Pick up any circulated dollar bill and you already understand something fundamental about how US currency works: both sides carry ink, intricate design, and layers of security. So when a note escapes the Bureau of Engraving and Printing (BEP) with one side completely blank, it stops collectors cold. These are not smeared prints or misaligned seals. They are notes that entirely missed a major press run, producing a white, featureless expanse where portraits, vignettes, or treasury seals should be. Missing face and missing back printing errors are among the most visually arresting, historically significant, and financially valuable error notes in all of United States paper money collecting.
How the BEP Printing Process Creates These Errors
To appreciate why a blank-sided note is so remarkable, you need to understand the BEP’s multi-stage intaglio and offset printing process. Modern Federal Reserve Notes go through at least three major press runs. The first applies the back design using offset lithography. The second applies the face design, including the Federal Reserve district seal, portrait, and denomination numerals, also initially via offset. A third pass runs the sheet through intaglio presses, which apply the raised ink that gives genuine currency its characteristic feel. Overprinting adds the black Federal Reserve seal, serial numbers, and the green Treasury seal in a final stage.
A missing back printing means a sheet of currency paper was fed directly into the face printing press without ever passing through the back press. The result is a note with a fully printed face and a completely blank reverse. A missing face printing, conversely, means a sheet received the back design but somehow bypassed the face press entirely, leaving no portrait, no denomination text on the face, and no Federal Reserve identifiers. Both scenarios represent a failure of the BEP’s quality control checkpoints, which is precisely what makes them so rare. The BEP uses ultraviolet detection, human inspection, and automated scanning to catch misprints before they leave the building, yet a small number of these notes slip through every few years.
Always examine the blank side of an alleged missing print note under ultraviolet light. Genuine BEP currency paper contains red and blue security fibers that fluoresce under UV. If the blank side shows these fibers, that is a strong indicator of authenticity. Bleached notes, a common counterfeit of this error type, will often show chemical residue or missing fiber patterns under UV examination.
Missing Back vs. Missing Face: Which Is Rarer?
Collectors and dealers frequently debate which variety is truly scarcer. The honest answer is that missing face printings appear less frequently in the marketplace and typically command higher prices. The logic is straightforward: the back design is applied first. A sheet missing its back print must then somehow pass through the face printing station undetected, accumulate its serial numbers and seals, and exit the facility without triggering inspection alerts. Each additional press run represents another opportunity for quality control to catch the error. By contrast, a sheet that receives a back print but misses the face press has already passed one major checkpoint.
Heritage Auctions and Stack’s Bowers records from 2015 through 2023 show missing face printings consistently selling for 20 to 40 percent premiums over comparable missing back printings in the same series and denomination. A PMG 64 EPQ missing face on a Series 1999 $10 Federal Reserve Note sold at Heritage in January 2022 for $8,400. A comparable missing back printing from the same series in PMG 63 brought $5,750 at the same auction house six months later.
Notable Series and Denominations in Collector Hands
Missing print errors have been documented across nearly every modern Federal Reserve Note series, but certain series appear with disproportionate frequency in error note catalogs and auction records. The Series 1988A $1 notes, particularly those from the Atlanta (F) and Chicago (G) Federal Reserve districts, include several confirmed missing back examples that entered the hobby through bank tellers who recognized their significance. The Series 1995 $1 notes from multiple districts generated a small cluster of missing back errors that collectors began documenting seriously around 1998.
Higher denomination missing prints are dramatically scarcer in absolute terms simply because fewer high-denomination notes are printed. A missing back on a Series 1993 $100 Federal Reserve Note, signed by Secretary of the Treasury Lloyd Bentsen and Treasurer Mary Ellen Withrow, is a genuine condition rarity. Only a handful of confirmed examples exist across all major third-party grading services. The most spectacular confirmed example of a modern large denomination blank-sided note remains a Series 1969C $100 Federal Reserve Note with a missing face, which appeared in a Smythe auction in 2004 and realized $18,000 in PMG 58 grade.
When researching missing print errors, consult the Bart’s Comprehensive Catalog of United States Paper Money Errors by Frederick J. Bart. First published in 1993 and updated in subsequent editions, this catalog assigns specific catalog numbers to error types and provides population data that is invaluable when assessing rarity and pricing. The PMG and PCGS population reports also list certified error notes by type and can help you understand how many examples of a specific series and denomination have been authenticated.
Authentication Challenges: Bleached Notes and Other Fakes
The single greatest authentication challenge facing collectors of blank-sided notes is the bleached note. Criminals have long used chemical processes to strip the ink from genuine Federal Reserve Notes, leaving a blank piece of authentic BEP currency paper. This paper can then be reprinted with counterfeit designs or sold outright as a missing print error. The authentication problem is serious enough that major error note dealers refuse to purchase any blank-sided note without a PMG or PCGS certification holder.
Third-party graders detect bleached notes through several methods. Chemical bleaching alters the cellulose structure of the cotton-linen BEP paper in ways detectable under magnification. Genuine missing print errors retain the original paper sizing and surface texture on the blank side. Bleached notes often show microscopic fiber disruption, slight dimensional changes, or chemical residue that trained graders identify immediately. Beyond UV and chemical analysis, graders also examine serial number positioning, seal placement, and sheet registration marks to verify the note’s provenance as an unaltered production error.
Partial Missing Prints and Related Errors
Collectors should also be aware of partial missing prints, sometimes called insufficient inking errors or kiss prints, which occur when a printing plate has depleted ink or makes only partial contact with the sheet. These are distinct from true missing print errors in that some design elements appear on the affected side, even if faint or incomplete. They are generally less valuable than complete missing print errors, though dramatic examples with 70 to 90 percent of the face or back absent can still command prices in the $1,000 to $4,000 range depending on denomination and grade.
A related but distinct error is the offset printing error, where wet ink from one side transfers to the face of another sheet during stacking. These produce a ghostly, mirror-image impression on one side and are sometimes confused with partial missing prints by inexperienced buyers. True offsets show a reversed impression, while genuine missing prints show either a completely blank surface or an incomplete but correctly oriented design.
If you are buying a blank-sided note at a show or from a private seller, always ask about the note’s provenance chain. Error notes that came directly from bank employees, have documented discovery stories, or appeared in early auction catalogs from the 1990s and early 2000s carry a significantly stronger authentication pedigree than notes with no paper trail. Provenance does not replace third-party certification, but it meaningfully supports it.

Grading Considerations Specific to Blank-Sided Notes
Grading a missing print error involves some nuances that do not apply to normal currency. PMG and PCGS both evaluate the printed side using standard grading criteria: centering, fold count, edge wear, and soiling. However, the blank side receives equal scrutiny for evidence of alteration. Both services use the designation “Missing Back Printing” or “Missing Face Printing” within their error note classification system, and notes receiving these designations in grades of 63 and above with the EPQ (Exceptional Paper Quality) qualifier are particularly prized.
One important nuance: the blank side of a genuine missing print note will often show very faint offset ghost images from the printed side or from adjacent sheets during storage. This is normal and expected. A perfectly pristine blank side with no ghost impressions at all can sometimes raise questions, though it is entirely possible in a well-preserved example. Graders evaluate the totality of evidence rather than using any single indicator as definitive.
Building a Collection: Entry Points and Strategy
For collectors entering the error note market, Series 1995 and Series 2003A missing back $1 Federal Reserve Notes represent the most accessible entry point. These notes, while still legitimately rare in the broader context of US currency, appear at major shows and in auction catalogs with enough frequency that prices remain in the $500 to $1,500 range for mid-grade certified examples. The $1 denomination also means that authentication standards are well established and population data is more robust than for scarce higher denominations.
Advanced collectors building a type set of missing print errors by denomination should be prepared for a long-term pursuit. Assembling certified examples across $1, $2, $5, $10, $20, $50, and $100 denominations could take a decade or more given how infrequently high-denomination examples surface. The $2 Federal Reserve Note missing print error is particularly elusive because of the relatively low print volumes for that denomination historically. No confirmed missing face example on a $2 FRN has appeared at major auction in the past fifteen years, making it a potential condition rarity of the highest order.
Subscribe to auction house email alerts from Heritage Auctions, Stack’s Bowers, and Lyn Knight Currency Auctions with search terms targeting error notes. Missing print errors rarely appear more than two or three times per year at major venues, and advance notification gives you time to research comparables, review population data, and set a confident bidding limit before the sale date.
The Market Today and What Drives Value
The error note market has strengthened significantly since 2015, driven by growing collector interest, better third-party certification infrastructure, and increased visibility through online auction platforms. Missing print errors have tracked this broader appreciation, with auction records from 2020 through 2023 frequently exceeding pre-pandemic hammer prices by 30 to 50 percent for comparable notes. The Series 1993 $20 missing face examples that sold in the $3,500 to $4,500 range in the early 2010s now routinely exceed $7,000 in certified mid-grade condition.
Condition remains the dominant value driver, followed closely by denomination and error type. District matters less for missing print errors than for other Federal Reserve Note varieties, though certain district and series combinations with independently documented low populations command premiums. Notes that have appeared in major reference works, including Bart’s catalog or the IBNS Journal, carry additional collector cachet that can push realized prices above population-adjusted market levels.
Conclusion
Missing face and missing back printing errors stand at the intersection of technical numismatic interest, dramatic visual impact, and genuine scarcity. They are notes that should not exist, products of a manufacturing process specifically engineered to prevent their creation, yet they surface reliably enough that a dedicated collector can realistically acquire them. Whether you are searching for your first certified error note or hunting a $100 denomination missing face to complete an advanced type set, understanding the printing process, authentication standards, and market history covered here will help you buy with confidence, price with accuracy, and appreciate each example for the accidental marvel it truly is.
