The 1952 Roosevelt Dime Value Guide

Before modern hub technology, individual mint marks were hand-punched into each working die — sometimes more than once, at a slightly different angle or position. The FS-501 variety on the 1952-S dime occurred when the "S" punch was applied twice, leaving a secondary impression below and to the south of the primary mint mark. This variety was cataloged as FS-501 in the Cherrypickers' Guide to Rare Die Varieties and is the single most significant attributable die variety for the entire 1952 Roosevelt dime issue.

Visually, the secondary "S" appears as a ghost or shadow impression just below the primary mint mark. Under a 5–10× loupe, you can clearly distinguish the letterform of the offset punch. The secondary impression is generally complete enough to see the curved arms of the S, not merely a die scratch or grease fill, which makes attribution straightforward compared to more subtle RPMs.

Collector demand is strong because FS-501 is the only RPM on 1952 dimes that receives consistent premium pricing from PCGS and NGC-certified examples. Uncirculated specimens (MS63–MS65) typically bring $60–$200, with top-grade pieces pushing into the $300+ range. The variety commands 5× to 15× the value of a plain 1952-S in equivalent grades.

A doubled die obverse error occurs when the working die receives multiple impressions from the hub during the hubbing process, with a slight rotational or lateral shift between each impression. On the 1952 Roosevelt dime, this results in clearly visible doubling on the obverse elements — most notably the lettering in "LIBERTY," the date numerals, or Roosevelt's portrait details such as the ear or hairline. The error originates entirely at the die, not the planchet, so every coin struck from that die shares the same doubling.

Under a 10× loupe, a genuine DDO shows distinct, clearly separated doubling — two distinct impressions of a letter or number edge — rather than the "machine doubling" or shelf doubling that appears as a flat, shelf-like distortion on high points. Machine doubling has no collector premium; true hub doubling does. Focus on letters in "LIBERTY" or the digit edges of the date for the clearest diagnostic features.

The premium a DDO commands depends heavily on the severity of the doubling. Minor DDOs with subtle separation may add $40–$75 to the coin's base value. More dramatic examples with clear, clean doubling visible to the naked eye or with low magnification can bring $100–$200 or more in circulated grades, with uncirculated examples proportionally higher. Submit candidates to PCGS or NGC for attribution before selling.

An off-center strike occurs when a planchet is not properly centered under the dies at the moment of striking. The result is a coin where the design is shifted to one side, leaving a blank, unstruck crescent of metal on the opposite side where the dies made no contact. The coining collar, which normally shapes the edge, is not engaged on the blank side, so that portion of the edge is plain rather than reeded. Off-center strikes on 1952 Roosevelt dimes are uncommon planchet handling errors that slipped through quality control at the mint.

The most important diagnostic factor — beyond the obvious misaligned design — is whether the date remains fully legible. Collectors strongly prefer off-center strikes where "1952" is complete, because undated off-center strikes are hard to attribute to a specific year. The percentage off-center also matters: a 10–20% shift with the full date visible is worth $15–$40, while a dramatic 40–60% off-center example with date intact can bring $75–$150 or more.

For maximum value, look for examples with a clearly visible date, a full design impression on the struck portion, and a clean, unstruck crescent on the blank side. The more dramatic and visually striking the error, the stronger the collector interest. Eye appeal — including coin grade on the struck portion — adds meaningful premium at any off-center percentage.

A clipped planchet error happens before the coin is ever struck. During the blanking process, a circular disc (planchet) is punched from a long strip of metal. If the punch overlaps a hole left by a previously punched planchet, the resulting blank has a curved or straight section missing from its circumference — the "clip." When that defective blank then gets struck by the dies, the finished coin carries the clip through to the final product, resulting in a coin with a concave or straight bite visibly missing from one area of the rim.

Curved clips (the most common type) follow the arc of the punching tool, giving the missing section a smooth, rounded profile. Straight clips are less common and occur when the strip end was used. The affected area typically shows weakness in the nearby design elements — letters or numerals near the clip are often flat or incompletely struck because metal flow was disrupted by the missing material. This is known as the "Blakesley Effect" and helps authenticate genuine clips versus post-mint damage.

Collector interest in clipped planchets is steady but modest. Values range from $20–$40 for small, subtle clips to $50–$75 for dramatic examples where more than 10–15% of the coin's mass is missing and the Blakesley Effect is clearly observable. Clips that are large, symmetrical, and on a relatively clean coin command the top of the range.

Die cuds and die cracks are late-die-state errors caused by metal fatigue in the coining die itself. A die crack is a hairline fracture that appears as a raised line on the coin's surface, running from one design element to another. A die cud is a more severe version: when a piece of the die actually breaks away at the rim, that missing section causes a raised, blob-like area of flat metal on the coin's surface — typically at or near the rim — because the broken portion of the die cannot sink metal the way the intact die can. Both errors worsen as the die continues to be used.

On 1952 Roosevelt dimes, die cracks most often run through the obverse fields or through Roosevelt's portrait. Minor hairline cracks add minimal value ($5–$15), but dramatic cracks crossing multiple design elements or connecting two rim points are significantly more desirable. Die cuds — the blob-at-the-rim version — are rarer and command higher premiums because they represent actual die failure rather than early cracking.

A genuine die cud will appear as a raised, featureless blob of metal flush with or slightly above the coin's rim, with no design detail in that area. The adjacent design elements (letters, portrait) may show progressive weakness as you approach the cud. Values depend on cud size and position: rim cuds on the obverse involving "LIBERTY" or the date command stronger premiums, ranging from $50–$100 or more for dramatic examples on otherwise clean coins.
