What is a coin mint error?

And obverse? I read that some coins were obverse. What does that mean?
I read about coins that had mint errors.. What are mint errors? And how can I tell if a coin has one?
Also, what is a reverse error on a coin?

    Off the top of my head, the ones I remember are:
    double die (stamped twice)
    defective die (when there is a piece of the picture missing, but enough room for it)
    off center punch
    when one side was not punched.

    A mint error is a mistake that was made during the production of a coin. There are many types of errors on all types of coins. These mistakes are caused by malfunctions in coin stamping equipment mostly. But can also be caused by human errors. Some times the mint catches these errors and destroys them other times they slip through undetected and end up in circulation. To spot an error examine a coin closely and look for any imperfections in the lettering or design. Some are very obvious some are difficult to spot. Do an online search with the words ‘coin errors’ you’ll find many web pages that have photos and descriptions of these errors. Believe me there are too many too mention here.

    The Obverse is the face or heads side of the coin. The Reverse is the back or tails side of the coin. When they say obverse in U.S. coins they are referring to the side with the face.
