A mixture of public and private donations helped the museum reach their required total including a £10,000 grant from the Arts Council England/Victoria and Albert Museum Purchase Grant Fund and a donation of £9981 from the American Friends of the Art Fund.
“We are thrilled that so many people have given so generously to allow us to buy this hugely significant find,” said numismatics curator Andrew Woods of the Yorkshire Museum
The hoard, which dates from 307AD, was discovered in 2014 by detectorist David Blakey. An appeal to save the hoard was launched on July 25 and attracted hundreds of private donors from around the world.
More than 1800 Roman nummi, each measuring around 3cm, are in the hoard. They depict a number of Roman emperors including Constantine and Constantius.
It is the second largest hoard from the period ever found in the UK; the largest, the Fyfield Hoard is in the Ashmolean Museum which launched another campaign earlier this week to secure large collection of recently-discovered Anglo Saxon coins.
A large portion of the Wold Newton Hoard and the ceramic vessel in which it was found remain on public display at the Yorkshire Museum until January 11, 2017.
