Walk into any major currency show and you will find stacks of Series 1928 Federal Reserve Notes priced anywhere from a few dollars to several thousand. The casual observer sees a uniform green seal, a familiar portrait, and a denomination. The seasoned collector sees something far more nuanced: a specific signature combination that places that note in a precise window of American history, sometimes a window of fewer than eighteen months. Series 1928 Federal Reserve Notes were produced with four distinct Register of the Treasury and Secretary of the Treasury signature pairings, running from Tate-Mellon through Woods-Mills, and each combination carries its own print run history, distribution quirks, and collector market behavior.
The Transition to Small-Size Currency and Why 1928 Matters
The Series 1928 Federal Reserve Notes represent a watershed moment in American monetary history. The Currency Act of 1929 authorized the reduction of paper currency to approximately 75 percent of the size of large-size notes, and although the legislation passed in 1929, the Bureau of Engraving and Printing began preparing and delivering the new small-size notes in 1928. The first deliveries to Federal Reserve Banks occurred in July 1929, meaning that while the notes carry a 1928 series date, most did not actually circulate until 1929 or later.
This context is critical for collectors because it means the Series 1928 base notes, regardless of signature combination, represent the very genesis of the modern American bill. Every small-size Federal Reserve Note in your wallet descends directly from this series. Collectors prize these notes not only for their historical significance but also because the variety structure, twelve Federal Reserve districts multiplied by multiple denominations and multiple signature pairs, creates an enormous number of legitimate collecting specialties within a single series designation.
The Four Signature Combinations Explained
Tate-Mellon: The Rarest of the Base 1928 Pairings
Walter O. Tate served as Register of the Treasury from April 30, 1928, through January 17, 1929. Andrew W. Mellon served as Secretary of the Treasury from March 4, 1921, through February 12, 1932, making him the anchor signature across multiple series. The Tate-Mellon combination is the rarest of the three signature pairings found on the base Series 1928 notes because Tate’s tenure was exceptionally brief: fewer than nine months. The Bureau of Engraving and Printing’s plate preparation and delivery schedules meant that only the earliest print runs of the initial FRN denominations, primarily $5, $10, $20, $50, and $100 notes, received the Tate-Mellon pairing.
In terms of Friedberg catalog numbers, Tate-Mellon notes on the $20 denomination run from Fr. 2050 through Fr. 2061, covering all twelve Federal Reserve districts. Population reports from major grading services consistently show Tate-Mellon survivors in far smaller numbers than their Woods-Mellon counterparts. A $20 Tate-Mellon note from a district like Minneapolis or Dallas in Very Fine condition can command $150 to $300 or more from a specialist, while a Boston or New York example might trade closer to $75 to $125 in the same grade, reflecting differing regional distribution volumes.
When examining a Series 1928 note for signature variety, look carefully at the printed signatures below the portrait. On Tate-Mellon notes, both signatures tend to be crisply engraved with particularly fine line detail because these notes came from early plate impressions before steel dies experienced significant wear. High-grade survivors often show exceptional plate quality precisely because of this.
Woods-Mellon: The Workhorse Combination
James C. Woods replaced Tate as Register of the Treasury on January 22, 1929, and served until May 31, 1933. Because Mellon remained in place until early 1932, the Woods-Mellon pairing covers the longest stretch of the Series 1928 production window. This combination appears on all twelve denominations issued in the series, from $5 through $10,000, and across all twelve Federal Reserve districts where applicable for each denomination.
Woods-Mellon notes are by far the most commonly encountered Series 1928 base signature variety, which is precisely why condition and district become the dominant value drivers for this pairing. A Woods-Mellon $10 from New York in circulated grades is genuinely common and trades at modest premiums over face value. However, shift your attention to a Woods-Mellon $500 or $1,000 note, and scarcity becomes overwhelming regardless of signature pair. The $500 FRN (Fr. 2200-2211 range) in Woods-Mellon represents one of the genuinely difficult notes to locate in any grade, with auction appearances measured in single digits annually for some districts.
For the working collector focused on lower denominations, the real sport in Woods-Mellon notes lies in completing a twelve-district set for a single denomination. The $20 denomination is a popular choice because it offers enough survivors to make a complete set achievable, yet enough district-level scarcity (particularly Richmond, Minneapolis, and Kansas City in higher grades) to make the hunt genuinely satisfying.
The twelve Federal Reserve district letters run from A (Boston) through L (San Francisco). When assembling a district set of Series 1928 Woods-Mellon notes, prioritize purchasing the scarcer interior districts, such as Minneapolis (I), Kansas City (J), and Dallas (K), first. These are consistently harder to find in grades above Very Fine and tend to appreciate faster during strong collector markets.
Woods-Mills: The Transition Signature
Ogden L. Mills succeeded Andrew Mellon as Secretary of the Treasury on February 13, 1932, serving until March 4, 1933. Because James C. Woods was already in place as Register, this created the third signature pairing found on base Series 1928 notes: Woods-Mills. This combination covers only about thirteen months of production, from mid-February 1932 through the end of the Series 1928 base print run, making it intermediate in rarity between the brief Tate-Mellon pairing and the extensive Woods-Mellon run.
Woods-Mills notes occupy an interesting market position. They are scarcer than Woods-Mellon examples but not nearly as dramatically rare as Tate-Mellon notes, which creates a pricing dynamic that experienced collectors can sometimes exploit. Dealers who do not specialize in small-size notes sometimes price Woods-Mills examples the same as Woods-Mellon, missing the meaningful premium that many district-denomination combinations deserve. A $10 Woods-Mills note from Atlanta (Fr. 2005 series) or Dallas in Fine to Very Fine condition is genuinely tougher than a casual glance at a price guide might suggest.
It is worth noting that the Woods-Mills signature combination also appears on Series 1928A, 1928B, and 1928C Federal Reserve Notes for certain denominations, as the series suffix designations changed with significant design or policy shifts rather than strictly following signature changes. This overlap is a frequent source of confusion for newer collectors and underscores the importance of cross-referencing Friedberg numbers with the specific note in hand.
A Note on Series 1928A and the Continuation of Signatures
Although this article focuses on the base Series 1928 signature varieties, it would be incomplete without acknowledging that the signature story does not end cleanly with the series designation. The Series 1928A Federal Reserve Notes, which introduced the redeemable in gold clause change, carried over the Woods-Mellon pairing for initial production and then transitioned to Woods-Mills. Series 1928B, the first to drop the gold redemption language following the 1933 gold recall, subsequently introduced the Woods-Woodin pairing (William H. Woodin having replaced Mills) and later the Julian-Woodin and Julian-Morgenthau combinations. Each of these represents its own collecting specialty, but understanding the base 1928 progression is the essential foundation.
When purchasing Series 1928 notes from online auction platforms, always request or examine high-resolution scans of both the face and back of the note. The signature area on lower-grade circulated examples can show wear that makes it genuinely difficult to distinguish between Tate, Woods, Mellon, and Mills signatures without careful magnification. Misattributed listings offering a Tate-Mellon note priced as a common Woods-Mellon example do occasionally appear and represent real opportunities for the attentive buyer.
Grading Considerations Specific to Series 1928 Notes
Series 1928 Federal Reserve Notes are now approaching a century old, and the population of high-grade survivors has been well-documented by PCGS Currency and PMG over the past two decades. For the base 1928 signature varieties, a few grading realities are worth keeping in mind.
First, paper quality varies noticeably across production periods. Early Tate-Mellon examples often exhibit a particularly bright, crisp paper stock that holds detail well, making gem survivors more visually striking than some later printings. Woods-Mellon notes from mid-1930 onward can occasionally show a slightly softer paper surface, though this is a generalization and individual note quality varies considerably.
Second, centering is a perennial issue with Series 1928 notes. The transition to small-size production involved learning curves for the Bureau of Engraving and Printing, and off-center examples are not uncommon. For strict graders, a note with otherwise MS-63 paper quality can be knocked down to MS-62 or even MS-61 if margins are notably uneven. Conversely, a well-centered example with good embossing and bright paper can command a meaningful premium even within a given numeric grade.
Third, star notes (replacement notes, indicated by a star symbol replacing the last letter of the serial number) command significant premiums across all Series 1928 signature varieties and denominations. Star note production for the 1928 series was modest relative to later small-size issues, and the combination of a star serial number with a scarce signature pairing and a lower-population district can create genuinely rare notes that trade at multiples of the standard catalog values.
| Signature Pair | Denomination / Example District | Approx. Survivors (All Grades) | Rarity |
|---|---|---|---|
| Tate-Mellon | $5, All Districts | Est. 1,500-3,000 total | Rare |
| Tate-Mellon | $20, Minneapolis (I) | Fewer than 100 known | Key Date |
| Tate-Mellon | $100, All Districts | Est. 500-1,200 total | Rare |
| Woods-Mellon | $10, New York (B) | Est. 20,000+ survivors | Common |
| Woods-Mellon | $20, Dallas (K) | Est. 800-1,500 survivors | Scarce |
| Woods-Mellon | $500, All Districts | Fewer than 300 total known | Key Date |
| Woods-Mellon | $1,000, All Districts | Fewer than 200 total known | Key Date |
| Woods-Mills | $10, Atlanta (F) | Est. 2,000-4,000 survivors | Scarce |
| Woods-Mills | $20, Kansas City (J) | Est. 400-800 survivors | Rare |
| Woods-Mills | $50, All Districts | Est. 1,000-2,500 total | Scarce |
Building a Meaningful Collection Around These Varieties
There are several productive collecting frameworks for Series 1928 signature varieties. The most ambitious is a complete type set: one example of each signature combination across all denominations for which that combination was produced. This is a genuinely long-term project requiring patience, a specialist dealer relationship, and a budget that accommodates the occasional high-denomination purchase. Most collectors who attempt this focus on one denomination at a time, completing their twelve-district set in that denomination before advancing to the next.
A more accessible entry point is a single-denomination signature variety set. Collecting one Fine or Very Fine example of Tate-Mellon, Woods-Mellon, and Woods-Mills for a single denomination, say the $20, from a single district is achievable for most collectors with a modest annual budget and produces a display set that tells the complete story of Series 1928 Treasury leadership in a compact, visually compelling format.
For collectors drawn to condition rarity rather than type completion, the pursuit of gem uncirculated examples (PMG 65 EPQ or PCGS 65 PPQ and above) of Tate-Mellon notes in any denomination represents some of the most competitive specialized collecting in the small-size Federal Reserve Note field. Census populations for Tate-Mellon gems are genuinely tiny, and when they appear at major auction houses such as Heritage, Stack’s Bowers, or Lyn Knight, they routinely attract competitive bidding from multiple registry set collectors simultaneously.
Conclusion: Why Signature Varieties Reward the Attentive Collector
The signature varieties on Series 1928 Federal Reserve Notes are not merely an academic footnote. They are a tangible record of the men who administered the United States Treasury during the onset of the Great Depression, a period that fundamentally reshaped American monetary policy. Tate’s brief tenure, Woods’s steady presence across multiple Secretaries, and the Mellon-to-Mills transition each left their marks in ink on millions of pieces of paper currency. Finding and properly attributing those marks is one of the genuinely rewarding skills that separates a knowledgeable currency collector from a casual accumulator. Whether you are pursuing your first Series 1928 note or filling the last gap in a district set, understanding these signature varieties gives you a richer context for every note you examine and a sharper eye for value wherever it hides.
