What is the value of a 2011 quarter with a green ram on one side?

The 2011 quarter with a green ram on one side is likely not a standard U.S. coin, as quarters typically feature the image of George Washington. If the coin has a specific design or marking not recognized in regular circulation, it may be a novelty item or a collector's piece. To determine its value, you would need to research its rarity and demand among collectors. If you believe it's a special edition or error coin, consulting a numismatic expert or reference guide would provide more accurate information.
