The 2009-S J.K. Polk Dollar is worth anywhere from $4 in standard proof condition to over $50 for high-grade specimens. While these golden-colored coins often catch the eye of non-collectors, understanding the specific value of the “S” mint mark version is key to knowing if you’ve found a keeper.
| Coin Condition | Estimated Value |
|---|---|
| PR-65 (Choice Proof) | $4.00 – $6.00 |
| PR-69 (Near Perfect) | $12.00 – $18.00 |
| PR-70 (Perfect Proof) | $45.00 – $75.00 |
Understanding the 2009-S James K. Polk Presidential Dollar
If you have recently discovered a shiny golden coin featuring the 11th President of the United States, you are looking at part of the Presidential $1 Coin Program. The United States Mint launched this series to honor our nation’s leaders, releasing four different designs each year. James K. Polk was the third president honored in 2009.
Many people find these in change and wonder if they have struck gold. However, it is important to note that these coins are made of a manganese-brass alloy, not real gold. Using a top coin identifier app can help you quickly distinguish between common circulation strikes and the more valuable proof versions minted in San Francisco.
The “S” mint mark signifies that the coin was produced at the San Francisco Mint. Unlike the “P” (Philadelphia) or “D” (Denver) versions, these were never intended to be spent in grocery stores or vending machines. They were created specifically for collectors as part of annual Proof Sets, which gives them a higher baseline value than their circulating cousins. If you want to compare your find to other modern dollars, checking the 2009-P Native American dollar value can provide great context on the year’s production.

Identifying the S Mint Mark and Proof Finish
To determine the true 2009-S J.K. Polk Dollar value, you must first verify that you actually have an “S” mint mark coin. On Presidential Dollars, the mint mark is not on the face of the coin. Instead, it is located on the edge. You will need to turn the coin on its side to find the year, the mint mark, and the motto “E Pluribus Unum.”
Proof coins are manufactured using a specialized process. The blanks are polished, and the dies are treated to create a contrast between a frosted portrait and a mirror-like background (field). If your coin looks exceptionally shiny—almost like a mirror—and features the “S” on the edge, you have a proof coin.

You can simply snap a photo, and the AI helps identify whether your coin is a standard business strike or a collector’s proof. Knowing this distinction is the first step in realizing the 2009 Presidential Dollar price guide estimates.
| Mint Mark | Production Type | Rarity Level |
|---|---|---|
| P (Philadelphia) | Circulation | Common ($1.00) |
| D (Denver) | Circulation | Common ($1.00) |
| S (San Francisco) | Proof | Colletible ($4+) |
The Grading Factor: Why Content Matters
Value in the coin world is almost entirely dependent on “grade.” Grade refers to the physical condition of the coin on a scale from 1 to 70. Since the 2009-S J.K. Polk Dollar was sold in protective plastic lenses from the Mint, many have survived in nearly perfect condition.

A coin with even a single tiny scratch or a “milk spot” (a white cloudy patch caused by cleaning agents at the Mint) will see its value drop. Collectors are very picky. They want coins that are graded PR-69 or PR-70. A PR-70 coin is considered “perfect” even under 5x magnification.
If you find a Polk dollar in your pocket change that has the “S” mint mark, it was likely “broken out” of a set and spent. This is called an “impaired proof.” While it is still technically a proof coin, its value drops significantly because it has scratches from touching other coins. These are usually worth only $1.50 to $2.00 to a casual collector.
James K. Polk Dollar Errors to Watch For
While major errors are rare for the San Francisco proof strikes, they are not impossible. Collectors often look for “Edge Lettering” errors on Presidential Dollars. On some coins, the lettering on the rim might be missing entirely, or it might be doubled.

Because the “S” proofs were handled with more care than the Philadelphia and Denver coins, finding an error on a 2009-S Polk dollar is like finding a needle in a haystack. If you do find one, however, the value could skyrocket from a few dollars to several hundred.
Always check the edge carefully. If the letters look strange or if the surface of the edge is smooth where it should have writing, it is worth consulting with a professional or using the CoinKnow community forums to get a second opinion.
| Potential Error Type | Check For… | Estimated Premium |
|---|---|---|
| Missing Edge Lettering | Smooth edge with no text | $50 – $100+ |
| Double Edge Lettering | Overlapping text on the side | Varies |
| Deep Cameo (DCAM) | High contrast frost/mirror | Standard for S-Mint |
How to Sell Your 2009-S Polk Dollar
If you have confirmed your coin is a proof and it’s in great shape, you might be wondering where to sell it. For a single coin worth $5-$10, local coin shops might not be interested as they need to make a profit margin. Your best bet for a quick sale is often a platform like eBay.

When listing your coin, take clear, high-resolution photos of both the front (obverse), the back (reverse), and most importantly, the edge (rim) to show the “S” mint mark. This builds trust with buyers. Mention if the coin is in its original government packaging (OGP), as this often helps it sell faster.
