Pull a Series 1950 $20 Federal Reserve Note out of your collection and flip it over. Now measure the white margin between the outer edge of the green printed design and the edge of the paper itself. If you’ve never done this, you’re not alone. The difference between a Wide Back and a Narrow Back on this series is one of the most consistently overlooked plate varieties in mid-century Federal Reserve Note collecting, yet it has real implications for catalog value, plate history, and the story of how the Bureau of Engraving and Printing managed its production workflow during the late 1940s and early 1950s. This is the kind of detail that separates a casual accumulator from a serious collector.
Background: Why the Back Design Changed
The $20 Federal Reserve Note issued under Series 1950 carried the familiar portrait of Andrew Jackson on the obverse and the White House vignette on the reverse, a design pairing that had been established with the Series 1928 small-size notes and would continue essentially unchanged for decades. What collectors often fail to appreciate is that the reverse printing plates used by the BEP were not monolithic. They were manufactured, used, worn, and replaced across the production lifetime of a given series, and slight differences in how those plates were laid out relative to the sheet margins resulted in the Wide Back and Narrow Back distinctions we document today.
The change is rooted in practical BEP plate management. Early production plates for the 1950 series were laid out with slightly more generous marginal allowances, consistent with production norms carried over from the late 1940s. As new plates were introduced into the rotation, the layout tightened. The result is that notes from early plate cycles show a visibly wider border of uninked paper around the green reverse design, while later printings show the design sitting much closer to the note’s perimeter. This is not a printing error or a miscut. It is a deliberate, if unannounced, plate specification adjustment.
To distinguish Wide Back from Narrow Back at a glance, lay the note face-down on a flat surface and examine all four margins simultaneously. On a genuine Wide Back, you should see a noticeably even border of white paper that feels “airy” around the design. On a Narrow Back, the White House vignette and surrounding green scrollwork appear to push closer to the note’s edges. A simple jeweler’s loupe or 5x magnifier is sufficient for this inspection.
How to Identify Each Variety
Identification begins with a careful look at the reverse. On the Wide Back variety, the margin between the outermost printed element of the back design and the physical edge of the note measures approximately 3 millimeters or slightly greater when the note is well-centered. Because hand-cutting tolerances at the BEP were not perfectly uniform, there is some variation within Wide Back examples, but the overall impression is one of generous white space framing the design. The green ink of the reverse design feels contained, almost understated.
The Narrow Back variety presents a different visual weight. Here, the margin shrinks to roughly 2 millimeters or less on one or more sides, and on notes that also experienced a slight cutting shift, the design can appear to nearly touch the edge. The scrollwork borders and the outer geometric guilloche patterns of the White House vignette are noticeably closer to the paper perimeter. Interestingly, the face of the note is not affected by this change. Jackson’s portrait, the Federal Reserve Bank seal, the Treasury seal, and the serial numbers appear on plates that were managed separately from the back plates, so there is no corresponding face variety to cross-reference.
It is worth noting that centering plays a complicating role. A Wide Back note with an off-center cut can appear to have a narrow margin on one side, potentially causing misidentification. The most reliable approach is to measure all four margins and average them, or to compare the note against a confirmed example from a reference collection. The Oakes-Schwartz reference “Standard Guide to Small-Size U.S. Paper Money” addresses the distinction, and the Friedberg catalog acknowledges the variety within the broader #2060 through #2060-G numbering range covering the twelve Federal Reserve Bank districts.
Centering can fool you. Before attributing a Narrow Back, measure all four margins with a millimeter ruler or digital calipers. If three margins are consistent and one is tight due to an off-center cut, you may actually have a Wide Back. True Narrow Backs will show compressed margins across the majority of the design perimeter, not just on a single side.
Which Districts and Signature Combinations Are Affected
The Series 1950 $20 FRN was produced for all twelve Federal Reserve Bank districts: Boston (A), New York (B), Philadelphia (C), Cleveland (D), Richmond (E), Atlanta (F), Chicago (G), St. Louis (H), Minneapolis (I), Kansas City (J), Dallas (K), and San Francisco (L). The Wide Back variety is primarily associated with earlier production runs across most districts, while the Narrow Back becomes predominant in later printings. However, the transition point differs by district based on when each bank requisitioned new note supplies and which plate cycles were active at the time of printing.
The Series 1950 carries the signature combination of Treasury Secretary John W. Snyder and Treasurer Georgia Neese Clark. This pairing dates from notes delivered starting in 1950 and continuing into the early part of the decade. The subsequent 1950-A series introduced the Priest-Humphrey signature combination (Ivy Baker Priest as Treasurer, George M. Humphrey as Secretary), and the Wide Back variety effectively disappears by this point in most districts, though transitional examples from early 1950-A plate use are occasionally documented.
New York (B) and Chicago (G) districts, being the highest-volume issuers, provide the greatest number of examples for study and are the most accessible for building a comparative reference set. San Francisco (L) and Minneapolis (I) printings in Wide Back configuration are considerably scarcer due to lower overall print volumes for those districts under the base 1950 series.
Print Runs and Relative Scarcity
Aggregate print run data for Series 1950 $20 notes shows that total production across all districts ran into the hundreds of millions of notes, making the series broadly common in circulated grades. The Wide Back variety, being tied to earlier plate cycles, represents a minority of total production. Reliable district-by-district plate attribution data is incomplete in public records, but collector population reports from PCGS Currency and PMG suggest that certified Wide Back examples are encountered at roughly a 1:4 or 1:5 ratio compared to Narrow Back examples in the market, depending on district.
Star note replacements within the 1950 series add another layer of desirability. A Wide Back star note from a low-volume district commands a meaningful premium over a standard Wide Back, and these are genuinely rare in any grade above Very Fine. Star notes were produced in smaller quantities for each district as replacements for defective notes, and the probability that a given star note falls into the Wide Back production window is correspondingly lower.
Star notes from low-volume districts such as Minneapolis (I) and Dallas (K) in the Wide Back variety are legitimately scarce and undervalued relative to their true rarity. If you encounter one in a dealer’s stock labeled simply as “1950 $20 Star,” examine the back margins before passing it by. A Wide Back star from one of these districts in VF or better condition is a genuine find worth pursuing.
Grading Considerations and Eye Appeal
From a grading standpoint, the Wide Back variety benefits from the fact that its more generous margins can actually contribute to better apparent centering scores at PCGS Currency and PMG, both of which weight centering as part of their overall grade assessment for notes submitted in holder grades of 64 and above. A Wide Back example with naturally balanced margins and strong paper quality can achieve a Choice Uncirculated 64 or Gem 65 designation more comfortably than a Narrow Back example that sits close to the design boundaries. This is not a universal rule, but it is a factor worth considering when submitting notes for third-party grading.
Ink quality on the reverse is another grading factor that intersects with variety identification. Wide Back examples from early plate cycles can show slightly richer, more deeply embossed green ink, a byproduct of using fresher plates with more pronounced relief. As plates wore through successive print runs, ink distribution could become marginally flatter. This is a subtle distinction that even experienced graders may not flag in their holder notes, but it contributes to the superior eye appeal often reported for high-grade Wide Back examples.
| District | Variety | Est. Relative Availability | Rarity |
|---|---|---|---|
| New York (B) | Wide Back, Regular | High volume district, moderate survivors | Scarce |
| New York (B) | Wide Back, Star (*) | Small fraction of star run | Rare |
| Chicago (G) | Wide Back, Regular | High volume, moderate survivors | Scarce |
| Chicago (G) | Wide Back, Star (*) | Low star production in Wide Back window | Rare |
| Minneapolis (I) | Wide Back, Regular | Low district volume overall | Rare |
| Minneapolis (I) | Wide Back, Star (*) | Extremely low production | Key Date |
| Dallas (K) | Wide Back, Regular | Low-mid district volume | Rare |
| Dallas (K) | Wide Back, Star (*) | Extremely low production | Key Date |
| San Francisco (L) | Wide Back, Regular | Moderate district, limited Wide Back window | Rare |
| All Districts | Narrow Back, Regular | Majority of total series production | Common |
Current Market Values and Where to Find Them
In the current market, a circulated Series 1950 $20 FRN in Fine to Very Fine condition from a major district trades at modest premiums over face value, typically in the $25 to $45 range for common Narrow Back examples. A Wide Back example in the same grade from a high-volume district such as New York or Chicago commands a premium that can push values to $60 to $100 depending on the specific district and eye appeal. In Uncirculated grades, the spread widens further. A Narrow Back in PCGS or PMG 64 might bring $80 to $150, while a Wide Back in comparable grade from the same district can achieve $175 to $300 at major currency auction houses including Heritage Auctions, Stack’s Bowers, and Lyn Knight Currency Auctions.
Star note Wide Backs in Uncirculated condition from low-volume districts are sold as individual rarities rather than by formula, with realized prices depending heavily on the specific district, the population report data at time of sale, and the competitive appetite of advanced collectors in the room. Star Wide Backs from Minneapolis and Dallas in grades of 63 or better have historically realized between $400 and $900 at major auction, with occasional outliers pushing higher when two serious collectors compete for the same note.
Before paying a Wide Back premium, ask the dealer or auction house for close-up photographs of all four reverse margins. Many general currency dealers list Series 1950 $20 notes without identifying the variety at all, which means genuinely rare Wide Back examples are sometimes priced at Narrow Back levels. Due diligence here can result in real savings and genuine variety pickups at below-market prices.
Building a Type Set Around This Variety
For collectors who enjoy the pursuit of complete variety sets, the Series 1950 $20 Wide Back offers a structured collecting goal that does not require a limitless budget. A practical approach is to target one Wide Back example per Federal Reserve district in a consistent grade, such as Very Fine 30 or Extremely Fine 40. This twelve-note set, if assembled with confirmed Wide Back attribution and attractive, original paper, represents genuine numismatic scholarship assembled note by note. For advanced collectors, adding the corresponding Narrow Back for each district creates a twenty-four note comparison set that illustrates the plate transition across the entire series.
The Oakes-Schwartz “Standard Guide to Small-Size U.S. Paper Money” remains the primary print reference for attribution, and the online resources at the National Numismatic Collection documentation project and the PCGS Currency and PMG population reports provide real-time data on how many confirmed examples have been certified by district and variety. These tools are invaluable for setting realistic completion goals and understanding which pieces will require patience versus which can be sourced through normal dealer channels.
Conclusion: The Margin That Matters
The Wide Back versus Narrow Back distinction on the Series 1950 $20 Federal Reserve Note is exactly the kind of detail that rewards careful study. It does not announce itself. It will not appear in a general currency price guide without specific attribution. But for collectors willing to measure, compare, and document, it represents a legitimate and historically grounded variety with real market differentiation. The BEP’s plate management decisions from seven decades ago left a permanent record in the margins of these notes, and that record is still readable today in the notes passing through dealer cases and auction lots every week. The collectors who recognize it hold a genuine advantage.
