The Ansell variety Sovereigns represent the successful culmination of the experiments of Mr George Frederick Ansell (1826-80) who worked as a chemist in the "Rolling Room" at the Mint in this period. A consignment of gold mined in Australia when annealed ready for minting proved to be too brittle for use in coining and Mr Ansell was given permission to experiment with it to strengthen it for use. When melted down the brittle Sovereigns were found to contain the wrong quantities of alloy of arsenic, antimony and lead. Mr Ansell successfully altered the alloys and subsequently 167,539 Sovereigns were struck from this consignment of gold all denoted with the extra raised line on the fillet perhaps to see how they would then fare in circulation. Despite the success of this coinage, Mr Ansell eventually lost his job in the Mint circa 1867 due to internal quarrel, and then worked as an analyst. He paid particular attention to the Mining industry and patented a "firedamp indicator" as well as continuing to write articles on coining. Ansell is recorded on the 1871 Census as an Analytical Chemist, married to Sarah with three sons and two servants at 27 Bernard Street, London. Ansell died at age 54 around Christmas time 1880.
