Guinea coinweight (2)
Although this is not an actual legal tender coin, it is intrinsic to the use of coinage in England in the late 1700s. The image shows the obverse and reverse of a guinea coinweight from the reign of George III. New legislation came in in 1775 to redefine the weight of a (gold) guinea and these coinweights were used to check coins which were offered in payment. The figures on the reverse show that this weight was 5 pennyweight and 8 grains (24 grains = 1 pennyweight = 0.055 ounces = 1.56 grams) and the peculiar-looking mark stamped between the 5 and the 8 is an (inverted I think) coffee pot, the mark of the Founders Company in London indicating that the coinweight has been checked and certified correct. The weight is 20 mm (3/4") in diameter.
