Rare 1850 Half Dollar Errors (List & Pictures)
A missing elbow fold and repeated shield lines can be subtle clues on an 1850-O half dollar. The highest supplied sale among these 1850 half dollar errors is a Philadelphia repunched date that brought $5,520 in May 2025.
Estimated values span $250–$6,000 across the stated grades. Follow the front clothing, shield, and date, then turn to the mintmark and the area beside the eagle’s shield.
| Observation | Inspection area | Feature | Estimated value |
|---|---|---|---|
| The elbow fold is absent | Clothing below the elbow on O coins | Reported No Drapery | $250–$800 |
| Repeated upper shield lines | Front shield on an O coin | Reported doubled die obverse | $300–$1,000 |
| Extra pieces of 5 or 0 | Philadelphia date | Repunched date | $1,000–$6,000 |
| A second curved O outline | Mintmark below the eagle | Repunched mintmark | $500–$1,500 |
| Faint extra shapes beside the shield | Philadelphia reverse | Clashed dies | $2,500–$5,000 around MS63 |
O marks New Orleans; Philadelphia halves have no mint letter. Original unworn specifications are approximately 13.36 grams and 30.6 mm, with a grooved edge.
1. 1850 Half Dollar The Fold Below the Elbow Is Missing: Reported No Drapery Error
The 1850-O report concerns loss of a shallow clothing fold through excessive die polishing. A die is the steel stamping tool, and polishing away part of its design prevents later coins from receiving that detail.
This is distinct from the original No Drapery design introduced in 1839. An 1850 coin also can lose the elbow fold through ordinary circulation wear.
How to Identify
Compare a normal 1850-O with similar wear. If the arm and surrounding folds are broadly flattened too, wear may explain the missing detail.
Examine the elbow under changing light for scraping or smoothing after minting. Abrasion can remove an existing fold while disturbing the nearby surface.
The useful contrast is a missing fold surrounded by otherwise readable local detail. Confirm the O and keep the broader clothing in the photograph rather than isolating an empty patch.
What It’s Worth
Estimated range: $250–$800 for circulated coins convincingly matching the reported polishing effect. Ordinary 1850-O comparisons include $336 at XF45 in April 2025 and $512 at AU53 in July 2026.
The year guide supplies the No Drapery report but identifies no certified specimen or completed sale specifically for the absent fold. The prices compare moderate and light wear on the underlying coin.
2. 1850 Half Dollar Shield Lines and Its Border Repeat: Doubled Die Obverse Error
A collector describes doubling in the upper vertical shield lines and along the shield’s edge on an 1850-O. The observation appears in the owner’s registry description.
A doubled die contains repeated design before striking and can copy the same extra shapes onto coins. Publication in a PCGS Registry entry does not mean PCGS separately certified the owner’s doubling claim.
How to Identify
Use the collector’s shield description to focus on the upper lines and adjacent border. Preserve their spacing in the close-up.
Compare several related shapes under more than one light direction. A single bright edge can imitate another raised line without reflecting doubled design.
A scratch or flat shelf from striking movement is insufficient to establish this report. The source does not extend the pattern to doubled stars or other unmentioned front details.
What It’s Worth
Estimated range: $300–$1,000 for a circulated example with convincing shield doubling and sound attribution. Ordinary XF45 and AU53 sales at $336 and $512 provide condition comparisons.
The range is not a realized price for the displayed collector coin. Clear repeated detail and attractive original surfaces would strengthen the case for the upper estimate.
3. 1850 Half Dollar Earlier Strokes Survive on 5 and 0: Repunched Date Error
The Philadelphia references show more than one arrangement of date remnants. One XF45 has extra detail at the upper stroke of 5 and lower-right side of 0; a separate MS63 has an earlier 0 below and to the right.
Repeated date-punch applications left those pieces in the die. They represent earlier positions of the same year’s digits, not an older year underneath 1850.
How to Identify
Select one documented date pattern and compare the complete date before magnifying the remnant. Do not combine the XF45 positions and the MS63 position into one required arrangement.
The extra stroke should preserve a recognizable raised portion of a numeral. A cut or a flat ledge beside a digit has a different structure.
The ordinary open or closed form of 5 does not by itself establish repunching. Confirm the absence of O so the coin matches the Philadelphia examples.
What It’s Worth
Estimated range: $1,000–$6,000 from attractive circulated pieces to comparable unworn coins. A repunched-date NGC MS64 sold for $5,520 at Heritage in May 2025.
MS64 means the coin has no circulation wear and some surface marks. A worn half with the same sort of remnant cannot inherit that high-grade result without comparable preservation.
4. 1850 Half Dollar Another O Curve Remains at the Mintmark: Repunched Mintmark Error
At New Orleans, the O was punched separately into the reverse die. A slight change in position between blows could leave portions of an earlier O inside or beside the finished letter.
The extra curve should belong to a letter shape. A nearby crack, bump, or dent has to be distinguished from the earlier punch impression.
How to Identify
Examine both the opening and outside of O with a magnifier. Follow any extra curved segment rather than assuming a direction that the general report does not provide.
Compare the exact contour with an identified Repunched O example. Check for attached material, scratches, or impact damage that could create a false second edge.
Record 1850 and the surrounding reverse design along with the close-up. Clear mintmark evidence needs to remain connected to the complete half dollar.
What It’s Worth
Estimated range: $500–$1,500 for circulated examples with similarly clear extra detail. The GreatCollections Repunched O archive reports $1,186.88 in July 2026 for PCGS XF40.
XF40 denotes moderate wear. That identified transaction is more specific to this feature than ordinary New Orleans sales, while cleaning, heavy wear, or weak remnants can change the value.
5. 1850 Half Dollar Faint Shapes Lie Right of the Eagle’s Shield: Clashed Dies Error
The Philadelphia coin in the Maurice Storck auction has faint raised traces immediately right of the reverse shield. It also has a repunched date, though the two features have different causes.
Clashes begin when the dies touch without a blank between them. Parts of one design can mark the other die and later appear on coins as unwanted shapes.
How to Identify
Use the Storck catalog description and photographs for the actual Philadelphia example. Keep the shield visible so the traces’ position is unambiguous.
Try soft illumination followed by low side light to reveal the shallow marks. A scratch cuts into the surface, while a convincing clash should fit the transferred design evidence.
Do not identify the clash from the repunched date alone. One feature may help locate the reference coin without proving the cause of every other mark on it.
What It’s Worth
Estimated range: $2,500–$5,000 for an MS63 Philadelphia example comparable to the cataloged coin. MS63 is an unworn grade with noticeable marks.
The separate MS64 repunched-date half sold for $5,520 in May 2025 and offers a higher-grade comparison. It is not a supplied realized price for the Storck clash coin.
The estimate concerns the full coin and its surfaces. It does not create a fixed additional charge for the faint traces beside the shield.
Conclusion
Each location has its own question: did the elbow lose a fold, did the shield repeat, did a date or mintmark punch shift, or did the dies transfer a foreign shape? Start with the correct mint and inspect the relevant group of details.
The estimated $250–$6,000 span includes both reports and identified sales. Keep the $1,186.88 Repunched O result separate from the $5,520 Philadelphia date coin and the estimates for other features.
