I've continued developing my fantasy settings for HARP and have started on the economy and currency details. While creating a currency system for each of the two broad regions of my setting I've found myself asking "how detailed of a system do people really want for a fantasy setting?".
My current assumption is to use a hybrid system that takes the generic fantasy currency system in the HARP books and expands it out with a few additional coins and plenty of extra details about the coins. It lacks the rich detail of a real world currency system, but also lacks it hideous complexity and math unfriendliness as well.
Here is a bit of what I've been working on (please excuse it's completely unedited state):
In the Bastion the long life spans of the demi-human natives and the structure of the Pact of Light stabilized trade and currency throughout the region. Not even the coming of Man with all their own coins and disruptive habits caused many drastic changes (the destruction of the Orcish culture and civilization being a major exception). When the Empire of Man joined the Pact of Light, Herrod officially standardized the Empires currency to match that of the Pact (although this had already been unofficially done for quite a while). The basic unit of currency here is a copper token stamped with the symbol of the minting nation on one side and Vestment on the other. The copper token contains some silver at about 1 measure silver to 20 measures copper. The most common coin used is the silver penny, showing the symbol of the minting nation and the oath of the Pact of Light in runic on the other. The silver penny consists of about 90% silver with the remainder being copper, bronze, or brass depending on the mint. The highest value coin commonly used is the gold mark. The gold mark is struck 20 measures of gold to 3 measures silver and 2 measures copper. The gold mark also shows the symbol of the minting nation on one face, but the other is a ring of 10 circles representing its 10 penny value. The most valuable coin used by nations of Bastion is the platinum sovereign pound. The platinum pound represents the value of one pound of pure silver. This coin is struck 10 parts platinum to 1 part gold to 1 part silver, with a depiction of Bastion on one face and the minting nation’s symbol on the other (however this coin is struck almost exclusively by the Dwarves). These coins are all exchanged at the rate of 10 to 1 of the next highest denomination. Thus 1 sovereign pound is worth 10 gold marks, 100 silver pennies, or 1000 copper tokens. Each type of coin varies slightly in size and weight but are all about 100 to a pound.
This is the simpler of the two currencies, the Fallen Marches still have your basic copper, silver, gold, and platinum coins but adds several intermediate coins as well.
So my question is if this is enough detail, too much detail, or not detailed enough. I plan on rewriting this for readability, fixing any errors I spot and add some tables eventually, but I'm just wondering how much detail do people like in their setting's currency.
Thanks,
