The 2018-S Apostle Islands Quarter is worth anywhere from $1.50 in circulated condition to over $10 or more in pristine proof grades — and some high-grade examples have fetched even higher prices among serious collectors. If you stumbled across one of these coins in your change jar or an old collection, you’re in the right place to find out exactly what it’s worth.
What Is the 2018-S Apostle Islands Quarter?
The 2018-S Apostle Islands National Lakeshore Quarter is part of the America the Beautiful Quarters Program, which ran from 2010 to 2021. Each year, the U.S. Mint released five different quarter designs honoring national parks and historic sites across the country. The “S” mintmark on this coin means it was struck at the San Francisco Mint — and that’s a big deal.
San Francisco didn’t produce quarters for general circulation. Instead, the “S” mint coins were made exclusively as proof coins, sold directly to collectors in special sets. That means if you have an 2018-S Apostle Islands Quarter, it didn’t come from your pocket change — it came from a proof set, making it a bit more special than the everyday quarter.
If you’re not sure whether your coin is a proof or just a regular strike, a free coin identifier app can help you figure it out quickly using just your phone’s camera. Apps like CoinHix are especially popular for this kind of instant identification.
How Much Is the 2018-S Apostle Islands Quarter Worth Today
Here’s where things get interesting. Because the 2018-S Apostle Islands Quarter is a proof coin, its value depends heavily on grade and whether it’s been certified by a professional grading service like PCGS or NGC.
In raw (uncertified) condition, a typical proof example is worth around $3 to $6. But if the coin grades PR-69 or PR-70 (the top of the proof scale), values can jump significantly. A PR-70 Deep Cameo example can sometimes sell for $15 to $30 or more, depending on demand.

| Grade / Condition | Estimated Value |
|---|---|
| PR-65 (Proof, typical) | $2.00 – $4.00 |
| PR-67 Deep Cameo | $4.00 – $8.00 |
| PR-69 Deep Cameo | $8.00 – $15.00 |
| PR-70 Deep Cameo (perfect) | $15.00 – $35.00+ |
| Uncertified / Raw Proof | $1.50 – $6.00 |
Mintage Numbers and Why They Matter
The 2018-S Apostle Islands Quarter had a mintage of approximately 424,000 coins — relatively low compared to the hundreds of millions of “P” and “D” mint quarters struck for circulation. Low mintage generally means better long-term collectibility, as there are simply fewer coins out there for collectors to chase.
That said, low mintage alone doesn’t make a coin valuable overnight. Most people who bought proof sets in 2018 kept them in good shape, so the supply of high-quality examples is fairly steady.
Still, compared to a random quarter pulled from a cash register, the 2018-S is in a completely different league in terms of craftsmanship and collectibility. The sharp details, mirror-like fields, and frosted design elements make proof coins a pleasure to look at even if you’re not a hardcore numismatist.
For a broader look at what 2018 quarters are worth across all mint marks and varieties, it’s worth reviewing multiple sources to get the full picture.
How to Tell If Your Coin Is Valuable
First, check the mintmark. Flip the coin over and look just to the right of “IN GOD WE TRUST” near Washington’s portrait. If you see a small “S,” you’ve got the San Francisco proof version.
Next, examine the surface. Proof coins have two distinct visual characteristics: a mirror-like background (called the “field”) and a frosted, almost matte finish on the raised design elements. This contrast is called “cameo” or “deep cameo,” and coins with strong cameo contrast are the most desirable to collectors.
Finally, consider getting it graded. If your coin looks flawless with no visible marks or fingerprints, it might be worth submitting to PCGS or NGC. A certified PR-70 Deep Cameo can command several times the value of an ungraded coin. CoinHix also lets you track certified coin prices over time, so you know the best moment to sell.
Should You Hold On to It or Sell?
Honestly, if you have a complete 2018 proof set in its original box, it’s probably worth more as a set than broken apart. Full sets with the original packaging and certificate of authenticity tend to sell for $25 to $40 on platforms like eBay, which is a solid return compared to face value.
If you have a single coin without packaging, you can still get a few dollars above face value — especially if it’s in excellent proof condition. Coin shows, local dealers, and online marketplaces are all reasonable options. Use CoinHix to scan recent sale prices before listing so you don’t leave money on the table.
FAQ
Q: Is the 2018-S Apostle Islands Quarter rare?

Q: Can I find a 2018-S Apostle Islands Quarter in everyday change?
A: No. The “S” mint proof quarters were never released into general circulation. They were sold only in proof sets directly from the U.S. Mint, so finding one in pocket change is essentially impossible.
