The 2018-D Block Island National Wildlife Refuge Quarter is worth anywhere from 25 cents in circulated condition to $5 or more in uncirculated mint state, with top-grade specimens fetching $15 to $20 among collectors. If you just found one in your change or a drawer, you might be holding more than a quarter.
What Is the 2018-D Block Island Quarter?
The 2018-D Block Island National Wildlife Refuge Quarter is part of the America the Beautiful Quarters Program, a U.S. Mint series that ran from 2010 to 2021. Each year, five different national parks and historic sites were honored on the reverse of the quarter. Block Island National Wildlife Refuge, located off the coast of Rhode Island, was one of five sites featured in 2018. The “D” mint mark means the coin was struck at the Denver Mint.
This coin is a great starting point for anyone getting into coin collecting. If you’re not sure how to identify it or check its condition, using the best coin identifier app can save you a lot of time. Apps like these help everyday people figure out exactly which coin they have and what it might be worth before they do anything else.
The obverse (front) features the classic portrait of George Washington designed by John Flanagan. The reverse shows a piping plover bird perched on the beach with the Atlantic coast in the background — a design that many collectors find genuinely beautiful.
2018-D Block Island Quarter Value by Condition
The value of your 2018-D Block Island Quarter depends heavily on its condition. A coin that has been circulated — meaning it’s been used in everyday transactions — will show wear on the high points of the design. These are still worth face value or just slightly above.
However, coins that never entered circulation and still have their original mint luster are called uncirculated or mint state coins. These are the ones collectors are most interested in. The CoinHix app makes it easy to look up current prices based on grade, so you don’t have to guess.
Here’s a general value breakdown:
| Condition | Grade | Estimated Value |
|---|---|---|
| Circulated (worn) | G to EF | $0.25 – $0.50 |
| About Uncirculated | AU-55 to AU-58 | $1 – $2 |
| Mint State | MS-63 to MS-65 | $3 – $8 |
| Gem Mint State | MS-66 to MS-67 | $10 – $20+ |
How Mintage Numbers Affect the 2018-D Block Island Quarter Value
The Denver Mint produced approximately 99.4 million 2018-D Block Island Quarters. That’s a fairly large mintage, which is one reason most circulated examples are only worth face value. With hundreds of millions of coins produced, there’s simply no shortage in the market.
That said, high-grade examples in MS-67 or better are genuinely scarce. Not every coin comes out of the mint in perfect condition, and even fewer survive without any contact marks or bag scratches. If you have a coin that looks absolutely flawless under good lighting, it could be worth getting it professionally graded.

Should You Get Your 2018-D Block Island Quarter Graded?
If your coin looks brand new — no scratches, no discoloration, full luster — you might be wondering if it’s worth submitting to a third-party grading service like PCGS or NGC. Professional grading typically costs $20 to $40 per coin for standard service, so it only makes financial sense if your coin grades MS-66 or higher.
For most people who found a 2018-D Block Island Quarter in their pocket change, professional grading probably isn’t necessary. But if you pulled it from a mint roll and it looks pristine, it’s worth a closer look.

Tips for Finding Value in Your Coin Collection
Finding an old or interesting coin doesn’t have to be overwhelming. Here are a few quick tips:
– Check the mint mark first. The “D” means Denver. A “P” means Philadelphia, and an “S” means San Francisco (usually proof coins).
– Look at the coin under good light. Luster, contact marks, and sharpness of detail all affect grade.
– Don’t clean your coins. Cleaning almost always reduces value.
– Use a reliable app. CoinHix helps you look up coins quickly and accurately without needing to be an expert.
