The Little-Known Security Feature Most People Miss
At PennyVerse.info, we’re always researching ways to help you protect your money. While most people know about the pen test and security strip, there’s a hidden alphabet code in every genuine $100 bill that counterfeiters often get wrong.
Decoding the Federal Reserve Indicator
Where to Look:
- Locate the black Federal Reserve seal (left side of bill)
- Find the tiny letter and number combination near the seal
- Example: “E5” shown in the TikTok video
- Another example: “B2” on other bills
How It Works:
- The letter represents the Federal Reserve Bank that issued the bill
- The number must match the letter’s position in the alphabet
Correct Combinations:
| Letter | Number | Federal Reserve Bank |
|---|---|---|
| A | 1 | Boston |
| B | 2 | New York |
| C | 3 | Philadelphia |
| D | 4 | Cleveland |
| E | 5 | Richmond |
| F | 6 | Atlanta |
| G | 7 | Chicago |
| H | 8 | St. Louis |
| I | 9 | Minneapolis |
| J | 10 | Kansas City |
| K | 11 | Dallas |
| L | 12 | San Francisco |
Real-World Examples From the Video
✅ Genuine Bill Example: “E5”
- E = 5th letter of alphabet
- Issued by Federal Reserve Bank of Richmond
❌ Fake Bill Example: “Z1”
- Z = 26th letter (should be “Z26”)
- Immediate red flag for counterfeit
