The 2010-S James Buchanan Dollar is worth anywhere from $4 in standard proof condition to over $50 in deep cameo gem grades. If you have found one of these shiny, gold-colored coins in your pocket change or an old collection, you are likely holding a piece of history minted specifically for collectors rather than daily spending.

Condition / Grade	Estimated Market Value
PR 65 (Proof)	$4.00 – $6.00
PR 69 (Deep Cameo)	$12.00 – $18.00
PR 70 (Perfect Grade)	$45.00 – $75.00

Overview of the 2010-S James Buchanan Dollar

The 2010 James Buchanan Presidential Dollar is part of the United States Mint’s Presidential $1 Coin Program, which honored each U.S. President in the order they served. James Buchanan, the 15th President, is featured on the 2010 release. While the P (Philadelphia) and D (Denver) versions were made for circulation, the “S” mint mark indicates the coin was struck at the San Francisco Mint.

If you’re unsure which version you have, utilizing a top coin identifier app can help you distinguish between a standard business strike and the high-gloss proof versions. Unlike the coins you find at the grocery store, the “S” mint mark version was never intended to be spent. These were sold in official proof sets to hobbyists.

Because they were handled with care and stored in protective plastic lenses, finding one in high grade is common. However, finding one in “Perfect 70” condition is what every collector dreams of. Using CoinKnow can provide you with real-time updates on what these perfect specimens are currently fetching at major auction houses.

Technical Specifications and Design Details

Understanding the physical makeup of your coin is vital for authentication. The 2010-S Buchanan Dollar is not made of gold, despite its yellowish appearance. It features a manganese-brass clad composition over a pure copper core. The obverse displays a portrait of James Buchanan, while the reverse shows the Statue of Liberty, designed by Don Everhart.

One unique feature of this series is the edge-incused lettering. The date, the mint mark, and the mottos “E Pluribus Unum” and “In God We Trust” are engraved into the edge of the coin. For proof coins, the San Francisco Mint took extra care to ensure these letters are sharp and well-defined.

Composition	88.5% Copper, 6% Zinc, 3.5% Manganese, 2% Nickel
Weight	8.10 grams
Diameter	26.5 mm
Mint Mark	S (San Francisco)

Determining the 2010-S Proof Dollar Value

The value of a 2010-S James Buchanan dollar is heavily dependent on its “Cameo” effect. Proof coins are struck twice using polished dies, resulting in a mirror-like background and frosted foreground. Collectors look for “Deep Cameo” (DCAM) designations from grading services like PCGS or NGC. A coin that lacks this contrast will be worth significantly less.

Most 2010-S Buchanan dollars stay within the $4 to $10 range because millions were produced (specifically 2,858,361 units). To get a better sense of how these compare to other issues, you can check the 2010 dollar current auction prices to see how different presidential and Native American dollars are performing in today’s market.

Prices for these coins are relatively stable, but a sudden interest in completing Presidential sets can drive premiums up. If you’re looking to sell, having a high-quality photo and knowing the specific grade will make your listing much more attractive to buyers.

Is Your 2010 James Buchanan Coin an Error?

Error coins are the holy grail for many “everyday” finders. In the Presidential Dollar series, common errors include missing edge lettering or “weak” strikes. However, because the 2010-S is a proof coin, the quality control at the San Francisco mint was incredibly strictly. Errors on 2010-S Proofs are extremely rare.

Most “errors” reported by beginners are actually post-mint damage (PMD). If your coin looks “silver,” it might have been dipped in chemicals or plated by a third party as a novelty. These alterations actually decrease the value to its face value of one dollar. For a detailed breakdown of what makes these coins special, you can view the 2010 dollar coin price and info guide.

Checking for doubled dies on the portrait or the lettering is another way to find hidden value. While no major doubled die varieties are widely recognized for the 2010-S Buchanan at this time, eagle-eyed collectors are always searching. Using a tool like CoinKnow helps you keep a digital inventory of your finds while you research potential errors.

Collector Demand and Market Trends

The market for Presidential Dollars hit a peak during the initial release of the program, but it remains a popular “entry-level” series. Because the coins are affordable, they are often used to teach children about numismatics and American history. This steady demand from new collectors keeps the value of coins like the 2010-S James Buchanan dollar from dropping to face value.

In the current market, “registry set” collectors are the ones driving the high-end prices. These specialists compete to own the highest-graded specimen of every single coin in the series. If you happen to have a 2010-S in a PR70 Deep Cameo holder, you aren’t just selling a coin; you’re selling a “top-pop” item that a serious collector needs to complete their collection.

Year / Mint	Strikes Produced	Rarity Factor
2010-P Buchanan	36,820,000	Common
2010-D Buchanan	36,540,000	Common
2010-S Buchanan	2,858,361	Scarcer (Proof Only)

How to Care for Your Buchanan Dollar

If you have a 2010-S James Buchanan dollar, you must handle it correctly to preserve its value. The “S” Proof coins are highly susceptible to fingerprints. The oils from your skin can actually “eat” into the delicate finish of a proof coin, leaving permanent marks that lower the grade. Always handle your coins by the edges or wear lint-free cotton gloves.

Storing your coin in a PVC-free flip or a specialized coin album is the best way to ensure it doesn’t develop “haze.” Haze is a cloudy film that sometimes appears on proof coins due to environmental factors. A hazy 2010-S Buchanan will sell for the low end of the spectrum, usually just $2 or $3, whereas a crystal-clear deep cameo will always command a premium.

Before you consider spending it at the store, check the current market prices on CoinKnow. While it won’t make you a millionaire, selling a proof coin for $10 is much better than spending it for $1. Understanding the nuances of grading and preservation is what turns a casual coin finder into a successful collector.

FAQ

Q: Why is my 2010-S Buchanan dollar not in a proof set?

A: Many collectors “break” proof sets to sell the coins individually or to send them in for professional grading. If you found one in a single flip, it was likely once part of a larger 2010 United States Mint Proof Set.

Q: Is the 2010-S James Buchanan Dollar real gold?

A: No, it is not made of gold. The “Golden Dollar” series uses a manganese-brass alloy to achieve its color. The metal content consists mostly of copper, and it does not contain any precious gold or silver.

Q: Can I find the 2010-S mint mark in my change?

A: It is very rare but possible. Sometimes proof coins are spent by people who don’t know their value or by thieves who have stolen a collection. However, if you find one in change, it will likely be “impaired,” meaning it has scratches and wear that significantly reduce its collector value.

Q: What is the highest price ever paid for a 2010-S James Buchanan Dollar?

A: Perfect PR70 DCAM (Deep Cameo) specimens have sold for upwards of $100 in the past, though current market values usually hover around $50-$75 for these top-tier coins. Grade is the single most important factor for this specific coin.
