The “Football-Shaped” Gold Eagle: A Unique U.S. Mint Error
A unique 2023 $5 Gold Eagle mint error shows how one tiny failure in the blanking process created one of the most dramatic modern U.S. gold errors known.
A modern U.S. gold coin should not look like this.
The U.S. Mint strikes the $5 American Gold Eagle on a round, carefully prepared planchet. The normal one-tenth-ounce Gold Eagle carries a $5 face value, measures 16.50 mm, contains 0.1000 troy ounce of gold, and weighs 3.393 grams.
Yet this 2023 $5 Gold Eagle weighs only 3 grams. More importantly, it did not leave the press round. It left as a football-shaped gold coin with missing design, missing edge detail, and a mint-made error story that few U.S. gold coins can match.
According to Mike Byers of Mint Error News, this piece ranks as the only known U.S. gold coin of any denomination struck on an elliptical planchet.
What Is an Elliptical Planchet?
An elliptical planchet starts with a problem before the coin ever reaches the dies.
During normal production, a blanking press punches round blanks from a metal strip. However, if that strip fails to advance correctly, the punch can overlap a previously cut area. In some cases, the mistake creates two pieces: an oval, or elliptical, blank and a crescent-shaped clipped blank. Error-Ref describes elliptical clips as one of the most desirable forms of incomplete planchets. The finished coin often takes an oval shape.
That matters here because gold mint errors rarely escape the system. Also, elliptical planchet errors usually lose much of their original shape during striking. The collar and the pressure of the dies push metal outward. As a result, many examples look less dramatic after the strike.
This coin took a different path.
Why This Gold Eagle Still Looks Like a Football
The drama comes from the shape.
Byers notes that an elliptical planchet often expands in the collar and loses much of its “football shape.” However, this 2023 $5 Gold Eagle retained that unusual outline. The result gives collectors an instant visual clue. This coin does not need a microscope to explain itself.
The missing metal also changed the design. The coin lacks part of the stars and edge from about 7 o’clock to 11 o’clock. In addition, mechanical doubling shows clearly because the planchet did not sit properly in the collar during the strike.
That combination creates the “wow” factor. The coin does not simply carry a technical label. It shows the error at a glance.
The Weight Tells the Story
The weight confirms the missing metal.
A standard one-tenth-ounce American Gold Eagle weighs 3.393 grams. This coin weighs 3 grams, according to the NGC label. That means it lost about 0.393 grams, or roughly 11.6% of its normal gross weight.
That missing gold explains the incomplete design. It also explains why the coin looks so different from a normal 2023 $5 Gold Eagle.
However, the weight alone does not create the excitement. Many error coins show missing metal. This coin does something far rarer. It combines missing gold, an oval planchet, a modern American Gold Eagle design, and a Mint State 69 grade on an NGC-certified holder.
Why Gold Errors Matter
Collectors treat U.S. gold mint errors differently because they survive in such small numbers.
Gold coins move through stricter handling and tighter controls than base-metal circulation coins. Also, modern bullion and collector gold issues carry intrinsic value from the moment they leave production. That makes major errors especially difficult to encounter.
Byers places this discovery in the company of other major U.S. gold errors he has handled. His list includes three gold Indian Head cent errors, the unique gold Buffalo nickel, the unique $20 Liberty struck on a large cent blank, plus gold off-centers, double strikes, and brockages.
That background matters. It shows why this coin does not stand out only because it looks strange. It stands out because it enters a narrow field of elite U.S. gold mint errors.
A World Gold Comparison
Byers also reports that he knows of only one non-U.S. gold coin struck on an elliptical planchet: a Great Britain gold sovereign that he handled more than 20 years ago. Mint Error News illustrates that British piece as a comparison.
That comparison gives the U.S. Gold Eagle even more weight. Elliptical planchet errors appear in many coin series. However, gold examples sit in a different class.
Therefore, this 2023 $5 Gold Eagle does not just represent a modern mint mistake. It represents a rare collision of planchet-production failure, precious-metal coinage, and striking-room survival.
A Mint Error With Immediate Visual Appeal
Some great errors need long explanations. This one does not.
The oval shape, missing edge, missing stars, and off-balance strike tell the story before the label does. Then the label adds the final layer: 2023 Eagle G$5, Mint Error MS69, Elliptical Planchet, 3g.
That is why this coin fits two different collecting worlds. Error specialists can view it as a unique major mint error. Gold collectors can view it as an extraordinary outlier in the American Gold Eagle series.
Either way, the backstory drives the appeal. A gold strip failed to move the way it should. A blanking press created the wrong shape. Then the dies struck that wrong shape into a legal-tender U.S. gold coin.
Most of the time, that chain of events ends inside the Mint. This time, it created a modern U.S. gold rarity.
Why Collectors Will Remember This Coin
The best mint errors do more than break the rules. They reveal the rules.
This 2023 $5 Gold Eagle shows how planchets begin as metal strip. It shows how blanking mistakes happen. It also shows how the collar shapes metal during the strike. Finally, it shows how one small production failure can create a numismatic object with outsized importance.
Byers calls the piece an exciting new discovery and a unique gold mint error. That description fits. The coin combines rarity, instant visual appeal, precious metal, and a story that collectors can understand in seconds.
For a modern U.S. gold coin, that is a powerful combination.
