Look for these state quarters!

There are two state quarters with error varieties worth a decent chunk of money to collectors. The first is the 2004-D Wisconsin State Quarter with an extra leaf on the corn cob located on the reverse of the coin. This error should be visible with the naked eye.




The other state quarter to look out for is the 2005 Minnesota state quarter. On the reverse of this coin there are couple of error varieties where an extra tree appears where it shouldn't. There are over 30 varieties of this error, but the extra tree should appear somewhere in the area indicated in the picture below. Click on the picture for a larger view (and a closer look).





Finally, across all quarter varieties, there is a chance of a die rotation error. This is identified by holding the coin with the obverse (front) of the coin held upright. Flip the coin over, pulling the top of the coin towards you, and the image on the reverse should also be perfectly upright. To get a feel for how it should look when you flip it, try it on a variety of coins. If you find a quarter (or any coin for that matter) where the reverse is not aligned with the obverse (off by 25 degrees or more) it is probably worth more than the face value and you should hold onto it.
