Counterfeit money is a serious problem, and it is important to be able to spot it. Counterfeiters are constantly developing new ways to make their bills look more real, but there are still some things that you can look for to help you determine if a $100 bill is real or fake.

Check the Watermark

One of the easiest ways to tell if a $100 bill is counterfeit is to check for the watermark. The watermark is a faint image of Benjamin Franklin that can be seen when you hold the bill up to a light. It should be located to the right of the portrait.
Check the Security Thread

Another way to tell if a $100 Dollar bill is counterfeit is to check for the security thread. The security thread is a thin, plastic strip that is embedded in the paper of the bill. It should run vertically from the top to the bottom of the bill. When you hold the bill up to a light, you should be able to see the thread and the words “USA 100” printed on it.

Check the Color-Shifting Ink

The number 100 on the front of the bill is printed with color-shifting ink. When you tilt the bill, the number should change color from copper to green.

Check the Paper Quality

Genuine U.S. currency is made from a special type of paper that is difficult to counterfeit. The paper should feel crisp and thick. It should also have a slightly textured feel to it.

Check the Printing

The printing on genuine U.S. currency is very high quality. The lines should be sharp and clear, and there should be no blurry or uneven areas.

Check the Microprinting

There is small, detailed printing on the front and back of the bill. This printing is very difficult to counterfeit. Look for the microprinting on the bell in the inkwell on the front of the bill. It should say “USA 100” in very small letters.

Check the Serial Numbers

The serial numbers on genuine U.S. currency are unique and printed in a specific way. The numbers should be evenly spaced and the font should be consistent. The serial numbers should also be printed on the front and back of the bill in the same location.

Additional Tips

In addition to checking for the features listed above, there are a few other things that you can do to help you determine if a $100 bill is counterfeit.

Be aware of the latest counterfeiting techniques. Counterfeiters are constantly developing new ways to make their bills look more real. If you are not familiar with the latest techniques, you may be more likely to be fooled.
Be suspicious of bills that look too good to be true. If a bill is crisp, new, and has perfect printing, it is more likely to be counterfeit.
Be wary of bills that are received from strangers or in unusual circumstances. If you receive a bill from someone you do not know or in a situation where it is not clear where the bill came from, it is more likely to be counterfeit.
If you are unsure about the authenticity of a bill, do not accept it. It is better to be safe than sorry.


Conclusion

By following these tips, you can help to protect yourself from being the victim of counterfeit money. If you believe that you have received a counterfeit bill, you should report it to the police or to your local bank.
