The Complete 2017 Quarter Value Guide

The FS-801 Doubled Die Reverse is the signature error of the 2017 America the Beautiful series. During die production at Philadelphia, the working die received multiple impressions from the hub at slightly different angles, embedding a doubled image directly into the die's surface. Every coin struck by that die carries the same doubling — making attribution consistent and confirmable.

Visual identification focuses on the two windows immediately to the right of the seated Douglass figure on the Cedar Hill house. Under a 10× loupe, collectors look for extra raised horizontal bars inside those window frames — the FS-801 diagnostic. Doubling can also appear in the reverse lettering. The critical distinction is that genuine hub doubling is rounded and three-dimensional, never the flat, shelf-like smear of worthless machine doubling.

Collectors pay a sharp premium because the FS-801 is a cataloged, attributable variety — it can be cross-referenced against CONECA and Wexler WDDR listings, making authentication straightforward. A certified MS68 example brought $576 at Heritage Auctions, and strong raw specimens with clearly visible doubling sell in the $20–$150+ range depending on eye appeal and grade.

The missing clad layer error is among the most visually dramatic mistakes that can occur on a modern U.S. quarter. During planchet preparation, the outer cupro-nickel layer — one of two that bond to the copper core to create the coin's characteristic silver-gray appearance — fails to adhere before the blank is fed into the coin press. The striking process then impresses the full design onto a planchet that is already missing one of its outer faces.

The result is immediately obvious: one entire side of the coin displays a bright reddish-orange or copper-brown color instead of the expected silver-gray. The affected side's design may appear slightly different in texture since it was struck directly against exposed copper. A diagnostic weight check confirms authenticity — a coin missing one outer nickel layer will weigh slightly less than the standard 5.670 grams, because the absent layer accounts for a measurable portion of total mass.

These errors command strong collector demand for two reasons: their dramatic visual impact and their relative rarity compared to die-related errors. A 2017-P Effigy Mounds example in MS65 grade sold for $200, while uncirculated specimens with full mint luster on the intact side fetch $125–$275. The rarest double-missing clad layer coins — where both outer layers are absent and the entire coin appears copper — have realized $300–$600 at auction.

An off-center strike occurs when the metal planchet is not correctly positioned inside the retaining collar as the dies come together. Instead of the blank sitting centered between the obverse and reverse dies, it has slipped to one side. The dies strike the full impression onto the mispositioned blank, but only part of the design lands on metal — the rest falls on empty space, leaving a plain crescent of unstruck metal on the opposite edge of the finished coin.

The diagnostic features are impossible to miss: the entire design cluster — Washington's portrait, lettering, and the reverse park imagery — is visibly pushed toward one side of the coin, while an arc of blank, featureless metal occupies the other side. Off-center examples exist across all five 2017 ATB designs. Value scales sharply with the severity of displacement: collectors measure the percentage of blank area to determine how far off-center the coin actually is.

Minor 5–10% examples sell for $15–$45 and are relatively common. The most prized specimens show 40–50% displacement where roughly half the coin is blank — yet the date numerals remain clearly readable on the struck portion. These dramatic pieces have realized over $200 at major online auction platforms. Preserving date visibility is critical: a coin with the date obscured or off the planchet is worth considerably less than one where the date is still legible.

Die cracks develop when the hardened steel working dies used at the U.S. Mint fracture under the enormous pressure of repeated striking. Every crack that forms in the die transfers to each subsequent coin struck as a raised, irregular line running across the coin's surface. When a fracture grows severe enough that a section of the die actually breaks away — typically near the rim — the void fills with metal during striking, creating a raised blob called a "cud" on the finished coin.

Both die cracks and cuds appear on all five 2017 ATB quarter designs. Die cracks present as raised, jagged lines that may cross lettering, cut through Washington's portrait, or traverse the open field areas of the reverse. The key diagnostic test: run a fingernail lightly across the suspicious line. A genuine die crack causes a slight snag because the metal is raised above the surface. Recessed lines are post-mint scratches with no collector value whatsoever.

Value within this category varies enormously. Minor die cracks add a modest $5–$30 premium depending on visibility and location. Significant cracks crossing major design elements like Washington's cheek or park-name lettering sell for $35–$90. Full rim cuds — where the break is severe enough to obliterate a section of the design near the edge — are far rarer, with documented examples selling for $100–$325 based on the cud's size, position on the coin, and overall grade.

A struck-through error occurs when a foreign object — anything from a piece of cloth or string to a fragment of debris or a spot of grease — becomes lodged between the die face and the planchet at the moment of striking. The die's full force drives the coin design into the metal everywhere except where the obstruction blocked contact. The result is a recessed or missing area on the finished coin that preserves the shape of whatever was caught in the press.

The obstructing material determines the specific appearance. Grease-filled die errors present as a blurry, undefined weak area where the design is present but mushy in detail — a common mint occurrence. Struck-through cloth or string errors create more distinctive linear patterns in the recessed area, with fiber texture sometimes visible under magnification. Struck-through debris can produce irregular voids of various shapes. For a genuine struck-through error to be confirmed, the impression of the foreign object must be clearly visible on either the obverse or reverse.

Values are directly tied to how dramatic and well-defined the obstruction impression is. Minor grease-filled strikes add only a few dollars of premium and are quite common across high-volume production runs. More unusual obstructions in prominent positions — crossing Washington's portrait or major reverse design elements — generate stronger collector interest. A 2017 George Rogers Clark quarter graded MS60 with a cloth struck-through error sold for $95 at a 2019 auction, demonstrating that even modest-grade examples find willing buyers.
