1938 Quarter Value: Everything You Need to Know

The Doubled Die Obverse occurs when a working die receives two or more impressions from the hub during the hubbing process with a slight rotational or lateral misalignment between strikes. Every coin produced from that affected die carries the doubled image permanently locked into the design, making this a true die variety rather than a random mechanical accident.

On 1938 quarters, examine the letters of "IN GOD WE TRUST" under a 10× loupe — particularly the second "T" in TRUST and the "E" in WE, which can display a noticeably doubled or split appearance. Washington's eye, the hairline above the ear, and the date digits may also show a thickening or secondary impression. True hub doubling displays consistent separation throughout, unlike machine doubling, which creates a flat shelf-like appearance with less collector value.

Strong, dramatic DDO examples are classified under the FS-101 designation by CONECA when confirmed, making them attributable and trackable in population reports. Collector premiums reflect both the visual drama of the doubling and the relative scarcity of confirmed examples in Mint State. Minor DDO coins add $50–$100 over base value; strong, clearly visible examples in MS grades have sold for $500–$2,000 or more at Heritage Auctions and Stack's Bowers depending on grade and doubling strength.

Before 1990, the U.S. Mint hand-punched mint marks directly into each working die individually, rather than incorporating them at the hub stage. This manual process meant that a die worker sometimes needed multiple strikes to achieve correct placement and depth, and occasional misalignment between the first and second punch left a permanent secondary impression in the die steel — creating a Repunched Mint Mark variety visible on every coin struck from that die.

On 1938-S quarters, look for a shadow, doubled edge, or partial secondary "S" impression near the primary mint mark position using a 10× loupe. Common RPM orientations include north, south, and diagonal positions where the second punch sits slightly offset from the first. An unusually thick "S" with irregular edges under magnification is often the first sign. Strong RPM varieties display clearly visible separation between the primary and secondary impressions, sometimes appearing as two distinct letters overlapping.

The RPM is specific to San Francisco-mint coins, making it a 1938-S-only variety and highly specific to that date-mint combination. Values range from approximately $25 for minor RPM examples in lower circulated grades to $500 or more for dramatic diagonal or sharp-angle RPM specimens in higher grades. Collectors prize these because they are fully attributable, traceable varieties rather than random damage or wear.

An off-center strike is a planchet error that occurs when the blank coin disc is not properly seated inside the collar before the obverse and reverse dies come together. With the planchet shifted to one side, the design is struck off-center — leaving a crescent-shaped area of unstruck, flat, blank metal on one side while the design crowds toward the opposite edge. The collar that normally constrains the coin into a perfect circle also fails to form completely, sometimes leaving an irregular outer edge.

Off-center strikes on 1938 quarters are genuinely uncommon because the striking process at both Philadelphia and San Francisco was tightly controlled during this era. When examining an off-center piece, note the percentage of displacement (measured as the proportion of the coin's diameter that is blank) and whether the date remains fully visible. Collectors value both factors heavily — a coin with 20–30% displacement but a complete, readable date is dramatically more desirable than the same displacement with the date missing.

Value depends almost entirely on the percentage off-center and the visibility of the date and design. A modest 10–15% displacement with full date visible typically brings $100–$300; a dramatic 25–50% off-center piece retaining a complete date can exceed $500 at major numismatic auction houses. Examples with missing or partially visible dates are worth considerably less to most collectors, though they can still carry premiums over regular circulated pieces for the novelty factor alone.

A strike-through grease error occurs when hardened or thickened die lubricant collects in the recessed design cavities of a die, forming an impenetrable barrier that prevents the soft planchet metal from flowing fully into those areas during the strike. The result is a coin with ghostly, partially missing, or unusually flat design elements in specific irregular areas — while surrounding details struck by unobstructed die steel remain sharp and fully formed.

The critical diagnostic feature that separates grease errors from simple wear is localization: grease errors affect random, irregular areas corresponding to where the lubricant accumulated, not the high-points that normal circulation wear affects uniformly. Look for absent or weakly formed letters in "LIBERTY" along the upper rim, flat or incomplete digits in the date, missing letters in "IN GOD WE TRUST," or soft eagle feathers on the reverse in irregular patches while adjacent feathers remain fully detailed.

Strike-through grease errors are underappreciated in the collecting community — they rarely receive the attention of RPM or DDO varieties, making them the "best kept secret" among 1938 quarter errors. Minor grease errors adding $20–$50 in premium are relatively findable in dealer stock; dramatic examples with entire motto letters missing or a largely blank eagle wing can reach $200–$500 for compelling, photographically dramatic pieces. Because these errors weren't widely catalogued at the time of striking, many circulate unrecognized, making careful examination worthwhile.
