The Chickasaw National Recreation Area has been protecting and preserving peaceful meadows, sparkling springs and streams, pristine lakes and other beautiful natural features for more than 100 years. Showcased on the reverse of the 2011 quarter is the quaint Lincoln bridge, dedicated in honor of the 100th anniversary of Abraham Lincolnâ€™s birth. The bridge stands astride a quiet stream while birds fly overhead. Also written along the quarterâ€™s edge are the words CHICKASAW, OKLAHOMA, 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.
