THE smallest details can be worth the most money when it comes to coin collecting.
Fine details are often the difference between a coin worth a few hundred dollars and one worth a few thousand dollars, like a penny that sold for nearly $9,600.
One of the most common types of error involves the mint mark.
The mint mark is a small letter stamped on the coin, denoting the US mint where they were made.
Coins from San Francisco usually bear an S, coins from Denver are marked with Ds, and so on.
There can be a few different errors related to the mintmark, including missing and duplicate marks.
