2018-S Sacagawea Dollar Value: What Is This Proof Coin Worth?

The 2018-S Sacagawea Dollar is worth anywhere from $5 in standard proof condition to over $100 in perfect deep cameo state. While these golden-colored coins look like treasure, most found in everyday collections are modern “Proof” coins minted specifically for collectors rather than for general circulation at the grocery store.

Condition / Grade	Estimated Value
PR65 Proof (Standard)	$5.00 – $8.00
PR69 Deep Cameo	$15.00 – $25.00
PR70 Deep Cameo (Perfect)	$65.00 – $120.00

Identifying Your 2018-S Sacagawea Dollar Coin

If you’ve recently inherited a coin collection or found a shiny gold-toned dollar in a drawer, you might be looking at a piece of American history. To accurately determine your coin’s worth, you can use a top coin identifier app to verify the “S” mint mark and the design. The 2018 Native American Dollar features the iconic portrait of Sacagawea on the obverse, carrying her infant son, Jean Baptiste. However, the 2018 reverse is unique, commemorating Jim Thorpe, the legendary athlete from the Sac and Fox Nation.

The “S” mint mark on the edge of the coin indicates it was produced at the San Francisco Mint. Unlike the “P” (Philadelphia) or “D” (Denver) versions, the 2018-S was exclusively minted as a Proof coin. This means it was struck using special dies and polished planchets to create a mirror-like finish. CoinKnow users often find that these coins are more common than they expect because they were sold in official U.S. Mint sets.

Most people are surprised to learn that these coins were not released into circulating bank bags. If you see one with heavy scratches or dull surfaces, it likely escaped from a collector set and spent some time in the “wild.” Even in such cases, it retains its status as a collector-item-only issue, though its premium over face value will be significantly diminished compared to a pristine specimen.

The “Proof” Factor and Market Value

Proof coins are the “supermodels” of the numismatic world. In 2018, the San Francisco Mint struck 976,513 Proof Sacagawea dollars. Because they were handled with care by the mint and sold in plastic lenses, many have survived in excellent condition. To get an accurate reading on current market trends, checking a 2018 Native American Dollar price guide can help you see how the “S” proof compares to the Philadelphia business strikes.

The value of a 2018-S Proof Sacagawea Dollar depends heavily on whether it achieved a “Deep Cameo” (DCAM) designation. A Deep Cameo coin has a heavy frost on the raised details (the design) and a deep, mirror-like reflection on the flat fields. Collectors pay a significant premium for coins that look visually striking. If your coin has a hazy or milky look, its value will stay at the lower end of the spectrum, usually around $5.

For those looking to sell, the CoinKnow app can help you photograph the coin to see if the luster is original. Remember that cleaning a coin can actually destroy its value. A 2018-S with “cleaning scratches” is worth little more than its face value of one dollar, as collectors demand original surfaces for modern proof issues.

2018-S Sacagawea Dollar Price Chart by Grade

When professional grading services like PCGS or NGC evaluate a coin, they use a 70-point scale. For proof coins, the scale runs from PR1 to PR70. Because the 2018-S was protected in sets, most are at least PR67 or higher. To understand the jump in prices for higher grades, look at the latest 2018 Sacagawea dollar valuation data.

Numerical Grade	Designation	Current Market Value
PR67	Proof	$5 – $7
PR68	Deep Cameo	$12 – $15
PR69	Deep Cameo	$20 – $28
PR70	Deep Cameo	$85 – $115

The difference between a PR69 and a PR70 is invisible to the untrained eye, but it can mean a $100 difference in price. A PR70 coin is theoretically “perfect” under 5x magnification. Unless your coin was sent to a grading service and comes in a sealed plastic slab with that label, it is safer to assume it is a PR68 or PR69.

The Jim Thorpe Reverse Design Importance

The 2018 edition of the Native American Dollar series is particularly beloved because of the reverse design. It features Jim Thorpe, widely considered one of the greatest athletes of the 20th century. The design includes headdresses, Thorpe’s jersey number (21), and symbols representing his Olympic achievements and football career.

Collectors of sports memorabilia often cross over into coin collecting for this specific year. This “thematic demand” often keeps the 2018-S prices more stable than other years in the series. If you use CoinKnow to browse recent auctions, you may notice that the Jim Thorpe dollar gets more “bids” than the 2017 or 2019 versions.

Because the United States Mint stopped producing Sacagawea dollars for general circulation in 2011, the only way to get a 2018 coin was to buy it directly from the Mint or a coin dealer. This “Not Intended For Circulation” (NIFC) status is the primary reason why even a “circulated” 2018-S is worth more than its one-dollar face value.

The Difference Between Proof and Reverse Proof

In 2018, the Mint also released a special “Reverse Proof” version as part of a 2018 Native American Coin & Currency Set. While the standard 2018-S Proof has shiny backgrounds and frosted designs, the Reverse Proof has frosted backgrounds and shiny, mirrored designs. These are rarer and often command higher prices.

Coin Type	Mintage	Average Raw Value
2018-S Standard Proof	~976k	$5 – $10
2018-S Reverse Proof	~75k	$40 – $60

If you find a 2018-S that looks “backwards”—where the person’s face is shiny like a mirror but the background is matted—you have found the Reverse Proof. These are much scarcer than the standard “S” proof and should be handled with extreme care. Touching the surface of a Reverse Proof with your bare fingers can leave permanent oils that lower the grade significantly.

Where to Sell Your 2018 Sacagawea Dollar

If you have confirmed your coin’s value and are ready to sell, you have several options. For a single coin worth $5-$10, local coin shops might not be interested because their profit margin is too low after they pay you and try to resell it. However, if you have a “perfect” PR70 specimen or a Reverse Proof, you have a valuable asset.

Online marketplaces like eBay are the most popular venues for selling these modern dollars. Be sure to take high-quality, clear photos of the edge of the coin (where the mint mark and date are located) as well as the front and back. Alternatively, listing your coin on numismatic forums or through a dedicated app can connect you directly with collectors who are missing this year in their Jim Thorpe or Sacagawea collections.

Regardless of where you sell, always check the most recent “Sold” listings rather than “Asking” prices. People can ask for $1,000 for a common coin, but it only matters what someone actually paid.

FAQ

Q: Why is the date and mint mark on the edge of the 2018-S Sacagawea Dollar?

A: Starting in 2009, the U.S. Mint moved the date, mint mark, and the motto “E Pluribus Unum” to the edge of the coin to allow for a larger, more artistic design on the front and back. If you don’t see the date on the face of the coin, just flip it on its side!

Q: Is there any gold in the 2018 Sacagawea Dollar?

A: No, there is no actual gold in these coins. They are made of a “manganese-brass” alloy coated over a pure copper core. The manganese gives the coin its distinctive golden hue, but it is purely for aesthetic reasons and has no precious metal value.

Q: I found a 2018-S in my pocket change. Is it still worth money?

A: Yes! Because these were only sold to collectors, finding one in circulation is rare. Even if it is scratched or dull, it is likely worth $2 to $3 to someone looking for an “album filler.” It is always worth more than its $1 face value.

Q: How can I tell the difference between a Philadelphia and San Francisco 2018 coin?

A: Look at the edge of the coin. You will see either a small “P”, “D”, or “S”. The “S” stands for San Francisco and will almost always have a much shinier, mirror-like finish than the “P” or “D” versions, which were made for collectors in standard finishes.
