Pick up a well-worn 1880 $1 United States Note and you are holding something extraordinary: a direct obligation of the United States government, not a Federal Reserve liability, not a national bank obligation, but a promise from the Treasury itself backed by the full faith and credit of the nation. The red Treasury seal stamped boldly on the face was not merely decorative. It was a legal declaration, a visual shorthand for a currency class that existed alongside, competed with, and ultimately outlasted almost every other nineteenth-century note type. United States Notes, formally authorized by the Legal Tender Acts of 1862, 1863, and 1878, were issued continuously in one form or another until 1971, spanning more than a century of American economic life. What survives today ranges from common pocket change to museum-caliber rarities worth six figures at auction.
The Civil War Origins: Large-Size Issues, 1862 to 1869
When Confederate forces fired on Fort Sumter in April 1861, the United States Treasury was effectively bankrupt. Customs revenues had collapsed, bond sales moved sluggishly, and the army needed to be paid. Secretary of the Treasury Salmon P. Chase, working with Congress, pushed through the Legal Tender Act of February 25, 1862, authorizing $150 million in non-interest-bearing Treasury notes that would be legal tender for all debts public and private, except import duties and interest on the public debt. Those two exceptions were significant: the government itself would not fully accept its own paper for certain obligations, a quiet acknowledgment of the note’s forced-currency nature.
The First Obligation series of 1862 appeared in denominations of $1, $2, $5, $10, $20, $50, $100, $500, and $1,000. The American Bank Note Company and the National Bank Note Company shared printing duties. These notes carry the signatures of Treasurer Francis E. Spinner and Register Lucius E. Chittenden, or in later 1862 printings, Register Milton Otis or John Colby. The face designs were relatively austere by later standards: the $1 featured a portrait of Salmon Chase himself, a choice Chase allegedly orchestrated personally, while the $5 carried a vignette of the Treasury building and a portrait of Alexander Hamilton.
The Second Obligation reverse, introduced in late 1862 on the $1 and $2 denominations, replaced the blunt legal tender clause language with the more familiar obligation wording. Collectors prize first-obligation notes for their historical immediacy. A VF-20 example of the 1862 $1 Chittenden-Spinner with the first obligation reverse routinely brings $300 to $600 at auction, while Choice Uncirculated examples can approach $3,000 or more.
When examining 1862 and 1863 United States Notes, check the reverse obligation clause carefully. The “First Obligation” reverse uses different wording than the “Second Obligation” reverse introduced later that year on the $1 and $2. Both varieties exist and both are collectible, but first-obligation notes command a meaningful premium in any grade.
The Series of 1869: The Rainbow Notes
The Series of 1869 represents one of the most beloved redesigns in American currency history. Often called “Rainbow Notes” by collectors because of their vivid, multicolored reverses, these large-size United States Notes introduced portrait placements and design conventions that influenced American currency for decades. The $1 note shifted to a portrait of George Washington at center and Columbus in Sight of Land at left. The $10 carried Daniel Webster and Pocahontas. The $100 bore Abraham Lincoln and the architect of the Capitol.
Signatures on 1869 notes pair Treasurer Francis Spinner with Register John Allison. These notes are scarcer than their successors in the 1870s and 1880s series, particularly in higher grades. The $500 and $1,000 denominations from 1869 are genuine rarities today, with population reports from PCGS and PMG showing only handfuls of examples across all grades. A PMG VF-30 example of the 1869 $1,000 United States Note sold for over $200,000 at a major 2019 auction.
The 1870s Through 1880s: Consolidation and Series Proliferation
Between 1870 and 1880, the Bureau of Engraving and Printing gradually took over production from private bank note companies, and United States Notes went through a succession of signature and design changes that created a complex but rewarding collecting landscape. The Series of 1875 and 1878 introduced colorized counters and spiked seals on many denominations. The Series of 1880 brought the “large brown seal” and later the “large red seal” varieties that are among the most visually striking of all large-size notes.
The 1880 series is particularly important because it spans an enormous range of signature combinations. The $1 note alone exists with at least six distinct Treasurer-Register signature pairings, from Scofield-Gilfillan through Tillman-Morgan. Each combination represents a distinct variety with its own rarity profile. The Rosecrans-Huston combination on 1880 notes, identifiable by its large brown seal, is notably scarcer than the later red-seal varieties.
The signature combinations on Series 1880 United States Notes are crucial to value. Before purchasing any 1880 large-size Legal Tender note, cross-reference the Treasurer and Register signatures against a population report from PCGS Currency or PMG. Some combinations are genuinely rare across all grades, while others are relatively common in Fine to Very Fine.
High-Denomination Notes: The $500 to $10,000 Issues
United States Notes were issued in denominations reaching $10,000, though these highest values were produced in tiny quantities intended primarily for interbank settlements rather than public circulation. The $5,000 United States Note of 1878 bearing James Madison’s portrait and the $10,000 note of the same series with Andrew Jackson are among the rarest pieces of American paper money in existence. Fewer than a dozen examples of the $10,000 1878 United States Note are confirmed to survive, and most reside in institutional collections including the Smithsonian.
The $500 and $1,000 denominations, while still rare, appear at auction with enough regularity that determined collectors can realistically aspire to ownership. The 1880 $500 note bearing a portrait of General Joseph Mansfield, for example, appears perhaps three to five times per year across major auction houses. Budget accordingly: even heavily circulated examples in Good-4 to Fine-12 grades regularly bring $8,000 to $20,000.
Small-Size United States Notes: 1928 Through 1966
The currency reform of 1928 reduced all American paper money to the current small size and brought United States Notes into the modern era. The Series of 1928 Legal Tender notes were issued in $1, $2, $5, and higher denominations. The $1 United States Note had a brief run: the Series 1928 $1 with the Woods-Mellon signature combination was issued only from the Federal Reserve Bank of Boston through the Twelfth District, and the denomination was discontinued after modest production. Total production for the Series 1928 $1 Legal Tender note was approximately 1,872,012 notes, making it a genuine key in small-size collecting.
The $2 United States Note in small size ran continuously through the Series of 1963-A, with the red seal distinguishing it immediately from any other small-size note. The Series 1928-B $2 note with the Woods-Mills signature combination is the scarcest of the common small-size $2 varieties in uncirculated condition. The Series 1953 and 1963 $2 notes are quite common in circulated grades and represent accessible entry points for new collectors.
The $5 United States Note in small size ran through the Series of 1963, with the red seal on Lincoln’s portrait note creating a striking contrast to the familiar green-seal Federal Reserve variety. The Series 1928 $5 Legal Tender note is the key date of the run, with the Woods-Mellon signature pairing and a relatively low print run compared to later issues.
Small-size $2 United States Notes from the Series 1928 through 1963-A are highly collectible as a complete type set. Assembling all major series in Extremely Fine or better condition is achievable on a modest budget for most issues, with only the Series 1928-B and 1928-D presenting real challenges. Look for original crisp examples with bright red seals and strong serial numbers, as the red ink is prone to fading on notes that were stored in damp or acidic environments.
The Final Chapter: Series 1966 and 1966-A $100 United States Notes
By the mid-1960s, United States Notes were being phased out quietly. The $1 had been discontinued after 1928, the $2 ended with Series 1963-A, and the $5 ended with Series 1963. Only the $100 denomination remained, kept alive largely to satisfy the statutory requirement that a minimum amount of United States Notes remain in circulation. The Series of 1966, bearing the signatures of Treasurer Granahan and Secretary Fowler, was printed in relatively modest quantities. The Series 1966-A, with Signatures of Treasurer Elston and Secretary Kennedy, represented the final United States Note series ever produced.
Both the 1966 and 1966-A $100 Legal Tender notes are collectible in their own right. The 1966-A in particular had a very small print run of approximately 768,000 notes, and finding examples in grades above MS-63 requires patience. These notes were legal tender until the Treasury officially retired them from circulation in August 1971, though they technically remain valid legal tender to this day.
What Survives Today: Survival Estimates and Population Data
Survival rates for United States Notes vary enormously by series and denomination. Large-size notes from 1862 through 1923 exist in widely varying quantities: common small denominations from the 1880s series may have tens of thousands of surviving examples across all grades, while high-denomination notes from the 1860s and 1870s may survive in populations of fewer than 50 certified examples. PMG and PCGS Currency maintain population reports that are invaluable for modern collectors, though it is important to remember that population reports count certifications, not unique notes, and resubmissions can inflate apparent rarity.
For small-size notes, survival is generally higher because the notes are more recent and collectors began saving them earlier. Nearly all Series 1963 and 1963-A $2 and $5 United States Notes that entered collector hands remain in existence. The challenge for modern collectors is finding original, problem-free examples rather than notes that have been cleaned, pressed, or repaired, practices that significantly reduce value.
| Series / Date | Denomination | Approx. Print Run or Survivors | Rarity |
|---|---|---|---|
| 1862 First Obligation | $1 (Chittenden-Spinner) | Est. several thousand survivors | Scarce |
| 1869 Rainbow | $1,000 | Fewer than 20 known | Key Date |
| 1878 | $10,000 | Fewer than 12 known | Key Date |
| 1880 Rosecrans-Huston | $1 (Large Brown Seal) | Est. 500 to 1,500 survivors | Scarce |
| 1880 | $500 (Tillinghast vignette) | Fewer than 75 certified | Rare |
| 1928 Small-Size | $1 (Woods-Mellon) | 1,872,012 printed; few uncirculated survivors | Key Date |
| 1928-B Small-Size | $2 (Woods-Mills) | 9,001,632 printed; scarce in CU | Scarce |
| 1963 Small-Size | $2 (Granahan-Dillon) | Over 15 million printed; common | Common |
| 1966 | $100 (Granahan-Fowler) | Approx. 768,000 to 1.2 million | Scarce |
| 1966-A | $100 (Elston-Kennedy) | Approx. 768,000; few gem survivors | Rare |
Building a Collection: Strategies for Every Budget
United States Notes offer entry points at virtually every price level. A beginning collector can assemble a representative type set of small-size red seals covering the $2 and $5 denominations across all series from 1928 through 1963-A for under $500 in circulated grades. Moving into large-size notes, the 1880 series $1 notes in Very Good to Fine condition are available for $75 to $200 depending on the signature combination, making them accessible introductions to nineteenth-century American paper money.
Advanced collectors tend to focus on either completeness within a single denomination, attempting to acquire every signature variety and series of the $1 or $2 United States Note for example, or on high-grade examples of key dates. The latter strategy requires significant capital but yields collections of exceptional numismatic importance. Third-party grading from PMG or PCGS Currency is essentially mandatory for any note above $500 in value, both for authentication and for resale liquidity.
One underappreciated collecting area involves star notes, or replacement notes, within the small-size United States Note series. Star serial numbers on $2 and $5 Legal Tender notes can be dramatically scarcer than regular serials for the same series. The Series 1928 $5 star note, for example, is considered extremely rare in any grade and commands a substantial premium over the already-scarce regular issue.
Conclusion: A Century of Red Seals
From the emergency printing rooms of wartime Washington in 1862 to the quiet retirement of the last Series 1966-A $100 notes in 1971, United States Notes represent one of the longest continuous runs in American monetary history. They were created in crisis, criticized as inflationary, defended as constitutional, and ultimately outlived nearly every contemporary currency type. The red seal that identifies them is more than a design choice. It is the mark of a direct government promise, a promise that remains technically valid on every surviving note today. For collectors, that combination of historical depth, visual variety, and genuine rarity across multiple denominations makes United States Notes one of the most rewarding areas in the entire field of American numismatics.
