It was to add some flavour. Daras(GP) is elvish for gold, Sark (SP) comes from the old practice of cutting a Daras piece to make a smaller currency, Untora(PP) means moon because the platium pieces look like moons elvish, emrala(EP) is this world's name for an emerald, which that currency is made from and Untor(DP) is the single most important being in the multiverse hence his name is attached to the most important coin. You may call them SP,GP,PP,EP and DP repectively. I have no copper piece listed there as I hope players will not get that broke and the main stay for workers is a sark (SP). This help?
