The 1988 Dime Value Guide: From 10¢ to $1,560

An off-center strike occurs when a planchet enters the striking chamber misaligned with the dies. Instead of being perfectly centered, the design is shifted toward one edge while an opposing crescent of blank planchet metal is left unstruck. The degree of misalignment — measured as a percentage of the coin's diameter — determines how dramatic, and how valuable, the error is.

To identify one, look for a noticeably blank wedge of plain metal on one side of the coin while the design appears crowded and near the opposite edge. The date must still be readable for maximum collector interest. A 1988-P with dual impressions — one at 65% off-center and a second at 95% off-center — sold for $376 in 2016. A more typical 1988-D at 45% off-center realized $89 in 2022.

Collector demand for off-center strikes is driven by visual drama and condition. Pieces shifted 20–50% with a fully visible date attract the broadest market. Those missing the date still sell, but at a discount. Sharp, uncirculated strikes with a visible date and 40%+ misalignment represent the top tier of this error class for the 1988 series.

A double strike error results when a coin is struck by the dies, ejects partially from the collar, and is then struck a second time before leaving the press. The second strike creates an overlapping ghost image of the design — two Roosevelts, two "LIBERTY" inscriptions, two sets of torch details layered on the same planchet. The greater the displacement between the two impressions, the more spectacular and valuable the coin.

Examine both the obverse and reverse for a secondary, partially complete impression offset from the primary design. Lettering will appear doubled along a curved or linear path. On a 1988-P, a second strike displaced 75% from the first created a dramatic overlapping composition that sold for $129.25 at a 2015 Heritage auction. Strongly displaced examples combining off-center elements with double striking can push into the $300–$400+ range.

Premium drivers are displacement degree, definition quality on both strikes, and overall surface preservation. The best examples show two largely complete, well-defined impressions with the date legible on at least one strike. Coins in Mint State condition — where both impressions retain original luster — command the top prices from advanced error collectors and major auction houses.

A broadstruck dime is produced when the collar die — the steel ring that contains the expanding planchet and imparts the reeded edge — is missing or retracted during the strike. Without the collar's restraint, the metal spreads outward under the striking pressure, creating a coin that is noticeably wider and thinner than normal but lacks a reeded edge. The design appears stretched toward the periphery and the edge is smooth rather than reeded.

Broadstrikes are identified by their oversized diameter (visibly wider than a normal dime), flattened profile, and smooth, unreeded edge. The design extends further toward the rim than normal, though the fields may look slightly shallow due to metal spreading. A 1988-P broadstrike graded MS-64 by PCGS has been documented in Heritage Auctions archives. Another 1988-P broadstrike example sold for $103.40 at a 2014 auction.

Value is heavily influenced by grade — broadstrikes in worn circulated condition sell for $30–$50, while Mint State examples in PCGS or NGC holders bring $75–$103 or more. Collectors prize clean, sharply struck broadstrikes where the design is fully defined despite the spread. Always authenticate broadstrikes with a grading service, as post-mint planing or filing can superficially mimic the smooth edge of a genuine broadstrike.

The 1988 Roosevelt dime is struck on a copper-nickel clad planchet — a copper core sandwiched between outer layers of 75% copper, 25% nickel. A missing clad layer error occurs when one of those outer nickel-copper facing layers is absent before striking. The result is a coin with one normal-looking silvery clad side and one side showing the reddish-brown copper interior of the core, or vice versa. This error originates in the planchet preparation stage before the blank ever reaches the press.

To identify a missing clad layer, examine both sides of the coin under good light. One face will appear reddish-copper in color with the design struck into the copper layer. The coin will also be noticeably lighter than a standard dime because of the missing nickel-copper cladding. Weigh the coin if possible — a normal 1988 dime weighs 2.27 grams, and a missing clad layer coin will typically be measurably lighter. The design is usually fully struck and legible.

Missing clad layer errors are among the rarest production mistakes on modern clad coinage and attract strong collector demand precisely because they are structural errors detectable before seeing a single die detail. Obverse missing clad examples (showing copper where Roosevelt's portrait should be) tend to command higher premiums than reverse examples due to their greater visual impact. Prices typically range $50–$200, with exceptional examples in Mint State condition going higher.

A clipped planchet error occurs at the blanking stage of coin production, when the die punch cuts circular discs from a continuous strip of metal. If the metal strip advances too quickly, the punch can overlap a hole already cut from a previous disc, slicing a curved or straight portion from the new blank before it is ever struck. The resulting planchet is missing a chunk of metal from its edge before it reaches the press — and this deformity is locked in permanently when the coin is struck.

Curved clips (the most common type) look like a smooth crescent of metal has been scooped from one edge of the coin. Straight clips have a flat cut edge. To authenticate a clip as genuine rather than post-mint damage, look for the Blakesley effect: a weakness in the design or rim directly opposite the clip, caused by insufficient metal flow during striking. If the rim and design are strong and complete on the side opposite the clip, the coin should be scrutinized more carefully as potential post-mint alteration.

Clipped planchet 1988 dimes are the most accessible and entry-level error coins in this series, typically valued at $20–$60 for circulated examples. Larger clips (missing more than 15% of the coin) and Mint State examples with the Blakesley effect clearly documented are the most desirable. Multiple clips on a single coin — rare but documented across clad coinage — push values significantly higher due to their increased rarity and visual impact.
