The 2009 S Northern Mariana Islands Quarter is worth anywhere from $3 in typical proof condition to over $50 for high-grade silver versions. Finding one of these in your change is a treat, as they were not intended for general circulation but were instead issued as part of the United States Mint’s 2009 District of Columbia and U.S. Territories Quarters Program.
The Unique History and Design of the Northern Mariana Islands Quarter
The Northern Mariana Islands quarter was the final release of the 2009 territorial series, making it a favorite for collectors who love completion. The reverse design features a wealth of cultural symbols, including a latte stone representing Chamorro architecture, a Carolinian outrigger canoe, and a decorative mwar (flower lei). These symbols reflect the rich heritage of the islands. Unlike the Philadelphia and Denver coins, the “S” mint mark quarters were produced at the San Francisco Mint specifically for collectors.
If you have stumbled upon a shiny quarter and wonder about its pedigree, using the best coin identifier app can help you distinguish between the different finishes. Because these coins were sold in sets, finding one in your pocket today usually means someone broke open a proof set to spend the change. While they look much shinier than a regular quarter, their value depends heavily on whether they are the standard Copper-Nickel clad version or the precious 90% Silver version. Many people use the CoinHix app to quickly scan their coins and determine which metal composition they have in their hands.
Understanding the Value of S Mint Mark Proof Quarters
The San Francisco Mint produced two distinct types of the 2009 S Northern Mariana Islands quarter. The first is the Clad Proof, made of the same copper-nickel alloy as standard pocket change but struck with specially polished dies. These generally sell for a few dollars. The second is the 90% Silver Proof, which carries intrinsic bullion value and higher numismatic demand. Collectors often pay a premium for эти coins because they were the last year before the America the Beautiful series began.
The 2009 Northern Mariana Islands quarter value is significantly higher for specimens that achieve a “Deep Cameo” (DCAM) designation. A Deep Cameo coin has a stark contrast between the frosted design elements and the mirror-like background fields. If your coin looks like a mirror, it is likely a proof.

| Condition / Variety | Estimated Market Value |
|---|---|
| 2009 S Clad Proof (PR65) | $2.50 – $4.00 |
| 2009 S Clad Proof (PR70 DCAM) | $15.00 – $25.00 |
| 2009 S Silver Proof (PR65) | $10.00 – $14.00 |
| 2009 S Silver Proof (PR70 DCAM) | $45.00 – $65.00 |
Identifying Clad vs Silver Northern Mariana Islands Quarters
Telling the difference between a clad proof and a silver proof can be tricky at first glance. The most reliable way is to look at the edge of the coin. If you see a distinct copper strip (a brownish-orange line) running along the rim, it is the standard clad version. If the edge is solid silver/white all the way through, you likely have the 90% silver version. This simple edge check could mean the difference between a $3 find and a $12 treasure.
Another method is to weigh the coin. A standard clad quarter weighs 5.67 grams, while the silver version is heavier, weighing 6.25 grams. Serious collectors often suggest using the CoinHix app to reference weight specifications when they are out hunting at estate sales or flea markets. Since the 2009 quarters had lower mintages than previous years, they are generally harder to find in high grades, which keeps the demand steady among enthusiasts.
How Mintage Figures Impact Your Coin’s Worth
The 2009 quarters are famous for having the lowest mintage numbers of the entire modern quarter era (1999–present). The Great Recession caused a drop in demand for new coins, so the Mint produced far fewer than usual. While the Philadelphia and Denver business strikes are rare in their own right, the “S” mint mark proofs were only produced in quantities of roughly 2.1 million for the clad version and under 1 million for the silver version.
In the world of coin collecting, lower supply often leads to higher prices over time. Because the Northern Mariana Islands was the sixth and final territory released in 2009, many people stopped collecting the sets before this one came out, making it slightly more elusive than the DC or Puerto Rico versions. Always handle your proof quarters by the edges to avoid leaving fingerprints, as oils from your skin can permanently damage the mirror finish and lower the resale value.
Q: Is a 2009 S quarter made of real silver?
A: It depends. The San Francisco Mint produced both a clad version (copper/nickel) and a 90% silver version. Check the edge of the coin; if it’s solid silver-colored with no copper stripe, it is likely silver.
Q: How can I tell if my 2009 S quarter is a proof?
A: Proof coins have a “S” mint mark and feature a mirror-like finish with frosted details. They are struck twice to create a high-quality appearance that stands out from regular circulating coins.
Q: Are there any valuable errors for the Northern Mariana Islands quarter?
A: While no major widespread errors are famous for this release, collectors look for “doubled die” errors on the latte stone and the outrigger canoe. These errors can increase the value significantly if verified.
