Morgan had also acquired a major part of Sir John Evans's coin collection, which was later sold to the museum by his son John Pierpont Morgan Junior in 1915. In 1918, because of the threat of wartime bombing, some objects were evacuated via the London Post Office Railway to Holborn, the National Library of Wales (Aberystwyth) and a country house near Malvern. On the return of antiquities from wartime storage in 1919 some objects were found to have deteriorated. A conservation laboratory was set up in May 1920 and became a permanent department in 1931. It is today the oldest in continuous existence.
