How To Identify And Verify The New US 100 Bill Using Advanced Security Features
The redesigned US 100 bill, officially circulating as the Series 2009 and 2009A Federal Reserve note featuring Benjamin Franklin, incorporates sophisticated anti-counterfeiting security enhancements including a 3D security ribbon and a color-shifting bell. Authenticating these high-denomination banknotes requires a systematic visual and tactile inspection of microprinting, security threads, and distinct intaglio printing characteristics.
Pre-Authentication Requirements and Equipment Preparation
Verifying a new US 100 bill accurately requires understanding the exact physiological and structural standards established by the Bureau of Engraving and Printing (BEP). Unlike older currency generations, the modern hundred-dollar bill relies on dynamic optical technologies that cannot be easily replicated by standard inkjet or laser printing devices.
- Essential tools and materials for manual verification include a UV light source (365nm wavelength), a standard 10x jeweler's loupe for microprint inspection, and clean-room handling gloves to preserve banknote integrity if forensic analysis is needed.
- Operators must possess foundational knowledge of genuine paper composition, which consists of 75 percent cotton and 25 percent linen, distinct from wood-pulp commercial paper, along with familiarity with tactile raised printing signatures.
- Verification timing takes approximately 15 to 30 seconds per note under standard ambient lighting, requiring zero capital expenditure beyond basic optical magnification and ultraviolet detection gear.
Step-by-Step Authentication Workflow for the New 100 Dollar Bill
Step 1: Inspect the 3D Security Ribbon
Locate the blue 3D security ribbon woven vertically into the paper, rather than printed on the surface. Tilt the banknote back and forth while observing the ribbon to ensure that the bells and the number 100 shift and move from side to side as the angle changes. If the images shift up and down instead of side to side, or if the ribbon appears as a flat printed stripe, the banknote is a counterfeit.
Warning: Counterfeiters frequently use foil stamping or flat metallic strips to mimic the security ribbon, but these replicas completely lack the microscopic lenticular lens technology required to produce dynamic motion.
Step 2: Examine the Color-Shifting Bell in the Inkwell
Look at the copper-colored inkwell on the front right of the bill, which contains a distinct image of a Liberty Bell. Tilt the note to watch the bell transition from copper to green, creating an effect where the bell appears to magically appear and disappear within the confines of the inkwell. Verify that the color shift is smooth and clean, without any bleeding or muddy color transitions.
Step 3: Verify Tactile Feedback and Portrait Intaglio Print
Run your thumb across Benjamin Franklin’s shoulder on the left side of the note to feel the distinctive raised intaglio printing. Genuine US currency features a rough, textured surface generated by high-pressure printing presses forcing paper into engraved plates. A smooth, flat surface indicates a counterfeit produced via offset lithography or digital copying.
Step 4: Transilluminate the Watermark and Security Thread
Hold the 100 dollar bill up to a bright light source to check for the portrait watermark and the embedded security thread. Look for a faint image of Benjamin Franklin visible from both sides of the paper in the blank space to the right of the portrait oval. Simultaneously, locate the embedded security thread running vertically to the left of the portrait, which glows pink under ultraviolet light and spells out USA 100.
Step 5: Check Microprinting with Magnification
Deploy a 10x loupe to scan specific high-density zones on the banknote, including the golden 100 in the lower right corner, the words UNITED STATES OF AMERICA along the golden quill, and around the watermarked portrait frame. Genuine microprinting features crisp, legible text that remains sharp under magnification, whereas counterfeit notes display blurred, coalesced ink dots.

Troubleshooting Common Verification Errors and Field Mistakes
- Root Cause: Misinterpreting surface-level moisture or natural wear and tear as a structural flaw in the paper.
- Actionable Fix: Compare the suspect note side-by-side with a verified genuine note of the same series to isolate true printing anomalies from environmental degradation.
- Root Cause: Failing to account for counterfeit notes bleached from lower-denomination bills (such as authentic $5 bills) and reprinted with $100 designs.
- Actionable Fix: Always check the portrait watermark and the embedded security thread text to confirm that the hidden security elements match a $100 denomination rather than a lower-value note.
- Root Cause: Relying exclusively on handheld UV light pens without verifying optical security threads.
- Actionable Fix: Combine UV testing with tactile assessment and 3D ribbon observation to establish a multi-point verification protocol that defeats sophisticated chemical wash techniques.
Frequently Asked Questions
How can I instantly tell if a new $100 bill is real?
The fastest way to verify a new $100 bill is to tilt it to check the blue 3D security ribbon and the color-shifting bell in the inkwell. On a genuine note, the bells and numbers on the ribbon move side to side, and the bell changes from copper to green.
Are older series $100 bills still legal tender?
Yes, all United States Federal Reserve notes issued since 1914 remain legal tender at full face value regardless of their series year. Businesses and financial institutions are not required to accept redesigned notes over older series, though merchants retain the right to establish individual cash-handling policies.
What should I do if I receive a suspected counterfeit $100 bill?
Do not return the counterfeit banknote to the passer, and avoid putting yourself in physical danger. Note the description of the person who provided the bill, preserve the note in an envelope to protect fingerprints, and contact local law enforcement or the United States Secret Service immediately.
Why do some $100 bills not have the blue security ribbon?
Bills lacking the blue security ribbon belong to older design series, specifically Series 1990 through 2006, which feature different security threads and watermarks. These older bills are still authentic and legal tender, provided they pass standard tactile and visual security checks.
Does the UV light test work on all genuine $100 bills?
The ultraviolet light test reveals a pink glowing thread embedded in the paper for modern series bills. However, older series bills feature different UV thread colors or lack threads entirely, meaning UV testing must be paired with physical paper and intaglio inspections.
