Off-metal coins and wrong planchet error coins are among the most valuable of rare and unusual collectible coinage.
A wrong planchet error coin (or off-metal coin) is one that was struck on the incorrect coin blank — also known as a planchet.
These off-metal or wrong planchet error coins are highly sought after by coin collectors who crave rare U.S. mint mistakes!
Examples Of Off-Metal Coins
One example of an off-metal or wrong planchet coin is a Lincoln cent design mistakenly struck on a piece of metal intended for a dime.
Another example is a Washington quarter produced on a nickel planchet.
Following are some photo examples of wrong planchet error coins…

How Are Off-Metal Coins Made?
Some wrong planchet error coins are highly unusual and may make you wonder if a US Mint employee intentionally planted the wrong planchet on the presses. Perhaps this has happened in the past… Who knows for sure?
But, in many cases, wrong metal error coins are unintentionally created when the wrong planchets are accidentally fed into the hoppers at the front of the production line.
And, given how quickly the United States Mint moves at making some of the world’s finest coins, it’s expected that a mistake may happen every now and then.
Whenever these rare coins are mistakenly made… coin collectors will always want an example for their collections!
How Much Are Wrong Planchet Error Coins Worth?
Values for off-metal and wrong planchet error coins vary widely from around $300 to more than $20,000.

Types Of Wrong Planchet Metal Errors
While the list of wrong planchet error coins above is fairly extensive, it certainly isn’t exhaustive.
Based on size
The fact of the matter is it’s possible to find off-metal error coins of any design on any planchet smaller than than the diameter of the coin for which the design was intended. (In other words, it’s possible for any coin planchet smaller than that used for a Kennedy half dollar to be struck on a half dollar planchet. But it is mechanically impossible for a Lincoln cent design to be struck on, say, a Jefferson nickel planchet.)
Off-metal coins always involve a planchet that was intended for a denomination physically the same size as or smaller than the denomination of the design with which that coin was struck.
- It’s possible to find virtually any other denomination struck by a large-size dollar coin design, such as the Eisenhower dollar.
- But it’s impossible to find a Roosevelt dime design on any other planchet — because the dime is the smallest U.S. coin made during the production of Roosevelt dimes, which were first struck in 1946.
Based on year
Off-metal error coins can refer to essentially any coin whose design is found on a planchet of a metal not intended to be struck by that design. However, some error coin collectors make a clear distinction between “regular” off-metal coins and transitional error coins.
Transitional error coins are those that were struck on coin planchets that were undergoing compositional changes during or between different (usually consecutive) years.
One of the most popular types of transitional error coins is the 1965 silver Washington quarter. Struck the first year of the copper-nickel clad era, a few 1965 Washington quarters were made on silver planchets left over from 1964 — the last year during which 90% silver planchets were used for striking business-strike coins for circulation. These 1965 silver Washington quarters are worth about $7,000 and up.
