The Series 1985 $100 Federal Reserve Note, featuring the familiar "small portrait" of Benjamin Franklin, is a piece of US currency history that often sits unnoticed in collections or old wallets. Today, as of December 20, 2025, most circulated notes are worth face value—$100. However, a small percentage of these vintage banknotes possess specific, rare characteristics that can instantly multiply their value, turning a common bill into a collector’s prize worth hundreds, and sometimes thousands, of dollars.

This comprehensive guide will walk you through the seven critical factors that determine if your 1985 $100 bill is a hidden gem. From identifying the crucial 'Star Note' symbol to decoding the signatures of Treasurer Katherine Davalos Ortega and Secretary James A. Baker III, understanding these details is essential for any currency collector, or numismatist, looking to cash in on this classic paper money.

Key Features and Collectibility Factors of the Series 1985 $100 Bill

The Series 1985 $100 bill is a significant note because it was one of the last series printed before the introduction of modern security features like the security thread and color-shifting ink, which began appearing in the 1990s. This makes the 1985 note a classic example of the "small portrait" design, with Benjamin Franklin’s image centered on the face and a detailed engraving of Independence Hall on the reverse.

The note’s value is determined by a combination of its condition and the rarity of its identifiers. Here are the seven critical elements to check on your Series 1985 note:

1. The Crucial Star Note Indicator (Replacement Notes)

The single most important factor for an immediate value increase is the presence of a Star Note. A Star Note (or Replacement Note) is printed by the Bureau of Engraving and Printing (BEP) to replace a bill that was flawed during the printing process.

  • How to Spot It: Look at the serial number. If the last digit of the serial number is replaced by a solid five-pointed star (*), you have a Star Note.
  • Value Impact: While standard circulated 1985 notes are worth $100, a Star Note in Extremely Fine condition can be valued at around $200. An uncirculated Star Note (graded MS-63 or MS-64) can sell for approximately $425 or more, depending on the specific Federal Reserve District (FRD) that issued it.

2. Fancy Serial Numbers: Rarity in Digits

Beyond the Star Note, the sequence of the eight-digit serial number can dramatically increase the bill's value. Collectors pay a premium for "Fancy Serial Numbers" due to their unique patterns.

Look for these highly desirable sequences:

  • Solid Serial Numbers: All eight digits are the same (e.g., 77777777). These are exceedingly rare and highly valuable.
  • Repeater Serial Numbers: The first four digits repeat the second four (e.g., 12341234).
  • Radar Serial Numbers: The number reads the same forwards and backward (e.g., 12344321).
  • Ladder Serial Numbers: The digits ascend or descend sequentially (e.g., 12345678).
  • 7-in-a-Row: Seven of the eight digits are the same (e.g., 57777777).

3. Printing Errors and Misalignment

Notes with verifiable printing errors are some of the most sought-after banknotes. These errors occur when the Bureau of Engraving and Printing (BEP) machinery malfunctions, resulting in a unique, flawed bill that slipped past quality control.

  • Off-Center Errors: The most common error involves the bill's second or third printing stage being misaligned, causing the borders to be unevenly printed. A dramatically misaligned note (Out-of-Registration Error) can be listed for sale at prices starting from $250.
  • Missing Print: Notes where one of the printing stages (such as the green Treasury Seal or the black Federal Reserve Seal) is partially or completely missing.

4. Condition and Grading (The Preservation Factor)

The physical state of the 1985 $100 bill is paramount. Grading is done on a scale from 1 (Poor) to 70 (Gem Uncirculated). The difference in value between a circulated note and a pristine one is vast.

  • Uncirculated (UNC or MS-60 to MS-70): A note with no folds, creases, or signs of handling. These notes command the highest prices. An Uncirculated 1985 standard note can be valued between $120 and $140.
  • Extremely Fine (EF or XF-40 to XF-45): The note may have one or two light folds but remains crisp and clean.
  • Circulated: Any note with multiple folds, tears, stains, or heavy signs of wear is typically worth only its face value of $100.

5. The Signatures: Ortega and Baker III

Every Federal Reserve Note bears the signatures of the U.S. Treasurer and the Secretary of the Treasury. The Series 1985 notes are distinctive because they feature the signatures of Treasurer Katherine Davalos Ortega and Secretary James A. Baker III (known as the Ortega-Baker signatures).

While the signatures themselves do not typically add premium value unless the note is a rare Star Note or Error, they are a key identifier for the series, confirming its authenticity and specific production period (printed November 1985 through June 1989).

6. Federal Reserve District and Letter Code

The Series 1985 notes were issued by one of the twelve Federal Reserve Banks. The issuing bank is identified by a letter and a number in the black seal on the left side of the bill, known as the Federal Reserve District (FRD) indicator. Some districts may have fewer surviving notes, making them rarer and potentially more valuable to a collector seeking a complete set of all 12 districts.

The 12 Federal Reserve Districts are:

  • 1 (A): Boston
  • 2 (B): New York
  • 3 (C): Philadelphia
  • 4 (D): Cleveland
  • 5 (E): Richmond
  • 6 (F): Atlanta
  • 7 (G): Chicago
  • 8 (H): St. Louis
  • 9 (I): Minneapolis
  • 10 (J): Kansas City
  • 11 (K): Dallas
  • 12 (L): San Francisco

7. The Absence of Modern Security Features

The Series 1985 $100 bill is part of the older currency design, which is notable for what it lacks: a security thread and a watermark. These features were introduced in later series to combat counterfeiting. The 1985 note relies on traditional security measures, such as intaglio printing (raised ink), the red and blue fibers embedded in the paper, and microprinting (which was not yet a prominent feature on the 1985 series).

While this absence doesn't directly increase value, it is a defining characteristic that differentiates the "small portrait" 1985 bill from the modern "large portrait" notes, making it a distinct historical collectible for those who appreciate the classic US currency aesthetic.

Final Assessment: Is Your 1985 $100 Bill a Keeper?

To summarize the value of your Series 1985 $100 Federal Reserve Note, follow this checklist:

  1. Face Value: If the note is circulated with multiple folds and no special features, its value is $100.
  2. Collectible Value (Low): If the note is in Uncirculated condition (crisp, no folds) but has no other special features, the value is approximately $120–$140.
  3. Collectible Value (High): If the note is a Star Note or features a verifiable Printing Error (like an off-center misalignment), the value begins at $200 and can easily climb to $425 or higher, especially in pristine, uncirculated condition.
  4. Numismatic Jackpot: If your note combines a rare feature (Star Note or Error) with a highly desirable Fancy Serial Number (like a Solid or Radar number), it should be professionally graded by a service like PCGS or PMG, as its value could be substantial and is determined by auction.

Always handle your 1985 $100 bill with care, especially if it appears to be in high-grade condition. Avoiding folds and creases is the best way to preserve its potential numismatic value for future generations of collectors.
