The 2018-S Sacagawea Native American Dollar is worth anywhere from $5 in standard proof condition to over $1,500 for pristine high-grade specimens. While these golden-colored coins are often found in change, the special “S” mint mark version from 2018 holds a unique place in the hearts of modern collectors and investors alike.
| Coin Condition/Grade | Estimated Market Value |
|---|---|
| Deep Cameo Proof (PR65) | $5.00 – $12.00 |
| Deep Cameo Proof (PR69) | $15.00 – $25.00 |
| Perfect Proof (PR70) | $80.00 – $150.00+ |
| Enhanced Uncirculated (From Set) | $10.00 – $45.00 |
Identifying Your 2018-S Native American Dollar
If you have stumbled upon a golden dollar featuring the iconic image of Sacagawea, your first step is to check the edge of the coin. Since 2009, the Native American Dollar series has utilized “edge-incused” inscriptions, meaning the date and mint mark are stamped into the side of the coin rather than the face. If you see a small “S” on the edge, you have a coin minted in San Francisco. Because these were never intended for general circulation, they are much rarer than the “P” or “D” versions you might get as change from a vending machine.
To get an instant identification of your find, many hobbyists use a top coin identifier app to confirm the specific variety and minting details. The 2018 reverse design is particularly striking, featuring a portrait of Jim Thorpe, the legendary athlete, with the inscriptions “JIM THORPE” and “WA-THO-HUK” (his native name). Understanding these design elements is crucial because the “S” mint mark was only available in specific collector sets issued by the U.S. Mint, making it a “NIFC” (Not Intended For Circulation) issue.
If you are unsure about the subtle differences between proof finishes and standard uncirculated strikes, the CoinKnow app can help you verify the surface texture using your phone’s camera. This is helpful because the 2018-S was produced in two distinct finishes: the traditional mirror-like Proof and the matte-like Enhanced Uncirculated finish found in the Native American Coin and Currency Set.

The Significance of the 2018 Jim Thorpe Reverse
The 2018 entry in the Native American Dollar series honors the contributions of Jim Thorpe, a member of the Sac and Fox Nation. Thorpe is widely considered one of the greatest athletes in modern history, having won Olympic gold medals in the decathlon and pentathlon in 1912, while also excelling in professional football and baseball. The “WA” in our title refers to “Wa-Tho-Huk,” which translates to “Bright Path”—a fitting name for a man who blazed a trail for Indigenous athletes in the United States and across the globe.

Because the reverse design changes every year, certain years become more popular based on the historical figure depicted. The Jim Thorpe design is a favorite among sports memorabilia collectors as well as numismatists. When researching the 2018 Sacagawea dollar value, you will notice that the historical significance often drives demand during auctions. Collectors are willing to pay a premium for “perfect” specimens that honor this American icon with no scratches or “bag marks.”
When evaluating these coins, keep in mind that the condition is everything. A 2018-S coin that has been touched by bare fingers or kept in a pocket will lose its “Proof” luster rapidly. Using the CoinKnow app, you can compare the luster of your coin against high-resolution images of gallery-grade pieces to see where your coin falls on the grading scale.

Technical Specifications and Mintage Figures
Knowing the “stats” of your coin can help you spot fakes and understand its rarity. The 2018-S Proof Dollar is composed of a pure copper core with an outer layer of manganese brass, which gives it that distinct “gold” look. Interestingly, the San Francisco mint produced a relatively small number of these compared to the millions of “P” and “D” coins minted in Philadelphia and Denver for the general public and collector bags.
| Specification | Details |
|---|---|
| Composition | 88.5% Copper, 6% Zinc, 3.5% Manganese, 2% Nickel |
| Weight | 8.10 grams |
| Diameter | 26.5 mm |
| 2018-S Proof Mintage | Approx. 917,000 |
The mintage for the 2018-S Proof is actually quite low by modern standards, sitting under one million units. This scarcity ensures that even lower-grade proofs maintain a value above their face amount. If you are tracking the current price for 2018 dollar coins, you’ll see that the “S” mint mark consistently outperforms the “P” and “D” versions found in circulation.

Grading and the Value of PR70 Deep Cameo
In the world of coin collecting, “grading” is the process of determining a coin’s physical condition on a scale of 1 to 70. For proof coins like the 2018-S, the goal is to achieve a grade of PR70 (Proof 70), which indicates a perfect coin under 5x magnification. Additionally, collectors look for the “Deep Cameo” (DCAM) designation, which means there is a heavy frost on the design elements and a mirror-like finish in the background fields.
A 2018-S Proof Dollar graded as PR70 Deep Cameo by a service like PCGS or NGC can sell for $100 to over $200. However, if that same coin has even one microscopic scratch, it might drop to a PR69, where the value falls to roughly $15. This “grade gap” is why it is so important to handle these coins only by their edges and keep them in protective capsules.
If you are unsure whether your coin is worth the cost of professional grading (which can be $30-$50 per coin), use the CoinKnow tool to get a preliminary assessment. The app helps you identify if there are any surface imperfections that would prevent the coin from reaching that elusive “Perfect 70” status.
Wait, I Found a 2018 Dollar With No “S”!
It is very common for people to find 2018 dollars without the “S” mint mark. These are usually the 2018-P (Philadelphia) or 2018-D (Denver) versions. While these were not released into general circulation for spending, they were sold in 25-coin rolls and 100-coin bags by the Mint. Many of them eventually end up in pocket change when collectors break open rolls or when someone spends a collection.

While the “S” Proof is the most coveted for its beauty, the “P” and “D” mintages are still worth more than $1 to a collector if they are in Uncirculated (MS) condition. A 2018-P in MS67 condition can still fetch a respectable price. However, most 2018 dollars found in change will be considered “circulated” and are generally worth only their face value of $1, unless they happen to be the rare 2018-S Proof that someone accidentally spent!
| Mint Mark | Strike Type | Typical Value |
|---|---|---|
| P (Philadelphia) | Business Strike | $1.25 – $3.00 |
| D (Denver) | Business Strike | $1.25 – $3.00 |
| S (San Francisco) | Proof | $5.00 – $150.00 |
FAQ
Q: Why is the date on the edge of the 2018 dollar?
A: In 2009, the U.S. Mint moved the date, mint mark, and the motto “E Pluribus Unum” to the edge of the Native American Dollar to allow for a larger, more detailed design on the obverse and reverse faces of the coin.
Q: Is the 2018-S dollar made of real gold?
A: No, the coin does not contain any gold. It is made of a manganese-brass alloy over a copper core. The manganese gives it the golden color, but it will tarnish to a dull brown over time if exposed to air and oils.

Q: How can I tell if my 2018-S is an “Enhanced” version?
A: The “Enhanced Uncirculated” version was only sold in the 2018 Native American Coin and Currency Set. It features a unique finish where different parts of the design have different levels of frosting and polishing, giving it a more three-dimensional look compared to a standard proof.
Q: Can I spend my 2018-S dollar at the store?
A: Yes, it is legal tender for one dollar. However, doing so is not recommended, as the coin is worth at least 5 to 10 times its face value to a collector, even in used condition.
Q: Where is the best place to sell my 2018-S coin?
A: For high-grade certified coins (PR69 or PR70), reputable auction sites or specialized coin dealers are best. For uncertified coins, local coin shops or online marketplaces like eBay are popular options for reaching hobbyists.
