The US mint released the Vicksburg Quarter August 29, 2011, the 9th release of the America the Beautiful series. The quarter portrays the Vicksburg National Military Park on the coin’s reverse.
As of now, there are no major error varieties of this coin.
I have a 2011 Vicksburg with the 2011 being printed high and actually and the waves where the water starts at the bottom of the coin it was very obvious by that Eye. If you would like a picture send me an email and I will send it
