How to Tell If an Old $100 Bill Is Real

Introduction:

Collecting old currency can be a fascinating hobby, but it's important to be able to distinguish between genuine bills and forgeries. One of the most valuable bills in the currency collection world is the $100 bill. This article will provide you with some tips and techniques on how to tell if an old $100 bill is real.

1. Check the Serial Number:

The serial number on a genuine $100 bill is printed in a clear, legible font. If the serial number appears blurry, faded, or has irregular spacing, it may be a forgery. Genuine serial numbers also have a unique pattern, and the letters and numbers are not repeated consecutively.

2. Observe the Color:

The color of a genuine $100 bill is a rich, deep blue. If the bill appears to be a lighter shade of blue or has an uneven color, it may be a counterfeit. Pay attention to the color of the denominational numeral as well. Genuine bills have a distinct color for each denomination, and the $100 bill's numeral should be a vibrant orange.

3. Look for Security Features:

The United States Treasury has implemented various security features to prevent counterfeiting. Here are some key features to look for:

a. Watermark: Hold the bill up to the light and look for a watermark of Benjamin Franklin's portrait. The watermark should be clear and legible.

b. Security Thread: Genuine $100 bills have a security thread embedded in the paper. Look for a faint, colored line that runs vertically through the bill. When you move the bill, the thread should shift from green to copper.

c. Microprinting: Look for small, fine print on the bill. Genuine bills have microprinting on various parts, including the portrait of Franklin, the Federal Reserve seal, and the numeral 100.

4. Feel the Paper:

Genuine $100 bills are made from a special, durable paper that feels thick and smooth. If the bill feels thin or has a rough texture, it may be a forgery. Additionally, genuine bills have a distinctive texture that can be felt when running your fingers over the paper.

5. Check the Ink:

The ink used on genuine $100 bills is of high quality and should be clear and consistent. If the ink appears to be faded, smudged, or has an uneven color, it may be a counterfeit.

6. Compare with Known Authentic Bills:

If you have access to a known authentic $100 bill, compare the bill in question with it. Look for similarities in the design, color, and security features. Genuine bills often have a consistent quality and design throughout the series.

Conclusion:

Identifying genuine $100 bills can be challenging, but by following these tips and techniques, you can increase your chances of determining the authenticity of an old bill. Always exercise caution when purchasing or selling old currency, and consider consulting with a professional appraiser if you're unsure about a bill's authenticity. Happy collecting!
