A small collection of artefacts associated with the work of the Royal Mint Refinery. 

A Balance Beam weighing scale and three sets of weights, mounted in a wood and glass case was used at the Royal Mint Refinery to weigh gold, and after the Refinery closed in the late 1960s, was displayed at New Court until the third New Court building was demolished in 2008. This will be found listed as 000/2176 under New Court: artefacts.

Royal Mint Refinery: artefacts, box of precious metal samples, c.1860

000/1911/41, 1 item

Wooden box, about 25 cm square, containing samples of precious metals. Its origins are unclear, but it may date from the days of the London bank’s early involvement with the mining and refining of Australian and Californian gold from the 1850s. The box contains four samples of the precious metals that make up a Mexican Piastre, a gold bar from Australia and gold from California, and gives (in French) the precise proportions of gold, silver, copper, platinum, iridium and lead in each of the samples tested. The box may have been given to the Rothschild partners as a gift, or possibly it was made up by the first staff of the Rothschild Royal Mint Refinery, based on tests of gold made at the request of Sir Anthony de Rothschild (1810-1876) the driving force behind the establishment of Refinery. If so, it may be one the earliest surviving relics of this important industrial enterprise.

Examples of Molybendum wire, gold plated wire and other metal objects produced by the Royal Mint Refinery. The Royal Mint Refinery was owned by N M Rothschild & Sons for over 100 years, occupying premises at 19 Royal Mint Street in London. For many years the activities were principally concerned with refining gold for the Royal Mint, which was located adjacent to the refinery. During both World Wars, the Royal Mint Refinery was diverted to the production of munitions. After the Second World War the business was diversified to manufacture copper and brass strip, refine silver and de-monetise coinage.
