| PR 68 (Near Perfect) | $8.00 – $12.00 |

| PR 70 (Perfect Grade) | $45.00 – $120.00+ |
Understanding the 2007-S John Adams Dollar Value
If you just found a shiny golden dollar featuring the second U.S. President, you might be wondering if you’ve struck gold. While the coin looks like gold, it is actually composed of a copper core with a manganese brass cladding. The “S” on the edge signifies it was struck at the San Francisco Mint. To get an instant answer on your coin’s rarity, you can use a top coin identifier and value app to scan the details.
Unlike the Denver (D) or Philadelphia (P) versions found in gas station change, the “S” mint mark version was only sold in official U.S. Mint proof sets. This means they were handled with extreme care and never meant to touch a cash register. Most of these coins held by the general public were either removed from sets or part of a legacy collection.
When determining the price, collectors look for “Deep Cameo” (DCAM) effects. This is where the portrait of John Adams appears frosted and white, while the background fields are as reflective as a mirror. If your coin is scratched or dull, it loses much of its premium value very quickly. Using CoinKnow can help you distinguish between a common circulated strike and a high-value proof.

Technical Specifications and Edge Lettering
The Presidential Dollar series introduced a unique feature to modern American coinage: edge-incused lettering. This means the date “2007,” the mint mark “S,” and the mottos “E Pluribus Unum” and “In God We Trust” are stamped into the rim of the coin rather than the face.
This technical shift led to many famous errors in the Denver and Philadelphia business strikes, such as the “Godless Dollar” missing the edge text. However, for the 2007-S proof versions, errors are incredibly rare because the quality control in San Francisco was much stricter.

The coin weighs 8.1 grams and has a diameter of 26.5mm. Because the edge lettering is vital for identification, never try to clean a coin you think is valuable, as you might damage these fine details. Collectors often consult specialized 2007 Presidential dollar value information to ensure they aren’t missing a rare edge variant.
| Feature | Detail |
|---|---|
| Composition | 88.5% Copper, 6% Zinc, 3.5% Manganese, 2% Nickel |
| Weight | 8.10 Grams |
| Mint Mark Location | Edge of the Coin |
| Total Proof Mintage | Approx. 3,965,989 |
Grading and How It Affects Price
In the world of coin collecting, the “Grade” is everything. For the 2007-S Adams Dollar, the difference between a PR 69 and a PR 70 (the highest possible grade) can be $100 or more. A PR 70 coin is essentially flawless under 5x magnification, containing no milk spots, scratches, or dullness.

Most Americans who find these coins have them in “raw” or ungraded condition. If the coin has been touched by bare fingers, the oils from the skin may eventually cause “toning” or spots, which reduces the value for serious investors. Using CoinKnow allows you to compare your coin against high-resolution images of graded specimens.
Professionals at companies like PCGS or NGC provide the gold standard for grading. If you have a perfectly preserved 2007-S Adams dollar, it might be worth the fee to get it certified. For those tracking market trends, the latest pricing data for 2007 gold-toned dollars shows that high-grade proofs continue to hold a steady premium over their face value.
Common Errors to Look For
While errors are most common in the P and D mint marks, the 2007-S series is not entirely immune to manufacturing oddities. The most sought-after errors in this series usually involve the edge lettering. Look for “Double Edge Lettering,” where the rim text was applied twice, or “Missing Edge Lettering,” though this is nearly non-existent in proof strikes.

Another rare occurrence is the “Inverted Edge Lettering.” When the coin is held with the portrait facing up, the edge lettering can be right-side up or upside down. However, the U.S. Mint has officially stated that the orientation of edge lettering is random and not a recognized error, though some specialized collectors will still pay a small premium for specific orientations.
If you suspect you have an error coin, use CoinKnow to zoom in on the rim. Because proof coins are struck twice with higher pressure, the details should be razor-sharp. Any blurring or overlapping of letters could indicate a valuable minting mishap.
| Error Type | Rarity Status | Estimated Premium |
|---|---|---|
| Double Edge Lettering | Very Rare | $50 – $200 |
| Missing Edge Lettering | Extremely Rare (Proof) | $300+ |
| Significant Die Clashes | Rare | $20 – $50 |
Where to Sell Your 2007-S John Adams Coin
If you’ve identified that your coin is a high-grade “S” mint mark proof, you have several options for selling. For common PR 65 to PR 68 coins, online marketplaces like eBay are the most popular. You can list them individually or as part of a larger Presidential Dollar set.

Local coin shops are another option, though keep in mind that dealers need to make a profit. They will likely offer you about 50-60% of the retail value for lower-valued proofs. If you have a PR 70 specimen, auction houses like Heritage Auctions or GreatCollections are better venues for reaching serious investors willing to pay top dollar.
Always verify the current market demand before selling. The value of modern proofs can fluctuate based on how many “Perfect 70” graded coins are currently in the population report. A coin that was worth $150 five years ago might be worth $100 today if the supply has increased significantly.
Frequently Asked Questions
FAQ
Q: Is the 2007-S John Adams dollar made of real gold?
A: No. Despite its golden appearance, the coin contains no actual gold. It is made of a base metal alloy consisting mainly of copper, with a manganese brass outer layer that gives it the yellow color.
Q: Why is the date not on the front of the coin?
A: The Presidential Dollar series moved the date, mint mark, and mottos to the edge of the coin to allow for larger, more detailed portraits on the front (obverse) and the Statue of Liberty on the back (reverse).

Q: What does the “S” mint mark mean?
A: The “S” stands for the San Francisco Mint. Coins produced here are almost exclusively “Proof” coins, which are specially made for collectors using polished dies and planchets to create a mirror-like finish.
Q: How can I tell if my 2007-S John Adams coin is a “Proof”?
A: Look for a very shiny, mirror-like background and a frosted appearance on the portrait of John Adams and the Statue of Liberty. If the coin looks like a regular quarter or nickel with a flat finish, it is likely a D or P mint mark business strike, not an S proof.
Q: Is my coin worth more if it’s in a plastic case?
A: Often, yes. If the plastic case is from a professional grading service (like PCGS or NGC), it guarantees the grade and authenticity, making it much easier to sell for a higher price. If it is in the original U.S. Mint plastic lens, it should be kept there to maintain its “Proof” status.
