Mint Errors: Mint errors are a fascinating branch of numismatic because not only are they interesting to look at, they also provide insight into how coins are manufactured. For example one type of Mint error is the off-centered coin, which is made when a coin is not held in place by the collar. Similar to an off-centered coin is a broad strike. In this Mint error, the coin is also not secure in the collar, but all of the design is present; however, the reeding or other edge design is missing. Another type of Mint error is an overdate. In this case, the die of a normal dated coin is struck by a hub with a different date, creating one date on top of another. Sometimes a coin is struck on a planchet designed for another coin. A wrong planchet Mint error is created when a planchet gets stuck in a tote bin and is mixed into the planchets for another coin. A Lincoln cent struck on silver dime planchet is an example of such a Mint error. The most spectacular error coins are those that are mistrikes or planchet errors on larger coins. One that combines these two errors is a mule. This Mint error is a coin that is made from two dies not intended to go with each other. A cent obverse with a dime reverse would be an example of such a coin.
