Mint Errors

It will be obvious, to the experienced mint error-variety collector, that many of the coins pictured below are considered varieties and not mint errors. However, this author classifies any coin that makes it into collectors hands, with an “alteration” (accidental or purposeful) in their design, planchet, metal content or any other various deviation from the original and intended state of the coin, by or at the US Mint, as a “Minting Variety”.

Capped Die  (Mushroom / Bottle Cap)  Mint Errors 

A slightly crescent clipped planchet and the force of the strike managed to split the copper clad layer, revealing the zinc planchet underneath.

A Lincoln Memorial Cent struck with a Roosevelt Dime Die. It called a “Mule” because one side is struck with a different coin die. So what do you call it a one cent, a dime or an eleven cent piece?

Cent Struck On A Dime Planchet Stock

2000-P Lincoln Memorial Cent struck on a 2000 Roosevelt Dime Planchet, and a Die Clash. The coin is not silver but copper-nickel clad.

1999 Lincoln Cent Broadstrike mint error. This example is almost perfectly centered, but there are some that are off-center. However, and Broadstrike coin that’s more than 10% off-center is considered an Off-Center struck coin.

Repunched Mint Mark “RPM”

1960-D Lincoln Memorial Cent Re-punched Mint Mark, commonly called an RPM.

1984 Lincoln Memorial Cent with a Die Clash. This occurs when an obverse die strikes the reverse die (without a coin between them), and some of the design of the opposite die is struck on both dies. Then a planchet is struck showing design elements on each side of both dies.

Minor Die Clash

2000 Sacagawea Dollar wounded eagle.

1917 and 1946 Lincoln Wheat Cents with lamination peels and cracks.

Doubled Die Varieties

All of the above are true double die mint errors, and not to be confused the “Poor Man’s” double dies which are not true double dies, but abraded dies or from worn dies. It’s also not a double struck coin either. A true double die happens after the engraving lathe accidentally carves a double image on the master hub that is transferred to the

die. If the second image appear flat or shelf-like then it’s not a double die.

1943 Lincoln Wheat steel cent struck in collar error.

1967 Lincoln Memorial cent with multiple strikes.

2007-P James Madison Double Struck Presidential Dollar. A new discovery.

Pattern Design

2000-P Sacagawea Dollars. The left picture is an accented hair, pattern, Cheerios Dollar, and the right picture is a normal tail feather. Recently PCGS discovered that not all Cheerios Dollars are patterns.

Missing Clad Layer

Roosevelt Dime missing the clad layer on the reverse.

Roosevelt Dime Off-Center Strike (no date). This coin is struck around 50% off-center with most of the date showing. The most sought after are coins showing full date, and coins can be off-center anywhere from 1% and up.

Struck With Cracked Die

1794 Flowing Hair Half Dime with die cracks. Modern coins with die cracks don’t bring extra value, unless it affects the design dramatically. However, in older type coins it can signal a possible variety and bring a premium.

Wide Rim Variety

1979-P “Near Date” Susan B. Anthony Dollar (left) with a normal rim dollar (right). You tell the “Near Date” by the thick rim that causes the date to be nearer to the rim. It is actually a variety, not an error.

Minor Double Die

2005-D Minnesota Statehood Quarter Extra Tree Error. The error has been reported on the 2000-P and as many as 11 variations might exist.

2007-P Roosevelt Dime with a die chip.

2005 Jefferson/Buffalo Nickel with a ‘speared’ bison. You can see the die crack through the middle of the Bison, and looks like a long and thin scratch.

1974 Eisenhower Dollar double clip.


1894 Indian cent double struck, 75% off center.


1867 Indian Cent 1867/67 over date.


1923 Peace Dollar die adjustment strike.

1918 Buffalo Nickel 1918/7 over date.
