Color-Shifting Ink

The numeral “20” in the lower right corner of a legitimate $20 bill features color-shifting ink, transitioning from copper to green when tilted.

This feature is hard to replicate, skilled counterfeiters can imitate it, necessitating further authentication steps.


Intricate micro printing, such as “USA20” adjacent to the security thread and specific phrases beneath the Treasurer’s signature, is challenging to reproduce without high-quality printers.

Unfortunately, many counterfeiters have access to technology that enables them to mimic these effects, making it crucial to authenticate using specialized tools.


Authentic $20 bills reveal a watermark of Andrew Jackson when held up to light, visible from both sides. Some counterfeiters attempt to replicate this using digital printers or washing $5 bills to print $20 denominations, though discerning the subtle differences in watermarks is essential.

Security Thread

Post-2003 $20 bills contain a security thread with “USA TWENTY” and an American flag visible when held to light, glowing green under ultraviolet light.

Despite efforts to replicate this feature, counterfeiters, especially in Peru, have devised techniques to duplicate security strips manually.

Color and Paper

New $20 bills incorporate green, peach, and blue inks with embedded blue and red microfibers in the paper. Counterfeiters may resort to techniques like money washing or using recycled paper coupled with advanced printing technology to mimic these characteristics.

Detecting Counterfeit Money

Several methods exist to authenticate a $20 bill, including counterfeit detector pens and more advanced scanning devices.

These tools aid in verification, but they are not infallible, emphasizing the importance of visual inspection, commonly referred to as the eye test.

The Eye Test

By verifying specific security features such as the watermark, color-changing ink, security thread, and microprinting, individuals can conduct a basic yet effective authenticity check.

Employing a magnifying glass for microprinting inspection ensures a thorough examination.

What does a fake 20 look like?

Fake $20 bills might lack proper microprinting. Genuine bills feature microprinted text like “USA20” along the border of the “TWENTY USA” ribbon and “THE UNITED STATES OF AMERICA 20 USA 20” below the Treasurer’s signature. Lack of or poorly replicated microprinting can indicate a fake.

How can I check the serial number on my $20 bill?

Genuine $20 bills have unique eight-digit serial numbers, accompanied by identifying letters and numbers denoting the series year and printing location. They are printed twice on the front of the bill.

What does a blue star on a 20 dollar bill mean?

A blue star signifies a replacement note, used when a printing error renders a set of bills unusable during the normal printing process.

Why do some $20 dollar bills look different?

Changes in the design of $20 bills incorporate new security features, such as microprinting and security threads, aimed at enhancing security and deterring counterfeiting. These changes reflect advancements in currency security.

Do all $20 dollar bills have the same serial number?

No, each bill of the same denomination has a unique serial number. The format of serial numbers has evolved over time, with older bills having a different arrangement compared to newer ones.

What is a mismatched serial number on a 20 dollar bill?

A mismatched serial number error refers to inconsistencies between the serial numbers on a bill. Errors like these are a notable aspect of banknote errors, studied by numismatists and collectors.


Ensuring the authenticity of a $20 bill is crucial in preventing legal ramifications and protecting against economic damage.

Combining counterfeit detection tools with visual inspection methods empowers individuals and businesses to identify genuine currency and mitigate the risks associated with counterfeit money.

Investing in a reliable counterfeit money detector can significantly aid in safeguarding against financial losses caused by fake bills.

Spotting a fake $20 bill might seem daunting, but armed with knowledge about the bill’s security features, you’re better equipped to verify its authenticity.
