Roosevelt dimes, first minted in 1946, have become a cornerstone of U.S. coinage. Beyond their face value of ten cents, some dimes boast rare errors or unique features that make them highly valuable to collectors. These minting mistakes can transform an ordinary coin into a prized collectible. Here’s a look at some of the most sought-after Roosevelt dime errors and their potential value.
1996-W Dime
To commemorate the Roosevelt dime’s 50th anniversary, the West Point Mint struck dimes with the “W” mint mark. These coins were included exclusively in Mint Sets, but some may have entered circulation.
Value: $10–$16 for common examples, with coins graded MS67 or higher reaching up to $45.
1982 No-Mintmark Dime
Dimes struck in 1982 at the Philadelphia Mint were accidentally issued without the “P” mint mark. Only about 75,000 of these rare coins exist, with strong-strike examples being particularly prized.
Value: Up to $2,185 for strong strikes in MS65 condition.
1965 Transitional Silver Dime
During the transition from silver to copper-nickel planchets in 1965, a few dimes were mistakenly struck on leftover 90% silver planchets from 1964. These transitional errors are exceptionally rare and highly sought after.
Value: These coins can fetch thousands of dollars depending on their condition.
1969-D Repunched Mint Mark
Some 1969 dimes minted in Denver display a repunched “D” mint mark due to a double-strike error. This also results in slight doubling of the inscription “IN GOD WE TRUST.”
Value: Well-preserved examples are worth around $100, with pristine specimens reaching up to $1,500.
1968-S No-Mintmark Proof Dime
A major error in 1968 resulted in San Francisco-minted proof dimes being issued without the “S” mint mark. With only a few dozen known examples, these coins are exceedingly rare.
Value: A PF67 version sold for $40,250 at auction in 2008.
1964-D Proof Dime
The 1964-D proof dime, the final 90% silver issue, was never officially released for circulation. Its rarity and deep cameo (DCAM) versions make it highly collectible.
Value: Standard proofs are valued at $525, with DCAM coins fetching as much as $4,600.
1999-D Broad Struck on Cent Planchet
This unusual error occurred when a dime design was struck on a cent planchet, resulting in a distorted coin with distinct coloring due to the mixed metals.
Value: One high-grade MS65 example sold for $10,000.
1998-P Bonded Cluster Error
A rare malfunction in the coining press resulted in approximately 32 dimes being fused together, forming a unique bonded cluster. Only one such error has ever been discovered.
Value: The sole example sold for $9,200.
1969-D Missing Clad Layer
Modern dimes are made with a copper core sandwiched between nickel-copper layers. Some 1969-D dimes were minted without one of these layers, exposing the copper core on one side.
Value: Typically valued at $50–$100, depending on the condition.
1970-S No-Mintmark Proof Dime
Following the 1968 error, another batch of San Francisco proof dimes in 1970 was issued without the “S” mint mark. With fewer than 500 examples known, these coins are highly desirable.
Value: A PF69 version sold for $1,610 in 2003.
Spotting Value in Small Change
Roosevelt dimes may be diminutive, but they hold immense potential for collectors. From mintmark errors to striking anomalies, these coins offer a glimpse into the fascinating world of minting mistakes. Whether you’re adding to your collection or looking to sell, these rare errors could bring a substantial return.
