1827 Dime Error List with Pictures
An unusual 1827 dime graded PCGS Specimen-65 sold for $40,800 in August 2019. Its rare production type and condition explain that price, rather than its thin raised crack alone.
These 1827 dime errors also include a repeated 7 and a backward eagle on an undated coin assigned to this year. Estimated whole-coin values span $100–$60,000.
Read on to check the details that separate these very different examples.
1. 1827 Capped Bust Dime Repunched Final 7 (Estimated Up to $2,000)
The final 7 has part of another 7 beside it. Collectors once called this 1827/5, but the extra shape is now understood as the same numeral punched again.
The date punch entered a die, the steel tool that stamps coins, in a slightly different position. Some of the first 7 remained.
Coins made with that tool can repeat the extra outline. They did not need a second strike to create it.
This variety is called JR-1. Compare the raised shape with a 7 instead of trying to make it fit the older 5 nickname.
Estimated Value
Estimate $100–$2,000 for worn JR-1 dimes with readable repunching. Original surfaces and remaining detail affect the whole-coin value.
PCGS records an exceptional MS66 at $15,525 in October 2000. That grade describes an unworn coin with few marks, in a different price group from worn examples.
The older 1827/5 name does not describe another rarity. It should not add an extra premium to the same repeated-7 variety.
How to Identify
Use a magnifier on the entire final 7, with a clear JR-1 photograph beside it. Follow the extra outline rather than judging one damaged corner.
The remnant should fit another placement of a 7. A scratch or nearby date stroke does not prove an underlying 5.
Keep the full date and portrait in another photograph. Those details help confirm the variety instead of relying on a tiny cropped image.
A scale and calipers can check about 2.70 grams and 19 mm, allowing for wear. The dime is roughly 89.2% silver and has edge grooves.
For the quickest match, trace a raised second 7 beside the final numeral in the same position as the reference.
2. 1827 Capped Bust Dime Reverse-Design Brockage Attributed to 1827 (Estimated Up to $10,000)

One face has a normal eagle, while the other has a backward eagle pressed down into the silver. Collectors call the sunken copy a brockage.
A previously struck coin pressed its raised design into this one during striking. The normal dated face did not form, so no visible date proves 1827.
The assignment comes from matching cracks on the eagle side. The same tool served in 1824 and 1825, but the stronger cracks support its later 1827 use.
That comparison belongs to this specimen. It does not date every similar-looking eagle brockage.
Estimated Value
Estimate $2,000–$10,000 for an authenticated brockage with this documented year assignment and clear surviving detail. No sale price is claimed for the undated specimen.
A related 1828 dime with a reverse brockage sold for $5,750 in February 2009. NGC graded it AG3, meaning very heavy wear.
That coin has a different transferred design and receiving face. Its sale offers a broad error comparison, not proof of the undated coin’s year or exact value.
How to Identify
Start with the normal eagle face and compare its details and cracks with the identified reference. Then inspect the backward image through a magnifier.
The copied design should sink into the surface. Fresh pressure marks, crushed rims, or a seam can reveal later squeezing or joined pieces.
The collection description explains how the stronger cracks support 1827 after the tool’s earlier uses. Keep the label “undated, attributed to 1827” with the coin.
Use a scale and calipers against about 2.70 grams and 19 mm. Its original alloy is roughly 89.2% silver, with edge grooves.
The key year check is the matching later crack pattern on the normal eagle side, not the backward eagle alone.
3. 1827 Capped Bust Dime JR-10 Specimen Reverse Die Crack (Estimated Up to $60,000)
A fine raised line starts at F in OF and passes through the S of PLURIBUS. It crosses the eagle’s head and ends near the upper right wing, below the beak.
Metal filled a crack in the stamping tool during striking. The resulting ridge follows the tool’s damage.
This JR-10 coin is graded Specimen-65, a special production category rather than an ordinary circulation issue. That distinction is central to its value.
The catalog suggests that reworking and reheating the tools caused stress. That proposed cause is separate from the raised line you can actually see.
Estimated Value
The PCGS Specimen-65 JR-10 sold for $40,800 in August 2019. Estimate $20,000–$60,000 for comparable examples in this exceptional category.
The whole-coin price reflects rare production, variety, and preservation. It is not a $40,800 bonus for a thin crack.
An ordinary 1827 dime with a raised line needs a different comparison. The crack alone cannot give it the specimen classification or the auction coin’s value.
How to Identify
Follow the full route under a magnifier: F, then the S of PLURIBUS, across the head, and toward the right wing. Photograph the whole line together.
An isolated scratch near one endpoint is not a match. Use side lighting to check that the line rises above the surface.
Confirm JR-10 and its specimen classification through the complete coin and grading record. A surface photograph cannot prove the catalog’s suggested reheating history.
A scale and calipers can compare the coin with about 2.70 grams and 19 mm. Inspect its grooved edge against the specimen reference; the alloy is roughly 89.2% silver.
Begin with the complete raised route from F toward the wing, then verify the rare coin’s classification separately.
Conclusion
Check the second 7, the backward eagle, or the raised F-to-wing line according to the coin in front of you. These features need different comparisons.
Estimated whole-coin values run from $100 to $60,000. Keep the undated brockage’s assigned year and the JR-10 specimen classification in the description, because neither can be established by an unusual mark alone.
