How to Spot a Fake Old $100 Bill: A Comprehensive Guide

Identifying a fake $100 bill can be crucial to avoid falling victim to counterfeit currency. This guide provides a step-by-step approach to help you determine the authenticity of an old $100 bill. By carefully examining specific features, you can significantly reduce the risk of dealing with a counterfeit note.

Common Features of a Genuine $100 Bill

Here are key characteristics of a genuine $100 bill that you should look for:

1. Paper Quality

Texture: Real bills are made from a unique blend of cotton and linen, resulting in a distinct feel. Fake bills may feel overly smooth or thick. The paper should be crisp and durable.

2. Watermark

Visible Image: Hold the bill up to the light to reveal a faint image of Benjamin Franklin. This watermark should be clearly visible from both sides of the bill. Ensure the image is consistent and not altered or faded.

3. Security Thread

Embedded Security Feature: Real $100 bills contain a security thread embedded in the paper. When held up to the light, the security thread should be visible and should read "USA 100" and "ONE HUNDRED".

4. Color-Shifting Ink

Copper to Green Change: Examine the lower right corner of the bill. When tilted, the ink should change from copper to green. This is a crucial authentication feature.

5. Microprinting

Fine Text Verification: Pay close attention to areas such as the border and the security thread. Genuine bills feature tiny text that is extremely difficult to replicate without specialized equipment.

6. Fluorescence Under UV Light

Color Changes: To authenticate, use a UV light to observe specific features. For instance, the security thread should glow a specific color, such as pink, under UV light.

7. Serial Numbers

Clear and Consistent: The serial numbers on a genuine bill should be clear, evenly spaced, and match the series year of the bill. False bills may have poor or misaligned serial numbers.

8. Overall Print Quality

Careful Examination Required: Genuine bills have crisp, detailed images and text. Any hints of blurriness, smudging, or poor detail could indicate a fake.

9. Dimensions and Size

Exact Measurements: Measure the bill to ensure it is exactly 2.61 inches by 6.14 inches. Compare it with a known genuine bill.

10. Consult Expert Resources

Verification by Professionals: If you are unsure, bring the bill to a bank or currency exchange for professional verification. They have the tools and knowledge to confirm the authenticity of the bill.

Summary: By carefully examining these features, you can significantly improve your ability to identify a fake $100 bill. Should you remain uncertain, seeking professional help is the safest option to ensure you are not dealing with counterfeit currency.
