WEIGHTS AND VALUES
Two systems were used in R for weighing precious metals, Tower weight and Troy weight. Tower weight was calculated in nobles. The noble, regarded as being 1000 fine and weighing 108g., was worth 80d. (6s. 8d.), that is ⅓ of a pound sterling. Tower weights in R are often expressed as marks (2 nobles), i.e. 13s. 4d., two thirds of a pound sterling in money.
The Troy lb. of 12 oz. = 5760 grains = 374.4 g. In this system the mark represented 8 oz., two thirds of a pound in weight
Gold was usually valued in R at £1 6s. 8d. per ounce, but sometimes at £1 3s. 4d. per ounce. Silver-gilt was valued at either 32s. or 30s. per pound (2s. 8d. or 2s. 6d. per ounce), and silver at either 28s. or 27s. per pound (2s. 4d. or 2s. 3d. per ounce). Gems and pearls were separately valued and aggregated with the sum calculated for the precious metal.
