Coin Errors--Does That Penny Look Right?
The United States Mint has some of the best quality control in the world. But now and then errors occur as coins are made, and some of those errors make their way into circulation, and therefore into the hands of the public. And when those coins get into circulation there are thousands of people who are interested in collecting them! Some people find them interesting or curious. Some people are interested in figuring out what went wrong to make the coin look that way. And some people find error coins to be great investments.
"Boy is That Penny Messed Up!"
That's what my daughter said when she saw her first error coin. It was a Lincoln Cent which had been struck 47% off-center. And she was right, that coin was really messed up!
Have you ever gotten a coin that just didn't look right? Maybe it was the wrong color. Perhaps the lettering looked blurry or doubled. Maybe there was even a letter missing! Was the buffalo on the nickel missing a leg? Did Honest Abe just seem to have too many fingers? Maybe it looked like a bolt of lightning was striking our sixteenth President in the head! Did it look like there were two numbers on the date where there should only be one? All of these things, and even more, have occurred in the minting of United States coins. If you get one, don't throw it away. If it is genuine it may be worth ten, a hundred, or maybe even a hundred thousand times face value!

FDR -- Right of Center?
Sometimes coin errors can make you smile if you put a little thought into them, and you don't find them too "pun"-ishing. Here's a Roosevelt Dimes that was struck off-center making it appear that FDR may be just a little bit Right of Center.

An Error on the Kansas State Quarter?
In God We ... Rust? I've Heard of Separation of Church and State, But ...
This is a photograph of the "Rust Quarter." Actually this is a real Kansas State Quarter minted in 2005. Minting coins is a mechanical process, and in order to prevent damage to the machinery which makes the coins grease is used to reduce friction. In this case grease made its way to the die which produces the image on the coin, and got into the of the first "T" in "Trust." The resulting wording therefore appears to be "In God We Rust." This type of error, known as a "Struck Through Grease" error, or a "Filled Die" error, is fairly common, and in this case humorous (or blasphemous).

Year and mintmark are another way that collectors differentiate one coin from another. But collectors of error coins need try to classify their coins by the type of error that the coin exhibits.

A Recent Acquisition
An 1864 Two Cent Piece exhibiting a Repunched Date. Note the doubling on the first digits of the year. I especially like the fact that this is a "first year" coin, which is one of the areas on which on concentrate.
