George V (1910-1936), Proof or Pattern Threepence, 1925, struck in nickel (ESC. 2149B-R6). Mint state or virtually and excessively rare (£300-400)
The extremely rare experimental strikings by the Royal Mint in nickel in the 1920’s deserve further study. Their existence suggests the Treasury were considering the adoption of nickel for the lower value English silver coins; alternatively they may have been made in connection with contract work for other countries, and perhaps significantly the new Sixpences and Threepences for the Irish Free State released in 1928 were of this metal. An examination of government and Royal Mint archives would, one feels, reveal much.
