1. Watermark Test: How Do You Know a 100 Dollar Bill is Real?

One of the most reliable ways to determine if a $100 bill is real is by examining the watermark. Look for the portrait of Benjamin Franklin in the top left corner. When you hold the bill up to the light, you should see a clear, slightly raised image of Franklin. This watermark is a crucial security feature that is difficult to replicate in counterfeit bills.

2. Color Shifting Ink: How Do You Know a 100 Dollar Bill is Real?

Another key feature of the $100 bill is the color-shifting ink. The number “100” on the front and back of the bill changes from copper to green when you tilt it. This is a sophisticated security feature that’s hard to mimic in fake currency. If the color doesn’t shift, you might have a counterfeit bill on your hands.

3. Security Thread: How Do You Know a 100 Dollar Bill is Real?

The $100 bill also features a security thread that runs vertically through the bill. Look for the word “USA” and the number “100” imprinted on the thread. When you hold the bill up to the light, you should see these imprints clearly. Counterfeiters often struggle to reproduce this detail, making it another excellent way to identify a genuine $100 bill.

4. Raised Printing: How Do You Know a 100 Dollar Bill is Real?

The $100 bill is printed with raised ink, making it feel rough to the touch. Feel the edges and the front and back of the bill to ensure there is a noticeable texture. Counterfeit bills often have a smooth surface, so this is a quick and easy way to determine their authenticity.

5. Micro Printing: How Do You Know a 100 Dollar Bill is Real?

Micro printing is another security feature that can help you identify a real $100 bill. Look for small, raised letters and numbers on the bill. When you hold it up to the light, you should be able to see these details clearly. Counterfeiters often have difficulty reproducing this feature, making it an excellent way to spot fake currency.

6. Portrait of Benjamin Franklin: How Do You Know a 100 Dollar Bill is Real?

The portrait of Benjamin Franklin is a crucial part of the $100 bill’s design. Look for the image of Franklin on the front and back of the bill. Counterfeiters often use poor-quality images or misrepresentations of Franklin, so examining the portrait can help you determine if the bill is genuine.

7. Ultraviolet Light: How Do You Know a 100 Dollar Bill is Real?

If you’re still unsure about the authenticity of a $100 bill, you can use ultraviolet (UV) light to examine it. When exposed to UV light, genuine $100 bills will glow a distinct green color. Counterfeit bills often don’t have this reaction, making UV light an effective tool for identifying fake currency.

In conclusion, knowing how to identify a real $100 bill is essential for anyone dealing with large sums of money. By following these seven foolproof tips, you can confidently spot genuine currency and avoid falling victim to counterfeiters.
