Celebrating the 47-day Siege of Vicksburg, the 2011 quarter features the U.S.S. Cairo. Although sunk during the pivotal battle, the Cairo was eventually raised. It is pictured on the reverse of the quarter as it would have been seen while in all her battle glory. Also written along the quarterâ€™s edge are the words VICKSBURG, MISSISSIPPI, 2011, and E PLURIBUS UNUM. As circulated quarters continue to be difficult to find, these collections will become a premium item. Uncirculated State Quarters are a rare find and continue to climb in value and demand. Quarter prices are subject to change without notice.
