This is a 1958 Denver Silver George Washington Quarter.  What makes this quarter unique is that there is a crack on the front of the quarter on the top of Washington's head and base. 

 I want this to go to someone who will appreciate this more then me.  I had the fun of finding the error in the coin and I want to pass this along to someone who will enjoy it more then me.  

The Reverse side there is a crack left wing, and crack on the Eagle's head.  Crack on E PLURIBUS UNUM.  Right wing and Double Die "D". 

I have provided you pictures of the quarter and please ask any questions about the quarter.  Or if you needing picture pictures I will try to get assistance it was hard holding the camera and then having to click the take picture button.
