The 1986-S Washington Quarter is worth anywhere from $5 in deep cameo proof condition to over $40 in flawless PR70 grades. While you won’t retire on the value of a single coin, finding one in an old collection is a great way to start your numismatic journey.
| Condition / Grade | Estimated Value |
|---|---|
| PR65 (Proof) | $5.00 |
| PR67 (Proof DCAM) | $8.50 |
| PR69 (Proof DCAM) | $15.00 |
| PR70 (Perfect Proof) | $45.00+ |
What Makes the 1986-S Washington Quarter Special?
If you have found a quarter dated 1986 with a small “S” mint mark near the bottom of Washington’s neck, you are holding a “Proof” coin. Unlike the quarters you use at the vending machine, these were never intended for circulation. They were minted at the San Francisco Mint specifically for collectors using polished dies and specially prepared planchets (coin blanks). This extra care results in a mirror-like background and frosted details.
To determine if your specific coin has high-value characteristics, many hobbyists use the best coin identifier app to get an instant reading on the strike quality. Because 1986-S quarters were only sold in sets, you won’t find them in your pocket change unless someone broke open a collector set and spent it by mistake.
If you are trying to organize a multi-year collection, the CoinHix app can help you catalog these proof coins alongside their business-strike counterparts. While millions were made, only those kept in their original plastic lenses or those professionally graded by PCGS or NGC command premium prices over their face value.
Understanding the Value of San Francisco Mint Proofs
The value of a 1986-S Washington Quarter is almost entirely dependent on its visual “Cameo” effect. In the 1980s, the Mint mastered the “Deep Cameo” (DCAM) finish. This is where the portrait of George Washington looks snow-white and matte against a background that looks like a black mirror. If your coin looks dull or scratched, it is likely just worth its face value or a small premium to a casual collector.
However, professional grading can change the math significantly. Most 1986-S Quarters fall into the PR68 or PR69 category. A “Perfect” PR70 is rare because even a tiny microscopic hairline scratch from the minting machine can lower the grade. When comparing your find to 1986 quarter value guides, you’ll notice that most coins held in original United States Proof Sets maintain their value better than those handled with bare hands.

Grading and Quality: Is Your 1986-S a Deep Cameo?
When we talk about the price of these quarters, we use a 70-point scale. For proof coins like the 1986-S, the distinction between a $6 coin and a $40 coin is often invisible to the naked eye. Collectors look for “haze.” Over time, the chemicals in the air or the plastic packaging can create a milky film on the surface of the coin. A clean, haze-free 1986-S is much more desirable.
You should also look for “contact marks.” Since these quarters weren’t dropped into bags together, they shouldn’t have any nicks or scratches. If yours does, it was likely removed from its set. You can check the current market trends and 1986 Washington Quarter auction data to see how much “Imperfect” proofs sell for on sites like eBay.
Using an app like CoinHix allows you to take high-resolution photos of your 1986-S to check for these surface imperfections. If the coin has been touched by fingers, the oils from the skin will eventually turn into permanent dark spots, which significantly lowers the appeal to serious hobbyists who want “pristine” examples.
Rare Errors to Look For in 1986 Quarters
While the 1986-S is generally very high quality, errors can still occur. Error hunting is where the real money is in modern coin collecting. For the 1986-S, the most common thing to look for is a “Double Die.” This happens when the hub strikes the die twice at slightly different angles, leaving a ghosting effect on the lettering or the date.
Specifically, look at the words “LIBERTY” and the “1986” date. Even a slight doubling can make a standard $5 proof worth $50 or $100 to an error specialist. Another rare occurrence is a “Clipped Planchet,” where the coin looks like a bite was taken out of the side. These are very rare for proof coins because the quality control at the San Francisco Mint is much stricter than at other locations.
| Error Type | Visual Indicator | Potential Value |
|---|---|---|
| Doubled Die Obverse | Thickened or split letters | $25 – $100 |
| Off-Center Strike | Design is partially missing | $100+ |
| Proof Strike Thru | Thread or dust mark under finish | $15 – $30 |
Comparison: 1986-S vs. 1986-P and 1986-D Quarters
The biggest mistake new collectors make is confusing the common P and D quarters for the more valuable S proofs. In 1986, the Philadelphia (P) and Denver (D) mints produced over a billion quarters combined. These coins were made for daily transactions. Most are worn down and only worth 25 cents today.
The 1986-S is a different beast entirely. It was composed of a copper-nickel clad “sandwich,” just like the circulating coins, but it was struck multiple times to bring out the detail. If you find a 1986 quarter that looks exceptionally shiny, check for that “S.” If the “S” is missing and it’s just a shiny “P” or “D”, it might be a “Proof-Like” strike, but these rarely carry the same weight as the official San Francisco proofs.
To keep track of which mint marks are in your collection, CoinHix offers a comprehensive database. You can quickly toggle between mints to see which years have the lowest mintage. For 1986, the S-mint is by far the rarest, with only about 3 million minted compared to the roughly 500 million for the other two mints.
How to Store and Sell Your 1986-S Washington Quarter
If you have a 1986-S quarter, the most important thing is to not clean it. Cleaning a coin with polish or even soap and water will leave microscopic scratches that a professional grader will see immediately. This can turn a $40 coin into a “Damaged” coin worth only its metal content or face value.
The best way to store a proof coin is in a PVC-free plastic flip or a hard plastic capsule. If yours is already in the original 1986 Mint Proof Set (the purple packaging), it is best to leave it there. Taking it out exposes it to air and potential physical damage. If you decide to sell, check recent sold listings on eBay or take it to a reputable local coin shop.
When selling, remember that “ask” prices are not “sold” prices. Use the value charts provided here as a baseline for negotiation. Most dealers will offer you about 50-60% of the retail value so they can make a profit, while selling directly to other collectors on social media or auction sites might net you the full market price.
FAQ
Q: Does the 1986-S Washington Quarter contain silver?
A: No. In 1986, the standard San Francisco Proof Quarters were made of a copper-nickel clad composition (the same as regular change). The Mint did not start producing 90% silver proof quarters again until 1992.
Q: How many 1986-S Quarters were made?
A: The San Francisco Mint produced exactly 3,010,497 of these coins. Every single one of them was originally sold as part of the 1986 United States Proof Set.
Q: Why is my 1986-S quarter turning yellow or blue?
A: This is called “toning.” It happens when the metal reacts with oxygen or the chemicals in the storage container. Some collectors actually pay extra for beautiful “rainbow” toning, but heavy, ugly brown toning can decrease the value.
Q: Is a 1986-P or 1986-D quarter worth anything?
A: Generally, no. Unless they are in absolutely perfect “Mint State” (MS67 or higher) or have a major error, they are only worth 25 cents. However, a 1986-P in MS67 grade can be surprisingly valuable because few were saved in that condition.
