Walk into any bank, gas station, or retail checkout line in America and you will likely spot a small ultraviolet lamp tucked near the register, or a clerk holding a twenty up to the light before handing back change. That reflex, now so routine it barely registers, is the direct result of a sustained public education campaign that the Federal Reserve, working alongside the Bureau of Engraving and Printing (BEP) and the United States Secret Service, has been running in various forms since the early 1990s. For currency collectors, this program is far more than a public-safety initiative. Its rollout calendar maps almost perfectly onto the modern era of US banknote design, and understanding it helps you authenticate notes, date security-feature generations, and appreciate exactly why certain series command premiums in the collector market.
Roots of the Program: The Counterfeiting Crisis of the Late 1980s
To understand why the Currency Education Program exists at all, you have to appreciate the threat environment of the late 1980s. The widespread adoption of color photocopiers and desktop publishing software by 1988 and 1989 gave ordinary criminals access to reproduction technology that had previously required sophisticated printing equipment. The Secret Service reported a measurable uptick in low-quality but passable counterfeit notes during this period, particularly in $20 and $50 denominations. Congress responded with the Counterfeit Deterrence Act of 1992, which gave statutory backing to what the Federal Reserve and BEP were already planning: a comprehensive redesign of American currency paired with an unprecedented public education effort.
The first visible fruit of this planning was the Series 1990 family of notes, which introduced the polyester security thread and microprinting around the portrait for the first time. Neither feature had appeared on any previous US currency. The thread on the Series 1990 $100 reads “USA 100” and is visible when held to light. The microprinting on the $100 reads “THE UNITED STATES OF AMERICA” along the left edge of the portrait. These were machine-readable and human-verifiable features, and the Fed immediately faced the challenge of telling 250 million Americans they existed.
Series 1990 notes are the first US Federal Reserve Notes with the polyester security thread. A crisp, uncirculated Series 1990 $100 Federal Reserve Note graded PMG 65 EPQ or better is genuinely collectible and often sells in the $150 to $300 range depending on district and signature combination. Look for the Villalpando-Brady signature pairing, which was used only briefly on early 1990 printings.
The 1996 Redesign and the Birth of Systematic Public Education
The Series 1996 notes represented the most dramatic visual overhaul of US paper money since 1929. The $100 introduced the color-shifting ink (CSI) in the numeral at the lower right, a larger off-center portrait of Franklin, a watermark portrait visible in transmitted light, and a redesigned security thread now reading “USA 100” in addition to being UV-fluorescent in pink. The $50 and lower denominations followed on a staggered schedule through 1997 and 1998.
The Federal Reserve launched a coordinated media campaign in conjunction with the Series 1996 release, targeting both domestic consumers and the enormous overseas market for US dollars. At the time, estimates suggested that roughly 60 percent of all US currency in circulation was held outside the United States, primarily in Russia, Eastern Europe, and Latin America, where dollars were trusted stores of value. The campaign produced multilingual brochures, bank teller training materials, and the earliest iteration of what would become the CEP’s signature “tilt, tilt, and hold to light” three-step authentication check.
When collecting Series 1996 $100 notes, pay close attention to the color-shifting ink. On circulated notes, this ink is frequently worn and loses its shift between copper and green. Always test the shift before purchasing a raw note described as “circulated but attractive.” A note with dead or faded CSI is a red flag for either heavy use or, rarely, a sophisticated fake.
How the CEP Is Structured Today
The modern Currency Education Program, operating under the domain uscurrency.gov since its 2013 relaunch, is a joint effort between the Federal Reserve Board, the BEP, and the Secret Service. It is organized around three audiences: the general public, retail and banking professionals, and international users. Each audience receives tailored materials, but all three tracks emphasize the same core authentication hierarchy.
For the general public, the CEP promotes what it calls the “Feel, Tilt, and Hold” method. Feel refers to the intaglio printing process used by the BEP, which creates a tactile texture on the portrait, numerals, and Treasury seal that is physically impossible to replicate with a standard inkjet or laser printer. Tilt refers to the color-shifting ink present on the $100 (since 1996), $50 (since 1997), and the $100 with the additional color-shifting bell in the inkwell (since the Series 2009A redesign in 2013). Hold refers to the watermark and security thread check performed by holding the note to a light source.
For retail and banking professionals, the program offers free training modules through its website, a dedicated educator toolkit launched in 2016, and physical training aids including side-by-side genuine and counterfeit note comparisons. The CEP also maintains a speaker bureau through the Federal Reserve’s twelve regional banks, which will dispatch currency education specialists to trade associations, retail chains, and banking conferences on request.
The international component of the program, critically important given dollar dollarization in countries like Ecuador, El Salvador, Cambodia, and Zimbabwe, uses translated materials in more than 20 languages. The program partners with the US State Department and international central banks to distribute authentication guides wherever US currency circulates as a primary medium of exchange.
Security Features by Generation: A Collector’s Timeline
For collectors, the security feature generations that the CEP has taught the public to recognize also serve as a precise dating tool for any modern Federal Reserve Note.
Generation 1 (Series 1990-1993): Polyester security thread with microprinting. Thread is not UV-fluorescent on the $100 at this stage; UV fluorescence was not added until the Series 1996 redesign. These notes have the traditional small portrait centered on the face.
Generation 2 (Series 1996-1999): Large off-center portrait, color-shifting ink on $100 and $50, UV-fluorescent security threads with denomination-specific colors ($100 pink, $50 yellow, $20 green, $10 orange, $5 blue), digital watermark portrait, and fine-line printing patterns in the background. This generation is when the CEP’s education effort became truly systematic.
Generation 3 (Series 2004-2006): Introduction of background color into US currency for the first time since Demand Notes and early Legal Tender Notes of the 1860s. The $50 received a red and blue background, the $20 a green and peach background. The $10 added an orange, yellow, and red background. This generation also added the EURion constellation, a pattern of rings embedded in the design that causes modern photocopiers and image editing software to refuse to reproduce the note.
Generation 4 (Series 2009 and 2009A, released 2013): The current $100 design introduced the 3D Security Ribbon, a woven blue ribbon with shifting bells and 100s when tilted, and the Liberty Bell in the copper inkwell that shifts to green ink when tilted. This is the most sophisticated publicly deployed security feature in US currency history, and the CEP devoted an entire separate launch campaign to it, complete with a redesigned website and a national television advertising buy in October 2013.
The Series 2009A $100 note, which carries the Rios-Geithner signature combination and introduced the 3D Security Ribbon, had its printing delayed by significant production problems at the BEP’s Fort Worth, Texas facility. Notes with the “FW” plate position indicator on the back lower right were among the first released. Early delivery of these notes created short-lived premiums for uncirculated examples, and star notes from this printing remain sought after.
Counterfeiting Statistics and What They Tell Collectors
The Secret Service’s annual counterfeiting statistics, published through the CEP’s research portal, offer collectors a useful lens for understanding which denominations have historically attracted the most criminal attention and therefore received priority security upgrades. In fiscal year 2022, the Secret Service reported passing approximately $97.1 million in counterfeit currency, with digital counterfeiting (inkjet and laser printing) accounting for roughly 70 percent of all cases. The $20 note accounted for the single largest share of passed counterfeits, which is consistent with the pattern seen every year since at least 2000.
This concentration on the $20 is precisely why Series 2004 $20 notes received background color, the EURion constellation, and an upgraded security thread before the $10 or $5 denominations received their own overhauls. It also explains why genuine uncirculated Series 2003A $20 notes, the last series before the color redesign, are collected as a transitional type.
The CEP and the Collector Community
Perhaps counterintuitively, the Federal Reserve’s Currency Education Program has been an asset to the collector community as well as the general public. By clearly documenting every security feature added to each series, the CEP has created an inadvertent authentication roadmap. Collectors and third-party grading services like PMG (Paper Money Guaranty) and PCGS Currency use the same feature knowledge that the CEP disseminates to verify that a note is consistent with its stated series and to identify sophisticated fakes.
The CEP’s resources also help collectors understand what makes certain series transitionally significant. The first series to incorporate each new feature is almost always more collectible than later series with the same feature, simply because it represents a historical first in US currency design. The Series 1990 $100 with its inaugural security thread, the Series 1996 $100 with its first color-shifting ink, and the Series 2009A $100 with its 3D Security Ribbon are all examples of notes that carry premiums precisely because they are the originating series for features that the CEP then spent years teaching the public to recognize.

Practical Authentication for Collectors: Applying CEP Methods
The CEP’s three-step method translates directly into useful collecting practice. Before purchasing any modern Federal Reserve Note in raw (ungraded) form, apply the same checks the program teaches the general public, but with a collector’s precision.
First, feel the printing. Genuine intaglio printing has a crisp, slightly raised texture that you can feel with a fingernail dragged across the portrait or Treasury seal. A flat, smooth surface almost always indicates inkjet or toner-based reproduction. This test works even on circulated notes, though heavy wear does reduce tactile relief.
Second, tilt the note and check color-shifting ink. On $100 notes from Series 1996 onward, the numeral in the lower right shifts from copper to green. On Series 2009A $100 notes, the Liberty Bell in the inkwell also shifts. A dead, non-shifting numeral on what is claimed to be a Series 1996 or later $100 is a serious authentication concern.
Third, hold to light and verify both the watermark and the security thread. The watermark on $100 notes from Series 1996 onward is a second portrait of Franklin, visible to the right of the printed portrait. The security thread should be embedded in the paper, not printed on the surface, and should glow pink under UV light. Any note where the thread appears to be a surface stripe rather than an embedded element should be treated with extreme suspicion.
Invest in a good dual-wavelength UV lamp that operates at both 365nm (longwave) and 254nm (shortwave). The CEP recommends 365nm UV for checking security threads, but experienced collectors also use shortwave UV to examine paper fluorescence. Genuine BEP currency paper has very low fluorescence under UV because it contains no optical brighteners, while most copy paper glows bright blue-white. This single test eliminates the vast majority of inkjet-printed counterfeits immediately.
Conclusion: An Education Program That Benefits Everyone in the Hobby
The Federal Reserve’s Currency Education Program began as a crisis response to the democratization of counterfeiting technology in the late 1980s and has evolved into one of the most comprehensive public financial literacy programs ever maintained by a central bank. For the general public, it has helped keep confidence in US currency high even as counterfeiting technology has continued to advance. For currency collectors, it has created a precise, well-documented record of every security innovation incorporated into US banknotes over the past three-plus decades, a record that functions as an authentication guide, a series-dating tool, and a roadmap to the transitional issues that make modern US currency genuinely collectible.
The next time you pick up a $100 note and instinctively tilt it to watch the bell shift from copper to green, you are participating in one of the most successful public education campaigns in American financial history. And if you are a collector, you are also looking at exactly the kind of design inflection point that makes the Series 2009A $100 a note worth seeking out in the finest grades you can find.
