Birmingham and Stoke City Councils are fundraising to buy the hoard
More items belonging to the Staffordshire Hoard, Anglo-Saxon artefacts found in the county, are to go on display in three cities.
A selection of 59 items, including helmet fragments not seen previously in the city, will go on display in Birmingham from 13 March.
The same number of items are going on show in Stoke-on-Trent. The two displays will run until 18 April.
During this time, 10 items will be shown at fundraising events in London.
The treasures can be seen at Birmingham's Art Gallery and Museum and at the Potteries Museum in Stoke-on-Trent.
A recent display at the Potteries Museum raised £152,000 towards a campaign target of £3.3m to help the hoard remain in the West Midlands.
The total funds raised stands at £1.5m. If the target is not reached by 17 April the hoard may be divided up and sold to private collectors.
The Staffordshire Hoard was discovered by metal-detecting enthusiast Terry Herbert last July.
