Curved Clip Error Coin




Curved Clip Mint Error Coin: 1978-D Penny

A curved clip mint error coin is a type of numismatic error that occurs during the production of coins. In other words, a 1978-D penny curved clip mint error refers to a portion of the coin’s circumference being absent. This is due to a misalignment during the blanking or cutting process.

1978 penny error

Furthermore, the blanking process involves cutting round metal discs, called planchets from large sheets of metal. Occasionally, the cutting machine may malfunction or experience misalignment. This results in irregularly shaped planchets.  Moreover, the irregularly shaped planchet used to strike a coin, creates a clipped mint error.




Note the Crescent-shaped Indention

Essentially, a curved clip mint error is named because a missing portion of the planchet creates a curved or crescent-shaped indentation. The location and size of the curved clip can vary, but typically affects a small segment of the coin’s circumference.

Note the Blakesley Effect

The Blakesley Effect refers to a specific type of error that can occur during the minting process of coins. It’s named after a man named Blakesley, who first described this phenomenon.

mint error coins to look for

The Blakesley Effect specifically refers to the raised rim formed along the clipped edge of a coin.  A coin struck with insufficient force or misalignment, displaces the metal pushing it upward.  This causes the formation of a ridge or rim along the clipped area and a flattened area opposite the clip.




Coin collectors find these errors intriguing due to their unique appearance and the circumstances during minting process.  List your own mint error discoveries on Ebay by observing how others have listed theirs.

2018 Michigan Quarter Errors

2018 Michigan Quarter Errors, Varieties, & Values

2018 Michigan quarter errors and varieties exist!  For instance, this 2018 Michigan quarter displays an improperly annealed planchet error.  Furthermore, I almost mistook it for an environmentally damaged coin.

pictured rocks error quarters

I learned otherwise after scouring the web for articles and visual examples and sought out advice for how to appropriately identify the error.  Moreover, to understand a mint error like this, it’s important to understand how the coin production process works.

The Annealing Process

 “Coins start out as blanks.  First, blanks are first cut from metal coils and then sent to an annealing furnace.  Then, from the furnace they go to a cooling water bath, followed by a polishing/brightening rinse.  Finally, drying machines help shine and burnish each piece.” – coinweek.com

The annealing process softens the metal to prepare it for striking.  Blank planchets are placed in an annealing furnace that first heats, and then slowly cools the metal.” – numismatics.

How to tell Environmental Damage from an Annealing Error

“To tell the difference between an annealing error, (which happens before striking,) and environmental damage, (which happens after striking), pay attention to the luster of the coin.

error quarters list 2018

Furthermore, the sheen on an uncirculated coin with an annealing error remains visible, whereas corrosion disfigures or destroys luster.” – ngccoin.com

Improperly Annealed Quarter Error

“The copper core (reeding) shows a nice normal red copper color.  Furthermore, the planchet displays as darker coloring remaining on the smooth edge of the reeding after the planchet is struck in the collar. 

2018-p michigan quarter error

However, when a coin is ejected from the collar, the darker coloring is removed from the ridged reeding.  The reeding as a normal red copper color is one of the key identifiers to know,” it’s legit.– Fred Weinberg – cointalk.com

Furthermore, the colors most associated with improperly annealed planchet errors are “copper, red, black, brown, and gray.  Coverage can be complete or incomplete.” – error-ref.com

Improperly Annealed Planchet Error Values

Improperly annealed planchet error values depends on a few factors.  They’ve sold between $5 and $20 in raw condition on Ebay.  This type of mint error can have asking prices higher than a hundred dollars, if it’s been properly authenticated.

A 2003 P Illinois State Quarter improperly annealed sintered planchet error, sold at auction via Great Collections for nearly $20.  A 2002 P Mississippi State Quarter Improperly Annealed Sintered Planchet, sold at auction via Great Collections for just $16.00.

pictured rocks quarter errors

The return of investment doesn’t appear worth sending a quarter with an annealing error in for grading.  Demand isn’t high for this type of error, so if you find one you’ll profit more by selling it in raw condition.

2018 Michigan Pictured Rocks Quarter Error

Examine pocket change carefully!  This camouflage colored 2018 P Michigan Pictured Rocks quarter with an improperly annealed planchet appears to be a dirty coin, but rather is actually a rare mint error.

The copper reeding on the coin wouldn’t be its natural color, and the quarter would be lacking its luster if it was just a normal dirty coin.  In other words, you have to look beyond the camouflage!

Furthermore, it’s known as “incomplete plating,” and “occurs when a zinc cent planchet is not fully coated with copper in the plating bath.   As a result, the zinc core remains exposed.” – CoinWorld

For instance, the partially unplated zinc planchet error shows how the copper plating didn’t completely cover the planchet, as seen in the images of this 2019 shield penny error.

“This type of plating error coincides with the introduction of copper-plated zinc cents in 1982.” 

“As with any denomination cent weights can vary, with some falling above or below the mean.”

It’s therefore possible to encounter a genuine unplated cent that matches or exceeds the weight of a normal cent.”  In other words, this coin weighed about average.  Furthermore, the zinc Lincoln cent coin is 97.5% zinc and 2.5% copper.

“The copper-plating operation of copper coated zinc planchets is done outside the Mint, by an outside supplier.  Partial and 100% unplated cents are much scarcer than many collectors realize.” – Fred Weinberg
