2018 Sacagawea Dollar Error List with Pictures
Jim Thorpe’s portrait and sports figures identify the 2018 dollar even when an unusual edge draws your attention. The two reported error types below concern the lettering step and the metal disc itself.
Their conditional estimates span $30–$10,000. For scale, a different-year 2002-D dollar on a quarter blank sold for $8,050 in January 2009.
This guide to 2018 Sacagawea dollar errors explains what to inspect before applying such comparisons. Start with the correct Jim Thorpe design, then follow the evidence on the actual coin.
2018 Sacagawea Dollar Reported Missing Edge Lettering
A completely plain edge is unusual on the Jim Thorpe dollar because its year and mint letter normally appear there. The expected edge also carries E PLURIBUS UNUM.
On ordinary dollars, this inscription is pressed into the edge after the faces are struck. A coin that misses that separate step can leave the Mint without those letters.
The 2018 error is reported in a year-specific list without an identified mint or authenticated specimen. Each candidate needs examination.
Faint surviving letters and letters facing the opposite direction are different observations. Neither is the same as an entirely missing inscription.
Estimated Value
For an authenticated Jim Thorpe missing-edge example, estimate $30–$500. Original surfaces, clear design details, and complete absence of the inscription would support a stronger price.
A 2007 Madison dollar graded NGC MS67 with missing edge lettering sold for $119 at Heritage in July 2025. That is a different-year Presidential dollar comparison.
The estimate does not apply to an edge smoothed by wear or tools. Such damage can reduce the ordinary coin’s value instead.
How to Identify
Use a normal Jim Thorpe dollar to establish how the edge letters should look, then examine the suspect coin beside it. Rotate both coins slowly so a shallow inscription cannot hide in shadow.
Record every surviving character. One faint letter means the edge is not completely unlettered, even if most of the circumference looks smooth.
Look at both rim transitions for filing, polishing, or a coating that fills the lettering. A loose coin should remain close to the normal 26.49 mm diameter unless another condition explains its size.
The Jim Thorpe design identifies the issue, while the missing mint letter leaves P or D unresolved. An original, fully unlettered circumference is the essential feature for a specialist to confirm.
2018 Sacagawea Dollar Reported Wrong Blank
A dollar made from the wrong metal disc may have an unusual size, weight, or color. The disc is called a blank or planchet before it receives a coin design.
A blank intended for another denomination can enter the dollar press and receive the dollar’s images. A smaller disc may lose outer details because the design extends beyond its edge.
The 2018 report does not identify which blank was involved. It cannot establish a quarter, nickel, or other substitute.
Coatings and chemical damage can also change appearance. A different color alone does not prove that the Mint used another blank.
Estimated Value
Estimate $1,000–$10,000 for an authenticated 2018 wrong-blank example, depending on the identified metal and the surviving design. The particular blank and surface condition would guide a closer comparison.
A 2002-D Sacagawea dollar on a quarter blank, graded NGC MS66, brought $8,050 at Heritage in January 2009. It is an older different-year example.
A published specialist listing records that coin’s history. Its quarter-blank identity and grade must not be assigned to an unexamined 2018 candidate.
How to Identify
The Mint gives a normal Jim Thorpe dollar a weight of 8.10 grams and diameter of 26.49 mm. Weigh a loose candidate accurately and measure across several directions before proposing another denomination.
Examine the edge for its metal layers and any filing, coating, or corrosion. Compare naturally incomplete design details with places where someone might have removed finished metal.
Both sides should belong to the 2018 issue. Keep Jim Thorpe’s artwork and Sacagawea’s portrait visible in the same set of photographs.
The normal dollar contains no gold despite its color. Professional metal testing, combined with the measured size and original struck edges, is needed to identify a genuine alternative blank.
Conclusion
These two reported 2018 errors need different evidence: an original unlettered edge for one, and an identified alternative metal blank for the other. Neither can be established by an unusual photograph alone.
The conditional estimated range is $30–$10,000. Use the Jim Thorpe design, complete edge views, and measurements where relevant to choose the right comparison.
Avoid cleaning or filing the coin, since its untouched surface helps explain what happened.
