Fine Sovereign - The fine sovereign was a large, high quality gold coin of 240 grains and was so named because the gold sovereign of 1550 represented a return to the original "fine gold" standard of pre-1544 (before the debasement antics of Henry VIII). The fine sovereigns were minted at 23 carats and 3.5 grains of gold to 0.5 grain of alloy  - a purity of 191/192 or .9947917 (i.e. 995).
