Who Is On The Hundred Bill And How To Identify Authentic Currency

Benjamin Franklin is featured on the United States one-hundred-dollar bill, serving as both a tribute to a Founding Father and a canvas for advanced anti-counterfeiting security features. Mastering the physical traits, portrait details, and embedded authentication elements of the $100 bill ensures accurate identification in both everyday commerce and financial auditing.

Pre-Operation & Financial Verification Checklist

Before attempting to authenticate, sort, or evaluate high-denomination United States currency, establishing a rigorous handling framework is vital. The Federal Reserve notes that the $100 bill is the most widely circulated and globally targeted denomination for counterfeiting, requiring strict adherence to verification protocols.

• Essential gear/tools/materials: UV light detector (365nm wavelength), magnifying loupe (10x minimum), high-grade cotton-linen currency paper reference, and an authenticated comparison bill.
• Mandatory prerequisite knowledge/standards: Familiarity with Series 2009, 2009A, and 2013 design standards, Bureau of Engraving and Printing (BEP) intaglio printing textures, and color-shifting ink mechanics.
• Estimated budget/duration benchmarks: Visual and tactile inspection takes 5 to 10 seconds per bill; automated UV or magnetic sensor scanning completes in under 1 second with zero financial overhead for basic visual checks.

Step-by-Step Currency Authentication and Portrait Verification Workflow

Step 1: Inspect the Portrait of Benjamin Franklin

Examine the primary engraving on the obverse (front) side of the bill to confirm it depicts Benjamin Franklin. The portrait must be sharp, highly detailed, and distinctly raised from the paper surface due to the intaglio printing process.

1. Run your fingertip across Franklin's shoulder; authentic intaglio printing produces a palpable, rough texture that flat inkjet or laser printers cannot replicate.
2. Check the background behind Franklin for crisp, unbroken fine-line styling that merges seamlessly without blurring or bleeding into the portrait borders.
3. Verify the microprinting around the portrait area, specifically reading "UNITED STATES OF AMERICA" along the rim of the portrait oval and "THE UNITED STATES OF AMERICA" within the numeral 100 in the lower left corner.

Pro-Tip: Genuine portraits appear lifelike and stand out sharply from the background, whereas counterfeit portraits often appear dull, flat, or excessively dark due to poor digital scanning reproduction.

Step 2: Locate and Test the 3D Security Ribbon

Locate the blue ribbon woven into the paper—not printed on it—running vertically on the right side of the portrait. This complex optic feature shifts dynamically as you tilt the bill.

1. Tilt the currency back and forth while observing the blue ribbon.
2. Confirm that the images on the ribbon change from bells to the number 100 as you move the note.
3. Ensure that when you tilt the bill up and down, the bells and 100s move side-to-side, or if you tilt it side-to-side, they move up-and-down, demonstrating micro-optic lens technology.

Warning: If the blue ribbon appears as a flat printed sticker or lacks motion when tilted, the note is an absolute counterfeit.

Step 3: Analyze the Color-Shifting Copper Inkwell and Bell

Examine the copper-colored inkwell located to the right of the portrait, which contains a subtle security image.

1. Inspect the inkwell design, which houses a color-shifting image of a Liberty Bell.
2. Tilt the bill to observe the color of the bell inside the inkwell shift clearly from copper to green.
3. Verify that the large numerical "100" in the lower right-hand corner of the front also exhibits this exact copper-to-green color-shifting characteristic.

Step 4: Verify the Watermark and Security Thread

Hold the $100 bill up to a natural or artificial light source to inspect internal paper features.

1. Look at the blank space to the right of Benjamin Franklin's portrait to find a faint, high-definition watermark depicting a duplicate portrait of Franklin.
2. Inspect the embedded security thread running vertically up the left side of the portrait.
3. Check that the thread glows pinkish-red when exposed to ultraviolet light (365nm) and contains the microprinted text "USA 100" alternating with a small flag.

Common Counterfeit Failures and Field Fixes

• Smooth, Flat Paper Texture
  
  
  • Root Cause: Counterfeiters often use standard wood-pulp copy paper or treated commercial bond paper instead of the official 75/25 cotton-linen blend.
  • Actionable Fix: Perform a tactile check for the distinct crispness and raised intaglio ridges. Reject any note that feels overly smooth, waxy, or limp.
• In static or Dead Security Ribbon
  
  
  • Root Cause: Counterfeiters attempt to mimic the 3D security ribbon using metallic foil strips or simple printed gloss ink lines.
  • Actionable Fix: Tilt the note through a 45-degree arc. If the bells and 100s do not float and switch dynamically, the bill is fraudulent.
• Failed Ultraviolet Thread Response
  
  
  • Root Cause: The embedded security thread is missing entirely, or fake threads fail to fluoresce properly under UV inspection.
  • Actionable Fix: Pass a 365nm UV light over the note to verify the vivid pinkish-red glow of the thread embedded within the paper substrate.
• Blurred or Muddy Microprinting
  
  
  • Root Cause: Standard consumer inkjet or low-end offset printers lack the high-resolution capacity to reproduce micro-text clearly.
  • Actionable Fix: Use a 10x magnifying loupe to inspect the text inside the numeral 100 and along the collar; blurred or solid black lines indicate a counterfeit.

Frequently Asked Questions

Why is Benjamin Franklin on the hundred-dollar bill if he was never president?

Benjamin Franklin is featured on the $100 bill because of his monumental status as a Founding Father, scientist, inventor, diplomat, and signer of the Declaration of Independence. United States currency regulations do not restrict portraits exclusively to past presidents, allowing other historic figures of immense national significance to be honored.

What series of the hundred-dollar bill introduced the modern security features?

The redesigned $100 bill featuring the 3D security ribbon and color-shifting bell was introduced with the Series 2009, which officially entered circulation in February 2011. This redesign aimed to stay ahead of advanced graphic scanning and digital printing technologies used by modern counterfeiters.

How can I quickly check a $100 bill without using electronic equipment?

You can quickly authenticate a $100 bill without tools by performing three rapid physical checks: feel the raised intaglio printing on Franklin's shoulder, tilt the bill to watch the copper inkwell shift to green, and check that the blue 3D security ribbon shows moving bells and 100s.

Are older designs of the hundred-dollar bill still considered legal tender?

Yes, all designs of United States Federal Reserve notes issued from 1914 to the present remain legal tender at their full face value, regardless of their age. The United States government does not demonetize its currency, though older notes lack modern security features and require closer visual scrutiny.

What should I do if someone hands me a suspected counterfeit $100 bill?

Do not return the suspected counterfeit bill to the passer, and do not put yourself in physical danger. Safely note the person's description, preserve the bill by handling it as little as possible to save fingerprints, and immediately report the incident to local law enforcement or the United States Secret Service.
