Quick Answer: Error bills (also called misprint notes) can be worth $25 for minor flaws to over $100,000 for dramatic errors. The most valuable types include missing print errors, double denominations, inverted overprints, and major ink smears. Even modern bills fresh from the Bureau of Engraving and Printing can contain errors worth hundreds or thousands of dollars.
Think every dollar bill looks the same? Think again. The BEP prints billions of notes each year, and despite rigorous quality control, mistakes slip through. These error notes are some of the most sought-after collectibles in paper numismatics, and they could be hiding in your wallet right now.
What Is an Error Bill?
An error bill is any piece of U.S. currency that was printed incorrectly during the manufacturing process. Unlike fancy serial numbers or star notes, which are intentional features, error bills result from mechanical malfunctions, misfeeds, or human mistakes at the BEP.
Errors are valued because they are:
- Rare: Quality inspectors catch most mistakes before notes reach circulation
- Unique: No two errors are exactly alike
- Verifiable: Experts can authenticate genuine production errors vs. alterations
- In demand: Error collecting is one of the fastest-growing areas of paper numismatics

Missing Print Errors
A missing print error occurs when one side of a bill is completely blank or missing a layer of printing. The BEP uses intaglio presses that print in multiple stages. If a sheet misfeeds or a press malfunctions, an entire printing pass can be skipped.
What to look for:
- One side completely blank (most dramatic)
- Missing back design (more common than missing face)
- Missing third print (no serial numbers, seals, or Federal Reserve indicators)
Value examples:
| Error Description | Denomination | Approximate Value |
|---|---|---|
| Completely blank back | $1 | $300–$600 |
| Completely blank back | $20 | $500–$1,200 |
| Missing third print (no serials/seals) | $1 | $200–$500 |
| Missing third print | $100 | $500–$2,000 |
| Blank front (face not printed) | Any | $800–$5,000+ |
Double Denomination Errors
The "holy grail" of error collecting. A double denomination note is printed with one denomination on the front and a different denomination on the back (for example, a $5 face with a $10 back). These are extraordinarily rare because they require two different denomination sheets to be mixed during printing.
Only a handful of authenticated examples exist, and they regularly sell for five to six figures at auction. In 2021, a $5/$10 double denomination note sold at Heritage Auctions for over $100,000.
Inverted Overprint Errors
The overprint stage adds serial numbers, the Treasury seal, and Federal Reserve district indicators. An inverted overprint means this layer was printed upside down relative to the rest of the bill.
Value: $200–$2,500, depending on how dramatic the inversion is and the denomination.
Misaligned Printing
The most common type of error bill. Misalignment occurs when the printed image shifts off-center, causing uneven margins or the design to be noticeably crooked.
Grading misalignment value:
| Degree of Shift | Value Premium |
|---|---|
| Minor (barely noticeable) | $25–$50 |
| Moderate (clearly shifted) | $50–$200 |
| Major (design extends off edge) | $200–$500+ |
The more dramatic the shift, the more collectors will pay. A note with the portrait partially cut off by the edge is significantly more valuable than one with slightly uneven borders.
Ink Smear and Excess Ink Errors
These occur when excess ink accumulates on the printing press and transfers onto the sheet. The result can range from a small dark blotch to a dramatic streak across the entire note.
What matters:
- Size of the smear: Larger is more valuable
- Location: Smears over the portrait or key design elements attract more interest
- Color contrast: Dark ink on light areas is more eye-catching
Values range from $50 for minor smears to $1,500+ for dramatic, full-width ink streaks.
Cutting Errors (Miscuts)
Currency sheets are cut into individual notes at the end of the production process. When the cutting is misaligned, the resulting notes show uneven margins, parts of adjacent notes, or are cut at an angle.
Types of cutting errors:
- Shifted cut: Uneven margins showing part of the adjacent note
- Butterfly cut: Sheet was folded during cutting, producing an oddly shaped note
- Partial note: Significantly off-center cut leaving a dramatically undersized or oversized note
A miscut that reveals a portion of the adjacent bill's serial number or design is especially collectible.
Fold-Over Errors (Butterfly Notes)
When a corner or section of the sheet folds over before printing, part of the note receives no ink while the folded area gets printed on both sides. Unfolding the note reveals a dramatic blank area on one surface and an extra printed section on the other.
Value factors:
- Size of the fold (larger = more valuable)
- Position on the note
- Whether the fold occurred during first or second printing
Significant fold-over errors can bring $500–$3,000 at auction.
Obstruction Errors
These happen when a foreign object (a scrap of paper, tape, or other material) gets between the printing plate and the sheet. The area underneath the obstruction remains blank, leaving a distinctive unprinted patch.
Value: $75–$1,000, depending on the size and position of the blank area. An obstruction that blocks out part of the portrait or other key element is worth more.
Offset Printing Errors
An offset error occurs when a sheet fails to feed into the press on time. The inked plate presses against the impression cylinder instead of paper, and the next sheet picks up a faint mirror image from the cylinder. The result is a ghostly backward image, usually on the wrong side of the note.
Key value factors:
- Intensity of the offset image (darker = more valuable)
- Full offset (entire design transferred) vs. partial
- Which side the offset appears on
Full offsets in strong intensity can sell for $500–$2,000.
How to Identify Genuine Error Bills
Not every weird-looking bill is a genuine error. Post-production damage, deliberate alterations, and normal wear can mimic errors. Here is how to distinguish real errors from fakes.
Signs of a Genuine Error
- Consistent with production process: The error should match a known type of mechanical or feed malfunction
- Proper paper: The note uses authentic BEP cotton-linen blend paper with embedded security features
- Correct ink: Colors and ink types match the denomination and series
- No evidence of tampering: No chemical washing, scraping, or added substances
Common Fakes to Avoid
| Fake Error Type | How to Spot It |
|---|---|
| Washed/bleached notes | Paper feels different; security features may be damaged |
| Cut-and-paste alterations | Examine edges under magnification for splicing |
| Chemically removed ink | Uneven paper surface; security thread may be affected |
| Added ink/stamps | Ink sits on top of paper rather than being absorbed |
| Trimmed margins (fake miscut) | Measure the note; genuine notes are 6.14" x 2.61" |
Authentication Resources
For error bills potentially worth $200 or more, consider professional authentication:
- PMG (Paper Money Guaranty): The leading third-party currency grading service. PMG encapsulates and grades error notes with detailed descriptions.
- PCGS Currency: Another respected grading service that authenticates error notes.
Graded and authenticated error notes sell for significantly more than raw (ungraded) examples because buyers have confidence in their authenticity.
How Condition Affects Error Bill Values
Even among error notes, condition matters. An uncirculated error bill is worth substantially more than a heavily circulated one.
| Condition | Value Multiplier (vs. VF baseline) |
|---|---|
| Gem Uncirculated (65+) | 3x–5x |
| Choice Uncirculated (63-64) | 2.5x–4x |
| Uncirculated (60-62) | 2x–3x |
| About Uncirculated (50-58) | 1.5x–2x |
| Very Fine (25-35) | 1x (baseline) |
| Fine or lower | 0.5x–0.75x |
The exception: truly dramatic errors (double denominations, full missing prints, large fold-overs) hold strong value even in lower grades because rarity outweighs condition.
How to Check Your Bills for Errors
Quick 60-Second Inspection
Follow these steps every time you get cash back:
- Check both sides: Hold the bill up and flip it over. Does the printing look complete and properly aligned on both sides?
- Compare margins: Are the borders even on all four sides? Noticeably uneven margins may indicate a cutting or alignment error.
- Look at serial numbers and seals: Are they present, properly positioned, and right-side up?
- Examine the ink: Any unusual smears, extra marks, or areas where ink seems missing?
- Feel the paper: Any unusual folds, extra thickness, or attached foreign material?
- Scan with CashScan: Use the app to instantly identify your bill's series, verify its features, and flag any irregularities worth investigating further.
Building an Error-Hunting Habit
The best error hunters check every bill that passes through their hands. Consider these strategies:
- Ask for new bills at the bank: Fresh notes from the BEP are more likely to contain undetected errors than heavily circulated bills
- Request $2 bills and less common denominations: These have smaller print runs, so the odds of finding errors per bill examined are slightly higher
- Check strap edges: When banks receive banded straps of new bills, errors are sometimes found on the notes at the top or bottom of the strap
- Use good lighting: Some errors (light ink smears, faint offsets) are only visible under bright, direct light

Frequently Asked Questions
Are error bills legal to own?
Yes. Error bills are genuine U.S. currency produced at the BEP. They are legal to own, collect, buy, and sell. They remain legal tender at face value regardless of the error.
How common are error bills?
The BEP's quality control catches the vast majority of misprints before they leave the facility. Estimates suggest fewer than 1 in every 100,000 notes that reach circulation contains a noticeable error, making genuine error bills quite scarce.
Can I find error bills in normal circulation?
Absolutely. While many errors are caught at the BEP, some make it into general circulation. Checking your change carefully, requesting new bills from banks, and examining large quantities of currency are all proven strategies for finding errors.
Should I spend a bill I think has an error?
No. If you suspect a bill has a printing error, set it aside immediately. Even minor errors can be worth $25–$100 above face value, and major errors could be worth hundreds or thousands. Store the note in a protective sleeve until you can have it evaluated.
How do I get an error bill graded?
Submit the note to PMG or PCGS Currency through their online submission process or at a currency show. Grading fees typically range from $20–$65 per note depending on the declared value and turnaround time.
What's the difference between an error and a variety?
An error is a one-time production mistake (ink smear, miscut, missing print). A variety is a consistent difference across an entire print run, such as a different plate position or micro-printing change. Both can be collectible, but dramatic errors tend to command higher prices.
Do error bills need to be in perfect condition to be valuable?
Not necessarily. Dramatic errors like missing prints, double denominations, and large fold-overs hold strong value even in circulated condition. For common errors like minor misalignments, condition plays a bigger role in determining value.
Conclusion
Error bills represent one of the most exciting corners of paper money collecting. Every bill you handle is a potential discovery, from a $50 misalignment to a five-figure missing print. The key is knowing what to look for and checking your cash carefully.
Start by examining every bill that passes through your hands. Look for uneven margins, missing elements, ink irregularities, and anything that seems "off" compared to a normal note. Even circulated errors found in everyday change can be worth meaningful money to collectors.
