The Museum revalues the National Historical Collection every three years in accordance with the Guidelines for Financial Statements of Commonwealth Authorities and Australian Accounting Standard 4 (AAS4). Revaluation took place in 2002-2003 and as at 30 June 2003 it was valued to be $132.212 million, including the library collection. This was a moderate increase over the previous valuation figure of $128.286 million as at 30 June 2000.
Individual valuations of objects received by the Museum are also undertaken throughout the year by external valuers to meet requirements for the Commonwealth Government's Cultural Bequests Scheme managed by the Department of Communications, Information Technology and the Arts. Valuations are also undertaken prior to objects being loaned to other institutions, or for material destined for travelling exhibitions.
