We’ve gotten quite a few questions about mistakes on coins lately. Here are a couple…
Hi. I have a one sided roosevelt dime. It has a torch on one side the face side is blank.” —Pete
I received a dime at a quiznos the other day. It is a 1943 mercury dime on front and the size of a dime. I do not know a lot about coins. However the back of the silver dime was the same as a wheat penny. Is this common. again Mercury dime on front wheat penny on back.” — Jim
The Value Of Coins With Mistakes
What Jim and Pete have here are “error coins”.
Millions of coins are released each year by the mints, so it is no wonder that a few abnormal coins slip by inspection and out into population.
These abnormal or misshaped coins are called misstrikes and errors. Error coins are highly collectible and usually command a lot higher price than if the coin were struck normally.
However, it is difficult to put a value on coins such as these since nearly every misstruck or error coin is unique in some way or another.
There are several varieties of errors. Some of them include:
Clipped Planchet — An incomplete coin missing 10% to 25% of the metal.
Multiple Strike — A coin with at least one additional image from being struck again off-center.
Blank Planchet — A blank disc of metal that was intended to be made into a coin but never got struck by dies.
Defective Die — A coin showing raised metal from a large crack in the die.
Off Center — A coin that has been struck out of collar and incorrectly centered with part of the design missing.
Wrong Planchet — A coin struck on a planchet intended for another denomination or of the wrong metal.
Lamination — A flaw where a fragment of metal has peeled off of the coin’s surface.

Other Types Of Error Coins
There are other errors as well for modern coins that have been clad or plated wrong — which explains why some of the people posting have “gold looking” coins that shouldn’t look gold.
These normally aren’t worth very much. I am not a huge expert on all the types of error coins, but generally for an error coin to be worth big bucks it would be one that you look at and immediately think “Wow, that’s messed up.” LOL
I have been collecting and trading coins for years. Coin collecting is a hobby for me, and I’ve done a lot of research about coins through the years.
