The 2020 S Weir Farm Quarter is worth anywhere from $0.25 in circulated condition to over $50 in high-grade silver proof condition. This commemorative coin was part of the America the Beautiful series, and depending on which version you hold in your hand, it could be a simple spender or a collectible treasure.

Coin Version	Average Value (Circulated)	Uncirculated/Proof Value
2020 S Clad Business Strike	$0.25 – $1.00	$2.00 – $5.00
2020 S Clad Proof	$1.50	$5.00 – $10.00
2020 S Silver Proof	$15.00	$35.00 – $60.00

Understanding the Scarcity of the 2020 S Weir Farm Quarter

If you just looked at your change and saw a “S” mint mark on your 2020 Weir Farm quarter, you might be excited to think you’ve found a rarity. To identify exactly what you have, many hobbyists use a top coin identifier app to distinguish between clad and silver versions.

The San Francisco Mint (S) usually produces coins exclusively for collectors in proof sets. However, in 2020, they also produced a limited number of “business strike” circulating quarters for bulk purchase by collectors.

Unlike the common Philadelphia (P) or Denver (D) coins, the S-minted versions were never intended for general circulation. If you find one in your pocket, it likely escaped from a collector’s set.

Checking your coins with CoinKnow can help you figure out if that shiny surface is a proof finish or just a well-preserved business strike.

Distinguishing Clad vs Silver Weir Farm Proofs

Not all S-branded quarters are made of the same metal. In 2020, the U.S. Mint produced both Copper-Nickel Clad proofs and 99.9% Fine Silver proofs. The silver version is significantly more valuable due to its precious metal content and lower mintage numbers.

To tell them apart, look at the edge of the coin. If you see a solid silver-colored edge without a copper stripe, you likely have the silver version. The weight is also a giveaway; silver quarters weigh 6.25 grams, while clad ones weigh 5.67 grams.

Collectors often compare these finds to other 2020 releases, noting that the 2020 National Park of American Samoa quarter value often follows similar pricing trends for its S-minted varieties. Understanding these nuances is key to determining if you should spend your change or save it in a protective holder.

Composition	Weight	Estimated Mintage
Copper-Nickel Clad	5.67g	~460,000 (standard)
.999 Fine Silver	6.25g	~380,000

The Design and History of the Weir Farm Quarter

The 2020 Weir Farm National Historic Site quarter is the 52nd release in the America the Beautiful Quarters Program. The reverse design features an artist, wearing a smock, painting on a canvas outside Julian Alden Weir’s studio.

This design pays homage to the Impressionist tradition at the Connecticut site. While the 2020 S version is sought after, the P and D versions from this year also see high demand in high grades.

Detailed America the Beautiful quarter market prices show that as these coins age, the gap between “pocket change” and “museum quality” grows wider every year.

Because many of these were minted during a year of coin shortages, finding any 2020 quarter in pristine condition is becoming increasingly difficult for the average hunter.

How Grading Affects Your Coin’s Value

Grading is the process of determining a coin’s condition on a scale from 1 to 70. For the 2020 S Weir Farm quarter, a grade of Proof 70 (perfect) can skyrocket the price compared to a Proof 65.

Proof coins are struck twice with special dies to give them a mirror-like background and frosted details. If your S-mint quarter looks like a mirror, it is a proof.

If it looks like a normal quarter but has an S mint mark, it is a “Business Strike” S-mint coin, which is actually rarer in terms of mintage than many of the common P and D coins you see every day.

Using an app like CoinKnow can assist you in identifying surface marks or “milk spots” that might lower the grade and value of your collection.

Condition Grade	Clad Value	Silver Value
MS65 (Uncirculated)	$5.00	N/A (Proofs only)
PR69 (Near Perfect)	$12.00	$40.00
PR70 (Perfect)	$35.00	$90.00+

What About Errors and Rarities

While the 2020 S Weir Farm quarter is mostly known for its low mintage as a proof or collector strike, you should also keep an eye out for mint errors. Errors can occur regardless of the mint mark.

Some collectors look for “Doubled Die” errors, where the design appears to be stamped twice, creating a blurry or “ghost” effect on the letters or the artist’s easel.

While no major famous errors have been widely reported for the Weir Farm specifically, 2020 was a year of high production pressure, making minor “die chips” or “grease strikes” quite common.

If you find something that looks unusual, don’t clean it! Cleaning a coin can destroy its numismatic value instantly. Instead, compare it with listings in CoinKnow to see if others have found something similar.

Final Tips for Coin Hunters

When looking for the 2020 S Weir Farm quarter, remember that patience is key. Most of these coins are still in the hands of people who don’t realize they have a San Francisco mint mark.

Always check the mint mark, which is located to the right of George Washington’s ponytail on the obverse (front) of the coin. If it’s a P or D, it’s likely worth just 25 cents. If it’s a W, it’s a West Point mint mark and is worth $10-$20 right away!

If it’s an S, you have something special that was likely broken out of a set. Hold onto it, keep it in a soft flip or a cardboard holder, and watch the market as these modern commemoratives continue to gain interest among new collectors.

FAQ

Q: Why is there an S on my 2020 Weir Farm quarter?

A: The “S” stands for the San Francisco Mint. These coins were originally produced for collectors as part of proof sets or special mint bags and were not intended for general circulation.

Q: Is the Weir Farm quarter made of real silver?

A: Most 2020 S quarters found in change are “clad” (copper and nickel). However, the U.S. Mint did produce a “Fine Silver” version for collectors. Check the edge of the coin; if it has a copper stripe, it is clad.

Q: How much is a 2020 W Weir Farm quarter worth?

A: While this article focuses on the “S” mint mark, the “W” (West Point) version is also very valuable, typically selling for $15 to $30 because only 2 million were made for circulation.

A: You can sell your coins to local coin shops, through online auction sites like eBay, or to collectors in specialized coin groups. High-grade specimens should be professionally graded before sale to maximize profit.

Q: What is the most valuable 2020 quarter?

A: Generally, the 2020 W quarters or the 2020 S Silver Proofs in perfect PF70 condition command the highest prices, sometimes exceeding $100 depending on the specific park design and grade.
