1812 Half Dollar Error List with Pictures
One 1812 half dollar with cracks, clash marks, and a slightly off-center strike sold for $3,240 in March 2021. Its MS63 grade meant no circulation wear, though marks were visible.
These 1812 half dollar errors have estimated values of $150–$8,000. The highest range concerns a rare coin whose edge never received its normal lettering.
Read on to compare tilted designs, repeated impressions, raised lines, and that unusual plain edge.
1. 1812 Capped Bust Half Dollar Rotated-Die Error (Estimated Up to $700)
The eagle can finish tilted after you turn an upright Liberty over. Separate 1812 examples show back rotations of about 60 degrees clockwise and nearly 90 degrees clockwise.
The two dies, or steel stamping tools, were positioned at different angles to each other. The coin need not have an unusual shape or a shifted portrait.
The catalog names O-104 and O-104a identify particular tool pairs and stages of wear. A separate O-104 offering is graded NGC VF Details.
That listing gives no angle. The 60-degree and nearly 90-degree measurements therefore belong only to the examples that were actually measured.
Estimated Value
Estimate $150–$700 for a circulated Very Fine example with a clear, repeatable rotation. Surface problems generally favor the lower part of the range.
The NGC VF Details offering identifies the error and a condition problem, but provides no publicly visible completed price. The estimate is not that auction’s result.
An ordinary 1812 PCGS AU58 sold for $2,196 in February 2026. Its slight wear makes it much better preserved than the worn rotation comparison.
How to Identify
Set Liberty upright beside a fixed vertical line, then turn the coin from top to bottom without twisting it. A normally aligned United States coin finishes with the back upright.
Repeat the movement and photograph the result. Measure the eagle’s tilt from the fixed line, rather than comparing two separately straightened auction pictures.
Use a 10× magnifier around the lettered edge to look for a joining seam or alteration. A scale and calipers can compare a loose coin with 13.48 g and about 32.5 mm before wear.
Use recorded measurements for a sealed example. The direct test is the eagle ending at the same tilted angle after each controlled top-to-bottom turn.
2. 1812 Capped Bust Half Dollar Double-Struck Obverse Error (Estimated Up to $1,800)
A second impression can remain on the front even when the back is not described as doubled. Heritage identified that combination on an 1812 Large 8 half from the Merrill Collection.
The coin was certified PCGS VF30, indicating noticeable wear with much detail remaining. Its front was described as double struck.
Movement before the second blow can leave pieces of the first image beside the later one. Several repeated details should fit the same movement.
The catalog does not name a particular doubled letter or amount of shift. Large 8 simply describes the date style, not another error.
Estimated Value
The Merrill VF30 sold for $1,200 at Heritage in February 2018. Estimate $900–$1,800 for a similarly worn, certified example with recognizable repeated front details.
That historical result is a comparison, not a fixed present-day price. Clear separation and appealing surfaces support the higher end.
A faint doubled-looking edge without other matching details is less convincing. Cleaning or a poorly defined second impression also makes the VF30 sale less useful as a direct comparison.
How to Identify
Begin with the whole front and mark each possible repeated detail in a photograph. The pieces should fit one second image, rather than a collection of unrelated nicks.
Use a 10× magnifier to compare their raised shapes. Flat shelves beside a single design edge, scratches, and changing reflections can imitate doubling.
Examine the back too, while remembering that this documented error was identified on the front. Confirm 1812, the Large 8 style, and the lettered edge.
A scale and calipers can compare a loose half with 13.48 g and roughly 32.5 mm. The strongest quick clue is several displaced front details matching the certified example’s second impression.
3. 1812 Capped Bust Half Dollar Die-Crack Error (Estimated Up to $3,800)
A raised line can run from the end of Liberty’s bust toward the first two stars. This is a known feature of the later tool stage called O-105a.
The steel stamping tool cracked during use. Silver entered the opening on later strikes and formed a ridge on the coins.
As the crack grew, the ridge could become longer or more obvious. It is raised metal rather than a cut made into a finished coin.
The same coin may also show clash marks, but they have another cause. A crack follows broken steel instead of copying part of the opposite design.
Estimated Value
The O-105a graded PCGS MS63 sold for $3,240 in March 2021. Estimate $150–$3,800 from ordinary circulated coins through a similarly preserved MS63 example.
The sale coin also had clash traces and slight off-centering. Its price cannot be divided into separate charges for each feature or counted repeatedly.
Most of the wide range reflects wear, marks, and overall appearance. A clear bust-to-stars crack may interest specialists, but does not give a worn coin the value of an unworn one.
How to Identify
Follow the line from the bust tip toward stars one and two with a 10× magnifier. Move the light to opposite sides to confirm that the line stands above the silver.
A scratch cuts downward and may leave rough edges or dragged metal. Normal hair or clothing details should not be joined into an imagined crack.
Compare full photographs of both faces with an O-105a example, keeping the border visible for orientation. Inspect the lettered edge as well.
A scale and calipers can check a loose coin against roughly 13.48 g and 32.5 mm. The quickest useful distinction is the raised, continuous route from bust to stars rather than a cut below the surface.
4. 1812 Capped Bust Half Dollar Die-Clash Error (Estimated Up to $3,800)
Faint extra shapes appear below the scroll on the back, especially toward its right side. On O-105a, these are recorded as clash marks.
The stamping tools hit each other without a blank between them. They picked up parts of the opposite design, which later coins then copied.
The MS63 example sold in 2021 shows several sets of these marks. Repeated contact can make the pattern harder to follow.
A familiar-looking line still needs a real connection to the other face. A scratch or a crack through the tool does not become a clash simply because it lies below the scroll.
Estimated Value
Estimate $200–$3,800 from circulated O-105a coins with recognizable clashes through examples comparable to MS63. The March 2021 sale at $3,240 describes several clash sets.
It is the same coin already discussed for its cracks, not another independent error sale. The amount prices all its features and condition together.
Stronger transferred detail can appeal to specialists. Wear and surface quality still explain much of the difference between a modest circulated example and the top of the range.
How to Identify
Hold the back so the scroll is horizontal. Examine beneath it and to the right with a 10× magnifier and light from the side.
Compare the extra contour with Liberty’s design on the opposite face. Its position must fit the way the tools faced each other, rather than merely resemble a line of similar length.
Photograph the whole back before taking the close-up. Check the dated front and lettered edge, then use a scale and calipers against about 13.48 g and 32.5 mm for a loose example.
Recorded measurements are enough for a sealed coin. Begin with the recognizable fragment of Liberty’s opposite-side design beneath the scroll, rather than any unexplained mark there.
5. 1812 Capped Bust Half Dollar Off-Center Strike Error (Estimated Up to $4,000)
An off-center half may keep its date and most of its design while sitting unevenly on the blank. Two recorded 1812 coins show why the shift and the condition need separate attention.
Heritage lists a Large 8 O-103 graded ANACS F15 as struck off center. F15 describes noticeable circulation wear.
Stack’s Bowers calls the much better-preserved O-105a MS63 only slightly off center. Neither description provides a measured percentage.
These are different coins. Early half dollars often have uneven borders from normal manufacture, so a narrow rim in one photograph does not establish the amount of an off-center strike.
Estimated Value
The ANACS F15 O-103 sold for $780 at Heritage on July 29, 2020. The separate MS63 O-105a brought $3,240 in March 2021.
Estimate $600–$4,000 for examples comparable to those circulated and unworn coins. The range does not price a hypothetical dramatic shift.
A large blank crescent or a different condition would need a closer comparison. Remember that the MS63 price also includes its cracks and clash marks.
How to Identify
Show the full outline on both faces and identify where the design approaches one edge. Keep the coin’s position clear as you turn it over to compare the other side.
Both designs should support the same displaced blank. A centered back with only the front shifted may involve a misaligned stamping tool instead.
Use a 10× magnifier around the edge to look for filing or compression. Calipers record the outline against roughly 32.5 mm, while a scale checks against the original 13.48 g.
Normal examples have edge lettering. The direct starting point is matching displacement on both faces, rather than a percentage guessed from one narrow border or a tightly cropped picture.
6. 1812 Capped Bust Half Dollar Missing Edge Lettering and Expanded Strike (Estimated Up to $8,000)
No words appear around the edge of this unusual O-103. Henry Hilgard’s published examination describes it as completely plain, and the dealer lists the coin as NGC AU58, with slight wear.
The blank apparently skipped the edge-lettering machine before its faces were struck. That machine normally added words while compressing the blank’s circumference.
Skipping the step explains the wider margins around stars and back lettering. The silver began the strike without the usual edge preparation.
The writer described a broadstruck appearance. This early production problem differs from the failed restraining ring that causes a broadstrike on a modern coin.
Estimated Value
For an authenticated lightly worn coin with both the plain edge and expanded form, estimate $3,000–$8,000. The dealer marks the O-103 sold but does not publish its selling price.
An ordinary 1812 PCGS AU58 brought $2,196 in February 2026. It provides a comparison for slight wear, not the omitted edge lettering.
The higher allowance estimates collector interest in that unusual skipped step. It is not a documented auction result for the plain-edge coin.
How to Identify
Photograph a complete turn around the edge, not just one smooth patch. A 10× magnifier can reveal faint remaining letters, filing lines, or compressed metal from later alteration.
The published examination describes a rounded transition at the front edge and a sharper one at the back. Those different profiles support the skipped lettering step.
Use calipers to record the actual width, comparing with the usual roughly 32.5 mm without assigning that diameter to this wider example. A scale checks against the original 13.48 g.
The strongest combination is a completely plain edge with original surface texture, matching edge profiles, and the wider margins visible on both faces.
Conclusion
Estimated values for these 1812 halves range from $150 to $8,000. The MS63 sale shows that cracks, clashes, and slight off-centering can share one coin and one price.
The plain-edge example points to an earlier skipped step in preparing the blank. Match each feature to its own specimen, using a controlled turn for rotation, raised lines for cracks, and a full edge view for missing lettering.
