Rare 1808 Half Dollar Errors (List & Pictures)
Two coins account for several of the features discussed here: a worn dealer-offered 1808 and an unworn 1808/7 that brought $2,300 at auction in 2002. Their individual marks do not have separate sale prices.
Estimated whole-coin values for 1808 half dollar errors run from $150 to $4,000. Examine the outline and design positions first, then distinguish repeated contours, raised fractures, and traces transferred from the opposite face.
| Visible feature | Category | Estimated whole-coin value |
|---|---|---|
| Unusual spreading | Reported broadstrike | $900–$2,500 |
| Unequal borders on both faces | Slight off-center strike | $250–$4,000 |
| Reverse tilt | Reported rotation | $200–$800 |
| Related remnants of another impression | Reported double strike | $900–$3,000 |
| Second neck contour | Reported double profile | $200–$600 |
| Raised lines or a local lump | Die cracks and breaks | $150–$1,500 |
| Traces of the opposite design | Clashed dies | $200–$4,000 |
These Philadelphia halves have no mint letter and have words on the edge. Their original standard weight is 13.48 grams, with a diameter around 32.5 millimeters; wear and early manufacturing variation affect comparisons.
1. 1808 Half Dollar An unusually spread outline: Reported Broadstrike Error
Start by considering the entire outline of the dealer-described 1808 O-106. The seller calls this PCGS VG10 coin both broadstruck and double struck, so another blow may be relevant to its expanded shape.
Early Capped Bust halves were made with an open collar, a guide that did not tightly confine the blank like a modern collar. Explaining this coin simply as a modern collar failure would miss that difference.
How to Identify
Compare width in several directions and thickness at several points with an ordinary half dollar of the same early type. One wide border is less useful than measurements showing how the whole coin spread.
Inspect the edge lettering and nearby designs for stretching that fits the striking process. Flattening from later hammering needs to be separated from original expansion.
VG10 indicates substantial circulation wear. The numerical PCGS grade does not, by itself, show that PCGS certified either error named by the dealer.
What It’s Worth
An estimated $900–$2,500 covers similarly worn coins with convincing expansion and second-strike evidence. The combined-error O-106 carries a $1,900 asking price, not a completed sale result.
That one offer also appears in the double-strike discussion. Adding the two estimates would count the same specimen twice.
2. 1808 Half Dollar The design sits nearer one edge: Slight Off-Center Strike Error
Uneven borders can provide a quieter clue than obvious missing metal. Heritage described an NGC MS62 1808/7 as slightly off center, without assigning a direction or percentage.
The 1808/7 is an overdate, with remains of a 7 beneath the final 8. Its shifted design, cracks, and clash marks all belong to one auction coin.
How to Identify
Use full photographs to compare the border and design center on both faces. A displaced blank should produce a compatible relationship, whereas a single uneven face may involve one misaligned die.
Inspect the small border teeth for original incomplete striking rather than scraping or wear. The recorded description supports a modest shift and does not justify inventing a dramatic missing portion.
What It’s Worth
Estimated values are $250–$1,000 for worn coins with a modest shift and $2,000–$4,000 for a similarly preserved unworn overdate. Most of the difference concerns the underlying coin and its condition.
The NGC MS62 1808/7 sold for $2,300 on June 8, 2002. This historical result purchased all its features together, including the clashing discussed later.
3. 1808 Half Dollar A leaning eagle after a controlled flip: Reported Rotated Reverse Error
A rotation changes the relationship between the two faces without necessarily moving either design away from the center. It results when the dies are turned relative to their intended alignment.
A collector measured about 22 degrees on examples identified as O-109 and O-109a. The account gives conflicting direction words, so only the approximate angle can be retained confidently.
How to Identify
Hold the portrait upright against a vertical reference, then flip top to bottom without twisting sideways. Repeat to see whether the eagle returns to the same tilted position.
Prevent the coin from slipping in its holder and use an alignment guide to measure the angle. Two photographs independently turned upright cannot preserve the relationship being tested.
What It’s Worth
An estimated $200–$800 applies to worn examples with a confirmed rotation around the reported 22 degrees. The collector’s measurement is an observation, not a traced sale.
A 2000-P Kennedy half with a much larger 75-degree rotation sold for $79 in March 2025. That different-era PCGS MS61 coin illustrates why angle alone cannot price an early silver half dollar.
4. 1808 Half Dollar Parts of the design occupy a second position: Dealer-Reported Double Strike Error
Instead of concentrating on one extra line, look for design remnants that fit together. If a struck coin received another blow after moving, surviving parts of its first impression may share a second recognizable position.
The dealer calls the worn O-106 a double strike but does not provide an exact direction or diagnostic location. That claim should not become an invented description of two complete portraits or dates.
How to Identify
Trace possible remnants among the stars, portrait, letters, and border teeth. Several details that fit one shifted impression offer stronger support than isolated doubled-looking edges.
Include the reverse and edge in the examination so any distortion belongs to the same physical sequence. Flat shelves, impact dents, and wear can obscure or imitate short marks.
What It’s Worth
An estimated $900–$3,000 covers worn examples with a demonstrable extra impression. The PCGS VG10 O-106 listing asks $1,900 for the same coin described as expanded in the first section.
A clear surviving repeat can attract more interest than an uncertain remnant. Keep the seller’s error wording separate from the certified numerical grade and from a completed transaction.
5. 1808 Half Dollar A fine second line at Liberty’s neck: Reported Double Profile Error
A thin extra contour at the neck is a narrower observation than a second strike. An owner reported this appearance on an 1808 identified as O-105 and relayed a specialist’s response in a collector discussion.
O-105 identifies a catalog variety; it does not establish the cause of the outline. Movement during striking, pressure damage, reflections, and photographic blur all need consideration.
How to Identify
Examine where the neck meets the surrounding flat surface with magnification and changing light. Determine whether the feature is raised contour, a flat shelf, or a damaged edge.
Compare two sharply focused photographs and check other design areas for related repetition. A persistent neck line confirms its physical appearance but does not prove a doubled obverse die.
What It’s Worth
A worn example with a modest clear second contour has an estimated whole-coin range of $200–$600. The surviving detail and surface condition account for much of that amount.
No completed double-profile sale is supplied. The $1,900 combined-error O-106 offer concerns another coin and cannot be transferred to this small neck feature.
6. 1808 Half Dollar Raised paths and a local lump: Die Cracks and Die Breaks Error
A fracture in a die lets silver enter an extra opening, leaving a raised line on the coin. A larger missing portion of the tool can leave a more substantial raised patch.
The recorded 1808/7 has crack routes near the bottom of the date, beside the left stars, and across the tops of ATES. A different, normal-date 1808 has a larger break running from the left wing toward the tail feathers.
How to Identify
Follow each raised route continuously under low-angle light and compare it with the appropriate example. The collector record for the overdate supports its date, star, and ATES locations.
Do not combine the normal-date wing-to-tail break with the overdate’s crack map. A scratch cuts into the surface, while impact damage or corrosion can create a lump without recording a broken die.
What It’s Worth
Estimated worn-coin values span $150–$1,500, covering modest fractures through clear local breaks. Cleaning and damaged surfaces can weaken an otherwise useful comparison.
An 1826 O-104 with cracks on both faces sold through Early Cents for $1,020 including fees in August 2025. Its PCGS AU58 grade describes an almost unworn coin, and this different-year result is not a sale of either 1808 described above.
7. 1808 Half Dollar Faint traces of the opposite face: Clashed Dies Error
Some unexpected shapes originate before the coin enters the press. When the dies meet without a blank between them, contact can mark their surfaces and later transfer traces to coins.
Light clashing is reported on both faces of a collector’s 1808/7, and the separate NGC MS62 auction overdate also carries clash marks. The supplied accounts do not map every trace to a specific location.
How to Identify
Compare the suspicious shape with parts of the opposite design, using a mirrored photograph if helpful. The important connection is to the other face, rather than merely to an unfamiliar line.
Use several light angles to separate transferred shapes from recessed scratches and raised fracture lines. The previously described date and ATES routes identify cracks and should not be reused as clash diagnostics.
What It’s Worth
Estimated whole-coin values are $200–$900 for worn pieces with light clashing and $2,000–$4,000 for a comparable unworn overdate. These ranges reflect preservation and the underlying variety as well as the visible traces.
The $2,300 June 2002 auction result belongs to the same MS62 coin described under off-centering. Neither the clash nor the slight shift has a separate recorded purchase price.
Conclusion
Keep an outline question separate from a surface question: expansion, displaced designs, and rotation require different comparisons from a neck contour or a die crack. Matching a feature also means matching the correct coin’s documented locations.
The worn O-106 dealer offering and the unworn 1808/7 auction specimen each combine several features. Their prices describe complete coins, while the reported profile and rotation still need their own evidence.
