How to Identify the Harpers Ferry Quarter
A collector's walkthrough for confirming the 2016 Harpers Ferry Quarter: John Brown's Fort reverse, the West Virginia inscription, clad metal, and mint marks.

Start with the inscription. The fastest confirmation is the park side reading HARPERS FERRY and WEST VIRGINIA around a brick building, with the date 2016. That combination is unique to this America the Beautiful issue, so any quarter naming Harpers Ferry, West Virginia is the 2016 coin.
Read the reverse image to confirm the type. A genuine Harpers Ferry Quarter shows John Brown's Fort: a low, wide brick building with a small central cupola and arched openings, set on its grounds, with E PLURIBUS UNUM among the legends. This distinguishes it from every other ATB quarter, which shows a different park scene. If the building or state name does not match, you are looking at a different issue in the series. The obverse is the shared ATB Washington portrait, so identification always comes from the park side.
Verify size and metal. The coin is about 24.26 mm across with a reeded edge and weighs roughly 5.67 g. Examine the edge: a circulating copper-nickel clad quarter shows a coppery stripe sandwiched between silvery faces. A solid silvery edge with no copper stripe points to a silver proof collector strike rather than a circulation coin, and the large three-inch five-ounce silver piece is unmistakable by its size.
Locate the mint mark on the obverse, near the lower right of Washington's neck by the ponytail. P is Philadelphia, D is Denver, and S is a San Francisco proof or collector strike. For most Harpers Ferry Quarters authentication is unnecessary — they are abundant modern circulation coins. Reserve professional grading through a reputable service such as PCGS or NGC for high-grade uncirculated examples, confirmed silver pieces, or coins you suspect carry a genuine mint error, and be skeptical of ordinary coins promoted as rare simply for being an ATB design.
Frequently asked questions
How do I know it's the Harpers Ferry Quarter and not another park quarter?
Read the park side: it names HARPERS FERRY and WEST VIRGINIA and shows John Brown's Fort, a low brick building with a small cupola. Other ATB quarters name different sites and show different scenes.
How can I tell if mine is silver or clad?
Check the edge. A clad circulation coin shows a copper stripe and weighs about 5.67 g. A solid silvery edge indicates a silver proof, and the five-ounce silver coin is a much larger three-inch piece.
Where is the mint mark?
On the obverse, near Washington's ponytail at the lower right. P is Philadelphia, D is Denver, and S is a San Francisco proof or collector strike.
Are Harpers Ferry Quarters rare?
No. They were struck in large numbers for circulation in 2016 and remain common. Only silver proofs, top-grade uncirculated coins, and genuine errors carry a premium.
