2007 Half Dollar Error List with Pictures
A 1972-D half dollar missing the designer’s FG initials sold for $900 in 2022. That recognized older variety offers a comparison, but it does not prove the same error on a 2007 coin.
Reports of 2007 half dollar errors include extra raised marks, missing metal, and weak lettering. Estimated values below run from $5 to $700 when the proposed mint error is confirmed.
Read on to see what each claim means and which visible clues can support it.
1. 2007 Kennedy Half Dollar Die-Crack and Chip Candidates (Estimated Up to $75)
A thin raised line or small raised lump can come from a damaged die, the steel tool that stamps coins. A crack in that tool fills with metal during stamping.
The result is a line standing above the coin’s surface. A small piece breaking from the tool can instead leave a compact raised lump.
A general 2007 guide describes these possibilities but does not identify a dated example. Its eye-related nickname does not establish an error at Kennedy’s eyes.
Check the date on the coin itself. A discussion posted in 2007 may actually concern a much older half dollar.
Estimated Value
Estimate $5–$75 for a genuine small crack or chip on an ordinary collectible 2007 half. Faint lines usually sit near the lower end.
This is an estimate for a confirmed example, not a recorded 2007 sale. A more obvious 1998-D triple clip graded MS63 sold for $99 in March 2025.
That older coin had missing pieces, not a crack. Its sale only helps put the modest estimate in perspective.
How to Identify
Take one photograph showing the date, mintmark, and unusual mark together. This prevents an older coin from being mistaken for a 2007 example.
The regular layered-metal coin weighs 11.34 grams. An S Proof, specially made for collectors, can instead contain 90% silver and weigh 12.50 grams.
Both measure about 30.6 millimeters and have edge grooves. Use a scale and calipers when safely accessible, then inspect the mark through a 10× magnifier.
Move the light to show its height without scraping anything. A scratch usually cuts downward; look for a line or compact lump rising from the original stamped surface, rather than dirt resting on it.
2. 2007 Kennedy Half Dollar Rotated-Die Candidate (Estimated Up to $250)
The eagle can lean to one side when the front and back pictures are out of alignment. A stamping tool may have turned in its mounting.
The 2007 guide discusses this possibility using a later coin as its example. It does not identify a measured rotation on one specific 2007 half.
Photographs alone can mislead. A seller may straighten each face separately, or a camera may be tilted.
Test the coin with a controlled turn from top to bottom. The normal result is an upright eagle, not an upside-down one, when Kennedy starts upright.
Estimated Value
A confirmed, obvious rotation is estimated at $40–$250 on a collectible 2007 half. A tiny tilt usually attracts less interest than a large turn.
A 2000-P graded PCGS MS61 sold for $79 in March 2025. Its back was rotated 75 degrees clockwise.
That is a different-year sale with a measured angle. It does not establish either that angle or a grading-service identification for a 2007 candidate.
How to Identify
Hold Kennedy upright and turn the coin from top to bottom without twisting your fingers. Film several turns, then measure how far the eagle leans from upright.
A left-to-right turn gives a different result. Keep the same turning direction throughout the test.
Check the edge through a magnifier for seams that might reveal two joined coins. Calipers should show about 30.6 millimeters across, with grooves around the edge.
When safely accessible, use a scale against 11.34 grams for the layered-metal issue or 12.50 grams for the silver Proof. Repeat the controlled top-to-bottom turn: the eagle should lean by the same amount each time.
3. 2007-D Kennedy Half Dollar Reported Clipped Planchet (Estimated Up to $300)
Metal can be missing before the coin receives its picture. This is a clipped planchet; planchet means the blank metal disc.
The Denver year listing reports clips without saying whether the missing area is curved, straight, or irregular. No one shape can be assigned to every reported 2007-D.
The cutting punch may overlap an earlier hole or the edge of the metal strip. That leaves an incomplete disc for the coin press.
A later strike forms the design around the gap. Cutting or filing a finished half also removes metal, but leaves different marks where the gap meets the picture.
Estimated Value
Estimate $50–$300 for modest to obvious clips on collectible unworn examples. A clear original gap and attractive surfaces support the stronger end.
A 1998-D with three clips totaling ten percent sold for $99 in March 2025. PCGS graded that older coin MS63.
The sale is a comparison, not a description of the reported 2007-D. Its three-gap arrangement should not be copied onto a 2007 coin whose actual outline has not been shown.
How to Identify
Compare with a normal 2007-D at the same size. Follow the border on each side of the missing section through a 10× magnifier.
Did the design form beside an existing gap, or does a sharp cut slice through finished details? File marks, sharp burrs, and freshly sheared metal suggest later damage.
The normal coin weighs 11.34 grams and measures about 30.6 millimeters, with edge grooves. Use a scale and calipers across the intact areas when safely accessible.
A weak rim opposite the gap can help, but is not required on every clip. Look for silver-colored outer metal spreading naturally toward the gap without tool marks cutting through it.
4. 2007-D Kennedy Half Dollar Reported Doubled Die (Estimated Up to $350)
Extra raised outlines can repeat on coins made by the same stamping tool. The tool received a doubled design before it began making coins.
CoinTrackers lists doubled dies for 2007-D, but does not name a specific variety or affected face. The report therefore does not establish one particular doubled letter or ear.
The general year guide suggests checking LIBERTY and IN GOD WE TRUST. These are places to look, not confirmed marks of a named 2007-D variety.
A candidate needs its own matching pattern. Mere thickness or a reflected outline does not prove that the tool’s design was doubled.
Estimated Value
Estimate $60–$350 for a clearly identified unworn 2007-D with raised, separated doubling. A bold pattern is easier to show than a very faint one.
The year guide places modern examples around $60 and upward. That is guide advice, not a completed sale.
The upper figure is an estimate for a stronger, clearly matched feature. Flat shelves caused by movement during stamping do not qualify for the same doubled-tool price range.
How to Identify
Separate normal circulation coins from satin mint-set coins, whose softer surface finish is intentional. Both Denver versions weigh 11.34 grams and measure about 30.6 millimeters.
Check those measurements with a scale and calipers when safely accessible, and inspect the edge grooves. Then examine both faces through a 10× magnifier.
A flat shelf that reduces a letter’s outline can come from movement during stamping. Worn tools can also leave ragged-looking letters.
Look for rounded extra edges, then compare another coin of the same proposed variety. The useful check is the same extra outline in the same place on more than one coin, rather than one thick-looking letter.
5. 2007 Kennedy Half Dollar Missing-FG Candidate (Estimated Up to $400)
The small letters FG are designer Frank Gasparro’s initials. On the back, glare can hide them between the eagle’s tail and the leg on your right.
On some recognized older varieties, polishing the stamping tool removed these shallow initials. Wear, trapped material, or deliberate smoothing can also hide them on a coin.
The 2007 guide illustrates its discussion with other years, including 1966 and 1972-D. It does not document a matching 2007 example.
A smooth-looking space therefore needs a closer look. Both letters must truly be absent, and the cause must fit minting rather than later damage.
Estimated Value
Estimate $75–$400 only after complete mint-made loss of the initials is confirmed on a collectible 2007 coin. Faint letters and later polishing do not meet that condition.
A recognized 1972-D No FG FS-901 graded NGC MS64 sold for $900 in December 2022. That older variety shows collector interest.
It is not a documented 2007 price. The famous name should not turn barely visible initials into completely missing ones.
How to Identify
Move the light before increasing magnification. A shallow F or G may appear as soon as the bright reflection moves away.
Use a 5× to 10× magnifier between the tail and the leg on your right. Check nearby feathers and the leg for scraping, polishing lines, or unusual weakness.
When safely accessible, compare scale readings with 11.34 grams for a layered-metal half or 12.50 grams for a silver Proof. Both should measure about 30.6 millimeters with calipers and have edge grooves.
Another matching coin can help show that the stamping tool caused the loss. First look for any surviving piece of either letter: even a faint fragment means FG is not completely absent.
6. 2007-S Kennedy Half Dollar E-Area Strike-Through Candidate (Estimated Up to $500)
The E in AMERICA looked unusual on half dollars from two 2007 Proof sets. A collector reported the matching area, but did not establish its cause.
An object between the blank and stamping tool could leave an impression. Scratching, contact with packaging, or damage to the tool itself could also change a letter’s appearance.
The two-set observation is useful to compare, not enough to choose between those explanations. Each mark still needs a clear close-up.
The report does not state the metal. These S-mint collector coins could be silver or layered-metal Proofs; the set reference alone does not decide.
Estimated Value
Estimate $75–$500 for a small confirmed strike-through on a well-preserved Proof. The upper end needs a distinct impression and attractive surrounding surfaces.
A 1992-D circulation coin struck through a small edge-groove fragment sold for $336 in 2021. NGC graded that different coin MS64.
The recognizable object impression makes it a useful comparison. It does not identify the cause of the two E marks or give either 2007 Proof a sale price.
How to Identify
Compare photographs of both E marks under the same lighting. Identical shapes could come from a lasting tool defect, so repetition does not by itself prove a loose object.
Check the original packaging or grading label for the metal type. A layered-metal Proof normally weighs 11.34 grams; a 90% silver Proof weighs 12.50 grams.
Both measure about 30.6 millimeters and have edge grooves. Use a scale and calipers only when safely accessible, keeping sealed holders closed.
View the E through a 10× magnifier without touching the shiny surface. Tilt the light to see whether the mark sinks into the letter, rises above it, or only changes its shine.
7. 2007-D Kennedy Half Dollar Reported Missing Clad Layer (Estimated Up to $700)
A copper-colored patch may appear where part of the outer layer is missing. The 2007-D listing reports both partial and more complete layer loss.
A normal Denver half has copper-nickel outer layers bonded to a copper middle. A failed bond can expose that middle and leave a visible step beside the surviving layer.
The report does not name the affected face, size of the patch, or weight. Those details require the actual coin.
Brown staining can look similar without any missing metal. The 90% silver S Proof has different construction, so this Denver explanation should not be applied to it.
Estimated Value
Estimate $125–$700 for an unworn 2007-D with confirmed original layer loss. A large readable area may interest collectors more than a tiny patch.
A 1998-P NGC MS63 with defective front cladding sold for $149 in March 2023. A separate 1998 ANACS MS64 partial-loss coin was offered for $349.97.
The first amount is a sale and the second an asking price. Neither establishes the exact appearance or value of a reported 2007 example.
How to Identify
A copper stripe around the edge is normal on this coin. It is the middle layer showing between the two outer layers, not automatically an error.
For a suspected missing face layer, weigh the coin against the normal 11.34 grams. Calipers should be compared with about 30.6 millimeters across.
Use a 10× magnifier to inspect the edge grooves, opposite face, and copper-colored patch. Grinding, chemical stripping, or added plating can change the surface after minting.
Color alone is not enough. Follow the border of the patch and look for a physical step between exposed copper and the intact outer layer, rather than a flat change in staining.
Conclusion
For a 2007 half dollar, start with the visible mark rather than an appealing error name. Check whether it rises, sinks, or removes actual metal, then compare the correct finish and alloy.
The estimates range from $5 to $700 for confirmed mint errors. A satin surface can be normal, faint FG can still be present, and a copper stripe around the edge is part of an ordinary layered-metal coin.
