $100 bill can be challenging, but knowing what to look for can save you from falling victim to fraud. Start by examining several key features of the bill. First, the texture of genuine bills is distinct. They are made from a special blend of cotton and linen that gives them a unique feel. If the bill feels different, it could be counterfeit.

Second, check the security thread. Genuine $100 bills have a security thread woven into the fabric of the bill. It should be visible when you hold the bill up to the light and should appear to be a continuous line. Counterfeit bills might have a similar strip, but it often doesn’t match the security thread in genuine currency.

Third, inspect the color-shifting ink. On a real $100 bill, the lower right corner of the front of the bill features a color-shifting ink that changes from green to black as you tilt the bill. Counterfeit bills may have similar coloring but will not shift in color correctly.

Fourth, observe the fine details and microprinting. Genuine $100 bills have fine lines and tiny text that are sharp and clear. Use a magnifying glass to inspect these details closely. Counterfeit bills often lack the sharpness and clarity of the genuine ones.

Fifth, check the portrait. On a genuine $100 bill, Benjamin Franklin’s portrait should be detailed with fine lines and shading. Counterfeit bills may have a blurred or flat appearance.

Sixth, verify the watermark. Hold the bill up to the light to see a faint image of Benjamin Franklin’s face on the right side of the bill. This watermark should be visible from both sides of the bill.

Seventh, review the blacklight features. Under a blacklight, genuine $100 bills will show a variety of colors, including a security thread that glows pink. Counterfeit bills often fail to replicate these features accurately.

Eighth, use a counterfeit detection pen. These pens contain a special ink that reacts with the paper used in counterfeit bills. If the ink turns dark, the bill is likely fake. However, be aware that some counterfeiters use paper that can fool these pens.

Ninth, examine the bill's print quality. Genuine bills are printed using sophisticated techniques that result in clear, crisp lines and details. Counterfeit bills may show signs of poor print quality, such as smudges or inconsistencies.

Tenth, review the serial numbers. Genuine $100 bills have unique serial numbers that are evenly spaced and printed with high precision. Counterfeit bills may have serial numbers that are uneven or poorly printed.

By paying attention to these features, you can increase your chances of spotting a counterfeit $100 bill before it's too late. The more you familiarize yourself with the look and feel of real currency, the better equipped you'll be to identify fake bills.
