Currency in the Exiled Kingdoms

Arnor and Gondor Currency The Kingdom of Gondor and most of the former provinces of Arnor had preserved the ancient Númenorean currency:
Double-Dragon or ducat = Gold coin of the highest Value (approx. 0,16 ounces gold) Mirian (a goldpenny) = gold coin (approx.0,04 ounces gold) Castar (or Canath) = Silvercoin, 1 quarter of a Mirian (approx.0,01 ounces gold) Tharni or silver farthing (a Fourpenny) = 1 quarter of a Castar (0,28 ouces Silver) silver penny (approx. 0,07 ounces silver) Brass coins (Brasslings or Buttons) = 1/4 Silver Penny (approx. 1 ounce Brass) copper coins (Copperlings or Quarters) (approx. 0,28 ounces copper) In times of need, the Lords of the Westlands had also often introduced necessity money, made of Tin (often 1 ounce Tin), Lead (often 0,01 ounces Lead) or Zinc (0,12 ounces Zinc). For small transactions people also often cut coins of greater value into pieces and paid with hack-silver or even hack-copper. As everywhere purity and worth of the different coins could differ significantly throughout the ages.
Tin-Coins = approx. 3 copperlings Zinc-Coins = approx. 1/2 Copperling Lead Coins = approx. 1/16 Copperling
