The Triple Unite, valued at sixty shillings, 60/- or three pounds, was the highest English denomination to be produced in the era of the hammered coinage. It was only produced during the English Civil War, at King Charles I's mints at Oxford (between 1642 and 1644) and, rarely, at Shrewsbury in 1642. It weighed 421 grains (27.3 grams, or just over seven-eighths of a troy ounce). The gold coins are undoubtedly magnificent pieces of work, and they show the king holding a sword and an olive branch on the obverse, signifying his wish for peace rather than war.
