An appeal has been launched with the aim of raising £3.3m to buy the Staffordshire Hoard which was discovered in July 2009.
As many as 1,500 gold treasures were found in a field near Lichfield by metal detectorist Terry Herbert.
If the campaign manages to raise the £3.3m required by 17th April the hoard would be jointly acquired by both the Birmingham museum and the Potteries Museum and Art Gallery in Stoke-on-Trent.
Birmingham and Stoke-on-Trent city councils and The Art Fund have together donated £500,000 to the cause. The hoard was valued in November after being declared to be treasure by the South Staffordshire coroner.
Once the hoard is bought, an extra £1.7m will be needed to ensure it can be properly conserved, studied and displayed.
Donations can be made to the campaign on The Art Fund website.
