| Uncirculated (Business Strike) | $2.00 – $15.00 |

Understanding the 2020-S Weir Farm Quarter Mintage
The 2020 Weir Farm National Historic Site quarter was released as the 52nd installment of the America the Beautiful Quarters Program. This specific design honors the Connecticut home of impressionist painter Julian Alden Weir. If you are trying to identify this coin at home, using a top coin identifier app can help you distinguish between the different mint marks located on the obverse side.
The “S” mint mark signifies that the coin was produced at the San Francisco Mint. Unlike the “P” (Philadelphia) or “D” (Denver) quarters which are released into general circulation by the millions, San Francisco quarters from 2020 were largely produced for collectors.
This means that if you find a 2020-S quarter in your change, it likely came from an “S-Mint” roll or a proof set that someone broke open and spent. Because these were not intended for daily commerce, their scarcity automatically increases their market appeal. To stay updated on the latest market shifts, many enthusiasts use CoinKnow to track real-time auction results.

Differentiating Between Uncirculated and Proof Versions
Not all “S” mint quarters are created equal. The San Francisco Mint produced three distinct types of the 2020-S Weir Farm quarter: Copper-Nickel “Business Strike” (Uncirculated), Copper-Nickel Proof, and 99.9% Silver Proof. Identifying which one you have is crucial because the current value of 2020-S quarters varies wildly based on composition and finish.
The Business Strike “S” quarters have a standard satin look similar to what you see in your pocket. These were sold directly to collectors in bags and rolls. The Proof versions, however, feature a mirror-like background and frosted details.

If you suspect your coin is silver, check the edge; a silver quarter will not have a copper-colored stripe. Advanced collectors often rely on CoinKnow to identify these subtle visual differences that dictate whether a coin is worth a few dollars or nearly fifty dollars.
| Coin Type | Composition | Finish Type |
|---|---|---|
| 2020-S Clad Business | Copper-Nickel | Standard / Satin |
| 2020-S Clad Proof | Copper-Nickel | Mirror-like / High Shine |
| 2020-S Silver Proof | 99.9% Silver | Mirror-like / High Shine |
Factors That Influence the Weir Farm Quarter Value
Condition is the single most important factor when determining the worth of an “S” mint quarter. Coin grading is measured on a scale from 1 to 70. A coin that has been handled, scratched, or spent at a vending machine will rarely grade above “About Uncirculated.”
To reach high valuations, the coin must be in “Mint State” (MS), meaning it has no visible wear to the naked eye. Even small contact marks from other coins in a storage bag can reduce the grade. For those looking for precise data, referring to the detailed America the Beautiful quarter price guide can provide a benchmark for how different grades transition in price.

Furthermore, “Deep Cameo” (DCAM) designations on proof coins can significantly bump the price. This refers to the high contrast between the shiny background and the white, frosted design. Collectors often use tools like CoinKnow to compare their finds with professional images of high-grade specimens.
The Rarity of the 2020-S Business Strike Quarters
The 2020-S Weir Farm Business Strike (non-proof) quarter is particularly interesting to “everyday” collectors. The San Francisco Mint struck only 1,170,120 of these coins. While that may seem like a large number, it is tiny compared to the 280 million coins struck in Philadelphia.
Because these was never released into bank rolls, any 2020-S Weir Farm quarter you find in circulation is an outlier. Collectors call these “NIFC” (Not Intended For Circulation).

Finding one in a handful of change is like finding a small treasure. While it might only be worth a few dollars in “spent” condition, its rarity makes it a keeper. Most people who find these coins immediately place them in protective holders to prevent further degradation.
| Mint Location | Mintage Figure | Rarity Level |
|---|---|---|
| Philadelphia (P) | 280,800,000 | Common |
| Denver (D) | 155,000,000 | Common |
| San Francisco (S) | ~1,170,000 | Scarce |
Are There Any Errors on 2020 Weir Farm Quarters?
Error hunters are always looking for “doubled dies” or “clashing” on 2020 quarters. While no major, high-value errors have become famous for the Weir Farm specifically (unlike the “Bat Quarter” errors), there are always minor anomalies to look out for.
Some collectors have reported “die chips” on the reverse design, particularly around the painter’s easel or the artist’s palette. A die chip occurs when a small piece of the steel die breaks off, resulting in a raised lump of metal on the coin.
While a small die chip may only add $5 or $10 to the value, a significant “Struck Through” error or a “Broadstruck” error can double or triple the coin’s price. If you think you’ve found an error, compare it with known examples in the CoinKnow database to see if it’s a recognized variety.

How to Sell and Store Your 2020-S Quarter
If you’ve discovered a high-quality 2020-S Weir Farm quarter, you’ll want to preserve its condition. Oils from your skin can damage the surface of the coin over time. Handle it only by the edges and place it in a PVC-free plastic flip or a cardboard “2×2” holder.
Selling these coins is best done through online marketplaces or local coin shops. For circulated or lower-tier uncirculated “S” mint quarters, listing them on eBay as a “Found in Circulation” rarity often attracts impulsive buyers.
For coins that appear to be in perfect condition, consider professional grading by services like PCGS or NGC. A 2020-S Weir Farm quarter graded MS68 or MS69 can sell for hundreds of dollars at specialized numismatic auctions.
FAQ
Q: Why is there an “S” on my quarter instead of a “P” or “D”?
A: The “S” stands for the San Francisco Mint. While Philadelphia (P) and Denver (D) make coins for daily use, the San Francisco Mint typically produces coins for collectors and special sets.

Q: Is the 2020-S Weir Farm quarter silver?
A: Not necessarily. There are both copper-nickel and 99.9% silver versions of the “S” mint quarter. Check the edge of the coin; if you see a copper stripe, it is a standard clad coin. If the edge is solid silver/white, it is likely the silver proof version.
Q: Can I spend a 2020-S quarter at the store?
A: Yes, it is legal tender worth 25 cents. However, since it is worth at least $2 to $5 to a collector, spending it at face value is not recommended!
Q: How many Weir Farm quarters were made?
A: Between the Philadelphia and Denver mints, over 435 million were made. However, only about 1.17 million of the collectible “S” mint business strikes were produced, making them much harder to find.
