The 2007 Roosevelt Dime Value Guide

An off-center strike occurs when the planchet fails to seat properly inside the collar before the dies descend, causing the design to be impressed onto a shifted blank. The result is a coin with a plain, blank crescent along one edge and the portrait or design elements pushed toward the opposite side. On 2007 Roosevelt dimes, the error can range from a barely noticeable 5% displacement to a dramatic 50%+ shift where Roosevelt's portrait hovers near the coin's edge.

Visual identification focuses on the blank crescent and the displacement percentage. Collectors pay the strongest premiums when the date "2007" remains fully legible despite the shift — a date-absent example has significantly lower desirability. Moderate displacements of 15–30% with a clear, visible date are the sweet spot for value. Extreme displacements above 40% that still show the date are among the most prized.

The 2007-P off-center example graded MS66 that realized $1,010 at Heritage Auctions in 2022 represents the benchmark for this error on gem-quality coins. Minor off-center examples (5–10%) with the date showing typically trade for $20–$68, mid-range examples (15–30%) for $30–$150, while the dramatic 50%+ pieces in high MS grades can far exceed $500 depending on strike sharpness, eye appeal, and certification.

A die cap forms when a freshly struck coin fails to eject from the press and instead adheres to the upper die face. As subsequent planchets are fed into the press, the trapped coin acts as a secondary die surface, striking an incuse mirror-image impression of its own design onto the incoming blanks — these secondary strike products are called brockage errors. The 2007 series produced documented examples of this dramatic error class.

Recognition centers on the distinctive incuse (sunken) mirror-image impression that appears on one face of the brockage coin. Unlike a normal design where relief elements are raised, a brockage impression shows the design pushed inward, with Roosevelt's portrait or the reverse torch appearing as a concave negative image. The original struck face retains normal relief. The die cap coin itself shows a progressively convex deformation as it absorbs subsequent strikes.

Heritage Auctions sold a 2007-D multi-struck die cap graded MS66 for $1,230 in 2020, one of the highest confirmed prices for any 2007 dime error. In November 2016, Heritage also sold a remarkable mated pair — a normal 2007-D Satin Finish SP68 alongside a Reverse Die Cap with Brockage graded SP67, both certified together in a PCGS double-wide holder documenting the complete error sequence. These mated pairs are the pinnacle of die cap collecting.

Rim cud errors occur when a section of the die's rim breaks completely away, leaving a void that fills with metal during each subsequent strike. The result is a raised, blob-like lump along the coin's circumference, replacing the normal flat rim and any design elements that once occupied that area. Shattered die errors, a related category, occur when the die develops severe internal fractures that transfer onto the coin's surface as a spiderweb of raised lines radiating outward from the impact zone.

On 2007 Roosevelt dimes, shattered die errors appear most dramatically on the reverse, where raised die-crack lines spread across the torch, olive branch, and oak branch like a metallic spider's web. Some examples show only one or two major cracks, while the most prized specimens display an intricate full-surface fracture network. A 2007-P variety with an interior die break plus a 50% retained cud — a compound die failure on a single coin — represents the extreme end of this error type.

Heritage Auctions sold a 2007-D dime with a rim cud error graded MS64 for $710 in 2022, demonstrating strong collector demand for dramatic die-failure errors on modern coins. A 2007-P with a shattered reverse die graded MS66 sold for $830 on eBay in 2022. Smaller cuds and minor cracks on ungraded examples trade for $75–$200, while large cuds covering a significant arc section near key design elements command the highest premiums.

A partial collar error, sometimes called a "railroad rim" error, occurs when the planchet only partially enters the retaining collar at the moment of striking. The collar normally constrains the expanding metal and imparts the reeded edge simultaneously. When the planchet sits partly outside the collar, the portion inside receives normal confinement and reeding, while the portion outside the collar expands freely, producing a distinctive stepped ledge around part of the coin's circumference.

The diagnostic feature is the step — a visible ledge partway up the coin's thickness on the partial-collar side, combined with a transition from normal reeding to a plain, flat edge. The struck face retains the full design normally, making the edge the primary diagnostic zone. Severity ranges from a barely noticeable partial reeding on a thin ledge to a dramatic coin where nearly half the edge is plain and the step is immediately obvious when the coin is turned edge-on in the hand.

These errors are systematically undervalued relative to their visual appeal, making them a "best kept secret" among modern error collectors. GreatCollections sold a 2007-P dime graded MS65 with a partial collar error for $645 in 2023, a strong price confirming collector appetite for gem-quality examples. Minor examples with thin ledges and partial reeding trade for $30–$75, while dramatic examples with clear stepped rims in Mint State grades command $200–$645+.

The wrong planchet error represents the most visually arresting mistake that can occur in the minting process — a planchet intended for one denomination entering the press chamber for a different denomination. The 2007-D Roosevelt Dime struck on a Lincoln cent planchet is the pinnacle example from this year: the standard dime design is impressed onto a smaller, distinctly copper-colored blank normally destined to become a one-cent coin, creating a coin that is visually and physically wrong in size, weight, color, and composition.

The diagnostic features are immediately obvious to any collector. A cent planchet measures approximately 19.05 mm in diameter and weighs 2.5 grams versus the dime's 17.9 mm and 2.27 grams — subtle dimensional differences, but the copper color is unmistakable. The Roosevelt portrait and the reverse torch appear normal in design but are struck on a distinctly reddish-brown or copper-colored surface instead of the standard silvery clad finish. When weighed on a precision scale, the discrepancy from a normal dime provides additional confirmation.

A certified example of this 2007-D dime-on-cent-planchet error sold at auction for $930, establishing the benchmark for this error type from this date. Wrong planchet errors are inherently rare because they require two independent failures: the wrong type of planchet must enter the correct press, then pass through the press without being caught by quality control. Each certified example is essentially unique in the specifics of its strike quality and planchet characteristics. Professional certification from PCGS or NGC is strongly recommended before selling.
