The 2009-S Puerto Rico Quarter is worth anywhere from $3 in standard proof condition to over $1,200 for rare silver specimens in perfect grades. Whether you found one in a change jar or inherited a collection, these US Territorial quarters carry a significant premium over face value.

Coin Version	Estimated Value (Ungraded)	High Grade Value (PF/PR 70)
2009-S Clad Proof	$3 – $5	$15 – $25
2009-S Silver Proof	$12 – $15	$40 – $1,250+

History of the 2009-S Puerto Rico Quarter

In 2009, the United States Mint expanded the incredibly popular State Quarters program to include the District of Columbia and five U.S. Territories. The Puerto Rico design was the second release in this special six-coin series. Unlike the standard 2009 quarters minted in Philadelphia or Denver for general circulation, the “S” mint mark quarters were produced exclusively at the San Francisco Mint.

Finding one of these in your pocket change is quite rare. Because they were originally sold in “Proof Sets” intended for collectors, any 2009-S quarter found in the wild is usually a “proof escapee”—a coin someone spent by accident. If you aren’t sure if your coin is a standard strike or a special proof, using a top coin identifier app can help you distinguish the mirror-like finish of a San Francisco strike from a common circulation coin.

The design itself is rich in heritage, featuring a historic sentry box (garita) from a fort in Old San Juan and the beautiful hibiscus flower. Because these were minted during the Great Recession, mintage numbers across all 2009 quarters were significantly lower than previous years. This scarcity is a primary reason why the CoinKnow app often flags 2009 territorial quarters as coins with higher potential value than their 1999-2008 predecessors.

Identifying Clad vs. Silver Proof Versions

One of the most important factors in determining the 2009 Puerto Rico quarter value is the metal composition. The San Francisco Mint produced two distinct versions of the 2009-S: the copper-nickel “clad” proof and the 90% silver proof. While they may look similar to the untrained eye, their market prices are vastly different.

The clad version has a copper core that is usually visible on the edge of the coin. If you see a distinct orange or reddish stripe on the rim, it is the standard clad version. However, if the edge is solid silver/white with no copper visible, you likely have the 90% silver version. To be 100% certain, you can weigh the coin; a clad quarter weighs 5.67 grams, while a silver quarter weighs 6.25 grams.

Collectors often use the CoinKnow app to track the current spot price of silver, which provides a “floor” value for the silver versions. Even in damaged condition, a 2009-S Silver Puerto Rico quarter is always worth at least its weight in precious metal, whereas a clad proof’s value is entirely dependent on its visual appeal and “S” mint mark status.

Feature	Clad Proof (S)	Silver Proof (S)
Composition	Copper-Nickel	90% Silver, 10% Copper
Weight	5.67 grams	6.25 grams
Edge Appearance	Brown/Copper Stripe	Solid Silver/White

Understanding Gradings and “Deep Cameo”

When researching the 2009-S Puerto Rico Quarter value, you will often see the term “Deep Cameo” (DCAM) or “Ultra Cameo.” This refers to the contrast between the frosted, white-looking portrait/design and the mirror-like, shiny background (fields). Modern proof coins from San Francisco are designed to have this high-contrast look, which is highly sought after by collectors.

The condition of a coin is graded on a scale of 1 to 70. A grade of PR70 (Proof 70) represents a perfect coin with no visible flaws under 5x magnification. For the 2009-S Puerto Rico Silver Quarter, a PR70 Deep Cameo can command prices upwards of $500, especially if it is certified by a professional grading service like NGC or PCGS. Even the clad version in a perfect 70 grade can sell for $20 to $40.

Most coins found in pocket change will likely grade between PR60 and PR63 because of light scratches or “bag marks.” At these lower levels, the coins are still worth more than 25 cents, but they won’t make you rich overnight. For a quick assessment of your coin’s condition, the CoinKnow tool provides high-resolution photo comparisons to help you decide if it is worth sending your quarter to a professional grader.

Market Trends and Rarity

The mintage for the 2009-S Puerto Rico Proof quarters is relatively low compared to the billions of state quarters minted during the early 2000s. The Mint produced approximately 2,113,490 clad proofs and 996,548 silver proofs. While two million might sound like a lot, in the world of US coinage, it is considered a limited release.

Over the last few years, interest in the 2009 Territorial quarters has increased. Many collectors who missed the initial release are now trying to complete their sets. This steady demand, combined with the low mintage, has kept the 2009-S Puerto Rico Quarter value stable. Silver versions have seen even more growth due to the rising price of bullion and the fact that many of these coins were broken out of sets and lost to the elements.

If you are looking to sell, it is best to check auction records from the last six months. Auction sites and coin shows are the best places to see what buyers are actually paying. Keep in mind that a coin dealer must buy below market price to make a profit, so “book value” might be higher than what a local shop will offer you in cash.

Condition/Grade	Clad Value	Silver Value
Proof (Ungraded)	$3.50	$14.00
PR65 (Choice)	$6.00	$22.00
PR69 (Near Perfect)	$12.00	$35.00
PR70 (Perfect)	$30.00+	$500 – $1,200+

Common Errors to Look For

While proof coins are usually inspected more rigorously than circulation coins, errors can still happen. Collectors of the 2009-S Puerto Rico Quarter often look for “Double Dies.” A doubled die error occurs when the hub strikes the die multiple times, leaving a slightly offset image. Look closely at the lettering in “PUERTO RICO” or “E PLURIBUS UNUM” to see if there is any doubling or “extra thickness.”

Another error to check for is the “Struck Through” error. This is when a foreign object, like a piece of lint or grease, gets caught between the die and the coin blank. This leaves a ghost-like impression or a blur on the coin’s surface. These errors are quite rare on proof coins because the quality control at the San Francisco Mint is very high, but finding one could significantly multiply the 2009-S Puerto Rico Quarter value.

If you think you see something unusual on your quarter, don’t clean it! Cleaning a coin with chemicals or cloth can destroy its value by scratching the delicate mirror surface. Instead, use a magnifying glass or a high-resolution camera to document the error. Many hobbyists use the CoinKnow community forums to get opinions from other experts on whether their find is a true error or just post-mint damage.

How to Store Your 2009-S Quarter

If you find that your 2009-S Puerto Rico Quarter is in excellent condition, you must protect it to maintain its value. Proof coins are particularly sensitive to environmental factors. The oils from your skin can leave permanent fingerprints on the surface, which will eventually turn into “toning” or dark spots.

Always handle the coin by its edges, or better yet, wear lint-free cotton gloves. For long-term storage, use PVC-free plastic “flips” or hard plastic capsules. Avoid keeping coins in wooden boxes or paper envelopes that contain sulfur, as this will cause the silver versions to tarnish or turn black over time.

Proper storage ensures that if you decide to sell your quarter in ten or twenty years, it will still be in “Gem” condition. A high-quality 2009-S silver proof could be a fantastic heirloom or a building block for a larger collection of U.S. Territorial coins.

FAQ

Q: Why does my 2009 Puerto Rico quarter have an “S” instead of a “P” or “D”?

A: The “S” mint mark stands for San Francisco. In 2009, the San Francisco Mint only produced proof coins for collectors. If yours has an “S,” it was originally part of a special set and was not intended for general circulation.

Q: Is every 2009-S Puerto Rico quarter made of silver?

A: No. There are two types. The clad version is made of copper and nickel, while the silver version is 90% silver. You can tell the difference by looking at the coin’s edge or weighing it (the silver version is heavier).

Q: Can I find a 2009-S Puerto Rico quarter in my change?

A: It is possible, but rare. Most of these coins are found in the hands of collectors. If you find one in change, it is often because someone accidentally spent a coin from a collection. These are called “circulated proofs” and are usually worth $1 to $3.

Q: How much is a 2009-S Silver Puerto Rico quarter worth in melt value?

A: Since the quarter contains roughly 0.18 ounces of pure silver, its “melt value” fluctuates with the silver market. Generally, the metal alone is worth around $4 to $6, but the numismatic (collector) value is usually much higher.

Q: What is the most expensive 2009-S Puerto Rico Quarter ever sold?

A: High-grade silver examples (PR70 Deep Cameo) have sold at major auctions for over $1,200. These prices are only achieved by coins that are officially graded and “slabbed” by professional services like PCGS.
