Who Is On The 100 Dollar Bill: History, Security Features, And Portrait Design

Benjamin Franklin is featured on the United States one-hundred-dollar bill, making him the only non-president depicted on a currently circulating high-value Federal Reserve Note. This comprehensive guide explores the historical significance, advanced security features, redesign history, and technical specifications of the iconic $100 currency denomination.

Historical Context and Portrait Selection Standards

• Understanding the strict United States Department of the Treasury regulations regarding currency portraiture and the unique status of Benjamin Franklin among American statesmen.
• Bulleted checklist categorizing historical prerequisites, portrait criteria, and production benchmarks:
  
  
  • Essential design subjects: Deceased statesmen or Founding Fathers whose likenesses are legally protected and historically verified by the Bureau of Engraving and Printing (BEP).
  • Mandatory engraving standards: Intaglio printing matrices, hand-sculpted steel die execution, and high-contrast tonal mapping suitable for microscopic verification.
  • Estimated production economics: Average paper currency lifespan ranging from 15 to 22.5 years for the $100 denomination, backed by automated optical sorting and destruction infrastructure.

Step-by-Step Anatomy and Verification of the $100 Bill

Step 1: Examine the Portrait and Watermark Intaglio

• Inspect the primary engraving of Benjamin Franklin on the obverse side of the bill using tactile feedback and magnification. The ink should feel distinctly raised due to the intaglio printing process, which applies heavy pressure to press ink into the specialized cotton-linen paper blend.
• Look closely at the blank space to the right of the portrait when held to a light source to reveal a faint, highly detailed watermark of Benjamin Franklin visible from both sides of the note.

Pro-Tip: Always tilt the bill to examine the color-shifting ink on the numeral 100 in the lower right-hand corner, which shifts from copper to green depending on the viewing angle.

Step 2: Verify Advanced Security Thread and Microprinting

• Locate the embedded polymer security thread running vertically to the left of the portrait, which glows pink under ultraviolet (UV) light and contains the microprinted text "USA 100" alongside alternating flag motifs.
• Scan the collar of Benjamin Franklin's coat, the blank space around the watermark area, and the golden 100 numerals for ultra-small alphanumeric characters that require a magnifying glass to read accurately without distortion.

Warning: Counterfeit notes frequently replicate visual color gradients but fail to reproduce sharp, legible microprinting and correct tactile paper fiber composition.

Step 3: Analyze the 3D Security Ribbon and Bell in the Inkwell

• Focus on the blue 3D security ribbon woven into the paper on the front of the note, tilting the bill back and forth to watch the bells and 100 figures shift and transform into one another as you change the viewing angle.
• Check the copper-colored inkwell on the right side of the portrait to observe the color-shifting bell inside, which transitions from copper to green and creates a dynamic visual anchor for modern series notes.

Common Counterfeit Indicators and Authentication Failures

• Root Cause: Use of standard consumer inkjet or laser printing technology on ordinary wood-pulp paper stock.
  
  
  • Actionable Fix: Perform a tactile check for the heavy, textured feel of genuine 75% cotton and 25% linen paper combined with raised intaglio printing, and test for the absence of red and blue security fibers embedded within the substrate.
• Root Cause: Failure to replicate the dynamic optics of the woven 3D security ribbon.
  
  
  • Actionable Fix: Tilt the note 45 degrees vertically; authentic ribbons utilize micro-optics with hundreds of thousands of microlenses that move in the opposite direction of the tilt, whereas counterfeiters typically print a flat, static metallic foil sticker.
• Root Cause: Absence of genuine ultraviolet response markers under commercial blacklight testing equipment.
  
  
  • Actionable Fix: Expose the note to 365nm UV light to verify the glowing pink security thread running vertically through the left-center of the paper stock, distinguishing it from unauthenticated chemical washes.

Frequently Asked Questions

Why is Benjamin Franklin on the 100 dollar bill if he was never president?

Benjamin Franklin is honored on the $100 bill due to his foundational role as a Founding Father, diplomat, printer, scientist, and signer of both the Declaration of Independence and the United States Constitution. United States currency regulations do not restrict portraiture exclusively to former presidents, allowing exceptional statesmen and historical figures to be featured.

What building is featured on the back of the 100 dollar bill?

The reverse side of the $100 bill features an engraving of Independence Hall, located in Philadelphia, Pennsylvania. The clock tower on the building is historically set to approximately 4:10, though exact hands vary slightly across historical series editions.

When was the current design of the 100 dollar bill introduced?

The current redesigned $100 bill featuring the blue 3D security ribbon and color-shifting bell in the inkwell was officially issued by the Federal Reserve on October 8, 2013. This redesign incorporated advanced anti-counterfeiting technology while honoring the classic portraiture of Benjamin Franklin.

Are older versions of the 100 dollar bill still legal tender?

All redesigns of United States Federal Reserve Notes issued from 1914 to the present remain legal tender at their full face value, regardless of their age or missing modern security features. The federal government does not recall or invalidate older currency designs when new series are introduced.
