Understanding the 2009-S James K. Polk Presidential Dollar
The 2009-S James K. Polk Dollar was the eleventh release in the United States Mint’s Presidential $1 Coin Program. Unlike the P and D mint marks you might find in your pocket change, the “S” mint mark signifies that this coin was produced at the San Francisco Mint. These were struck as “Proof” coins, intended for collectors rather than for spending at the grocery store. If you are unsure exactly what version you have, using a top coin identifier and value app can help you distinguish between a common business strike and a collector proof.
James K. Polk served as the 11th President of the United States, and his legacy is captured on the obverse (heads) of this coin. The “S” mint mark is located on the edge of the coin, a unique design feature of this series. Because these coins were sold in protective sets, they usually retain a high level of shine and detail. If you happen to find one in a loose change jar, it likely escaped from a broken collection.

What Determines the 2009-S Polk Dollar Coin Value?
When evaluating the 2009-S James K. Polk Dollar value, the primary factor is the “Grade.” Collectors use a scale from 1 to 70. Since all “S” minted Polk dollars are proof coins, they start at a high baseline. However, the difference between a PR 68 and a PR 70 (a perfect coin) can be hundreds of dollars. Surface scratches, fingerprints, or “haze” on the coin can significantly lower the price.

Another major factor is the visual contrast. Most modern proofs are “Deep Cameo” (DCAM), meaning the portrait is frosted and the background is mirror-like. If yours has this striking contrast, it is much more desirable. You can check the current market rates for 2009 dollar coins to see how different finishes affect the final auction price. Standard proof versions are quite common, but perfect specimens are rare and highly sought after by registry set collectors.
| Grade (PCGS/NGC) | Deep Cameo Price | Mintage |
|---|---|---|
| PR 67 DCAM | $5.00 | 2,809,452 |
| PR 68 DCAM | $8.00 | (Total Proof Mintage) |
| PR 69 DCAM | $15.00 | Low Availability |
| PR 70 DCAM | $55.00 – $110.00 | Very Rare |
Identifying Rare Errors in 2009 Presidential Dollars
While the 2009-S Polk Dollar coin is generally well-made, collectors always hunt for mint errors. In the Presidential Dollar series, the most common errors involve the “Edge Lettering.” Because the year, mint mark, and “E Pluribus Unum” are inscribed on the edge, sometimes this step was missed or doubled. However, edge errors are far more common on the P and D circulation strikes than on the S proofs.

If you believe you have found a unique variation, it is worth comparing it against a 2009 Presidential Dollar price guide to see if your error is recognized by the numismatic community. Common errors include “Missing Edge Lettering” or “Double Edge Lettering.” In the case of the Polk dollar, these errors can take a $4 coin and turn it into a $50 or $100 treasure. Using CoinKnow can help you zoom in on these tiny details to see if your coin has those rare characteristics.
The “S” Mint Mark and the Proof Striking Process
The “S” mint mark is the hallmark of the San Francisco Mint. Unlike the high-speed presses used in Philadelphia or Denver, the San Francisco Mint uses a specialized process for proof coins. Each 2009-S James K. Polk Dollar blank was polished before being struck twice by specially prepared dies. This process ensures that every detail of the design is sharp and clear.

This is why, if you find one of these, it likely looks much better than a standard quarter or penny. The copper-zinc-manganese-nickel composition gives it a bright “golden” appearance, although it contains no actual gold. Because the mintage for the 2009-S proof was limited to approximately 2.8 million sets, there are far fewer of these than the 88 million combined P and D versions. This relative scarcity is what keeps the 2009-S J.K. Polk Dollar value stable for collectors.
| Mint Location | Strike Type | Approx. Value Range |
|---|---|---|
| Philadelphia (P) | Business Strike | $1.00 – $3.00 |
| Denver (D) | Business Strike | $1.00 – $3.00 |
| San Francisco (S) | Proof Strike | $4.00 – $100.00+ |
How to Store and Protect Your Polk Dollar
Because the value of the 2009-S Polk Dollar is so heavily dependent on its mirror-like finish, proper storage is essential. If you touch the surface of a proof coin with your bare hands, the oils from your skin can cause “milk spots” or permanent cloudiness over time. Collectors recommend holding the coin only by its edges.
If you have a coin that looks perfect, consider putting it in a plastic “flip” or a hard plastic capsule. This prevents air and moisture from oxidizing the metal. For those who think they have a PR 70 candidate, professional grading by services like PCGS or NGC is the only way to realize the maximum 2009-S J.K. Polk Dollar value. Before spending money on grading fees, you can use CoinKnow to get a preliminary idea of whether your coin is high enough quality to justify the cost.
