Lincoln Cathedral's copy has been held by the county since 1215. It was displayed in the Common Chamber in the cathedral, before being moved to another building in 1846. Between 1939 and 1940 it was displayed in the British Pavilion at the 1939 World Fair in New York City, and at the Library of Congress. When the Second World War broke out, Winston Churchill wanted to give the charter to the American people, hoping that this would encourage the United States, then neutral, to enter the war against the Axis powers, but the cathedral was unwilling, and the plans were dropped. After December 1941, the copy was stored in Fort Knox, Kentucky, for safety, before being put on display again in 1944 and returned to Lincoln Cathedral in early 1946. It was put on display in 1976 in the cathedral's medieval library. It was subsequently displayed in San Francisco, and was taken out of display for a time to undergo conservation in preparation for another visit to the United States, where it was exhibited in 2007 at the Contemporary Art Center of Virginia and the National Constitution Center in Philadelphia. In 2009 it returned to New York to be displayed at the Fraunces Tavern Museum. It is currently on permanent loan to the David P. J. Ross Vault at Lincoln Castle, along with an original copy of the 1217 Charter of the Forest.
