1850 Dime Error List with Pictures
An exceptionally preserved 1850-O dime sold for $40,800 in August 2022, graded MS67. That means unworn with very few marks; the sale did not establish a rotation error.
For the conditions discussed in this 1850 dime error list, estimated values run from $30 to $6,500. Features include raised cracks, fine doubled details, and a back tilted about 45 degrees.
Use the checks below to separate an extra line in the design from a mismatch between the two sides.
1. 1850 Liberty Seated Dime Die Cracks (Estimated Up to $2,000)
A crack through the wreath can look like an extra stem until it enters the lettering or rim. Several Philadelphia stamping tools developed cracks that left raised lines on 1850 dimes.
These tools are called dies. Silver entered their narrow openings during striking, making ridges on the finished coins.
One recorded back has crossing lines from the upper wreath toward STATES. A stronger crack passes through the lower left wreath and stem to the border.
Other examples have lines near the date or front stars. They share the same general cause, but their routes belong to separate examples.
Estimated Value
The estimated whole-coin range is $30–$2,000, from worn examples to attractive unworn coins. A clear, continuous crack is easier to appreciate than one mostly lost through wear.
Greysheet lists $120 for a PCGS EF45 in November 2024 and $660 for a PCGS MS63 in September 2025. EF45 has noticeable wear; MS63 is unworn with marks.
These are ordinary 1850 condition comparisons. Neither amount is assigned to the specific pictured crack pattern.
How to Identify
Follow a suspected extra stem with a 10× magnifier until it leaves the wreath. On the recorded back, the lower-left route continues through the stem to the rim.
Check the crossing cracks above the wreath as another point of comparison. Keep the complete back visible so the routes stay in context.
Move the light across the line from several directions. A raised ridge differs from a scratch cut into the silver, even when shadows look similar in one photograph.
When safely accessible, compare a scale reading with 2.67 g and use calipers against 17.90 mm. Inspect the edge grooves for filing or squeezing.
Look for a continuous raised line crossing the normal design, with no gouged channel beneath it.
2. 1850 Liberty Seated Dime Doubled Die (Estimated Up to $5,500)
Extra outlines beside shield stripes can be easy to miss. On the recorded front, they lie left of odd-numbered stripes in the lower shield, including the first and third.
A separate back variety has light doubling in the wreath, parts of AMERICA, and the left ribbon end. These extra contours were already present in the stamping tools.
The coin did not need a second blow to receive them. Each normal strike could copy the same doubled details.
Fine lines behind the back lettering are separate marks. They should not be counted as more doubled letters just because they appear nearby.
Estimated Value
The estimated whole-coin range is $50–$5,500, from worn examples with readable doubling to very well-preserved unworn coins. Fine details survive best on original surfaces.
Greysheet’s sales index lists $4,800 for a PCGS MS65+ CAC F-101 in June 2024. That high-grade coin is a different variety.
It provides a same-year quality comparison, not a sale of the F-106 front doubling or F-110 back doubling. Their small outlines must be identified separately.
How to Identify
First check that the coin is Philadelphia, with no O mint letter. An accessible dime can be checked with a scale and calipers against 2.67 g and 17.90 mm.
Inspect the edge grooves and general surface for alteration. Correct measurements alone cannot confirm tiny doubled details.
Use a 10× magnifier on the lower shield and compare the stripes with a normal example. For the separate back variety, examine the wreath, AM in AMERICA, and the left edge of the left ribbon tail.
A flat shelf caused by movement during striking is different from a rounded extra contour. Compare the precise doubled shield lines or back outlines with the matching variety picture, rather than treating nearby scratches as part of the feature.
3. 1850-O Liberty Seated Dime Rotated Reverse (Estimated Up to $6,500)
The Large O identifies New Orleans, but the O itself is not out of place. The unusual feature is the angle between the front and back designs.
The 1850-O catalog describes F-105a with its back turned about 45 degrees left. One stamping tool worked outside its intended rotational position.
Both designs can otherwise remain complete and centered. The error becomes clear when the coin is turned over in a controlled way.
Separately straightened photographs can hide this relationship. Seeing two upright pictures in a listing does not show how the actual coin lines up.
Estimated Value
The estimated whole-coin range is $150–$6,500, from worn examples to attractive lightly worn or lower unworn coins. The New Orleans issue and condition contribute substantially.
A reported $399.99 seller offering concerns an ungraded F-105a. It is an asking price, not a completed sale.
PCGS records the $40,800 MS67 result for an exceptional 1850-O. That sale was not identified as a rotation error and should not be used as its specific price.
How to Identify
Secure the coin in a transparent holder with Liberty upright. Turn it from top to bottom without letting it spin inside the holder.
Normal alignment leaves the back upright. The recorded F-105a should instead lean about 45 degrees left.
Repeat the turn against the same vertical guide and record both positions. A sideways flip or a loose coin can create a misleading angle.
Inspect the Large O with a 10× magnifier and check the edge grooves for a seam. Use a scale and calipers when safely accessible against 2.67 g and 17.90 mm.
The important result is the same leftward lean after each controlled top-to-bottom turn. The angle of a cropped photograph is not enough to establish it.
Conclusion
Estimated values for the 1850 errors discussed here run from $30 to $6,500. The exceptional $40,800 New Orleans sale is a separate high-grade comparison, without an established rotation.
Follow raised cracks beyond the wreath, inspect the shield or ribbon for repeated outlines, and turn a Large O coin carefully to test alignment. Each check answers a different question.
Condition and original surfaces remain part of every price comparison.
