Seven Voyages of Zylarthen uses a silver standard. That is, the prices for adventuring items are quoted in silver pieces and the experience points needed to gain levels (which approximately track the numbers of OD&D) match up with silver pieces, not the gold pieces of OD&D.
It's not original.
Lamentations of the Flame Princess does it. And even Gary Gygax himself implied that he might have done it if given the chance to do Dungeons & Dragons over again.
Well, first of all, it's more historically accurate. Silver has always been much more plentiful than gold (while remaining rare, with additional stocks difficult or costly to obtain) and thus better suited to minting coins. Here are some rough facts:
- The silver penny of Medieval, Renaissance or Tudor times in England was about the size and weight of a modern dime.
- The silver shilling (worth twelve pennies) was about the weight of an Eisenhower Dollar, though with a somewhat smaller volume.
- Very very roughly, and taking into account expected oscillations, debasement and subsequent inflations, in-kind payments and so on, a shilling was often equal to a day's wage of a farmer or manual laborer. Or conversely, it was about what you needed to pay for a day of food and shelter. People often cut pennies into quarters to pay for cheap items.
- Historically, gold was always 5-20 times more valuable by weight. Or since gold was twice as dense as silver, 2-10 times more valuable by volume.
- Thus, depending on the ratio of gold to silver, one could carry a year's salary in a belt pouch and a large fortune in a small sack.
- Silver shillings or gold sovereigns—'pound' coins equal to 20 shillings—weighed about half as much as the 1/10th of a pound stipulated in OD&D and AD&D. (For much of the period in question, 'pound' and sometimes even 'shilling' were so-called units of account, rather than names for actual coins.)
For More Things in Heaven and Earth (my '16th century' proto-Zylarthen) I created a very fussy (but fairly historically accurate) table of coin weights and values:
(An encumbrance 'item' is roughly equal to five pounds of weight, similar to the encumbrance scheme of Zylarthen.)
It was wise to jettison the above for Zylarthen, but I will probably use it in my pending 'Tudor' or 'Elizabethan' supplement.
However, much more important than 'realism' was the way that the monetary values and exchange rates of OD&D completely undercut a robust and varied coin system. Since even mundane and cheap items were expressed in terms of gold, it wasn't clear what purpose copper and silver really served. Why would any but unintelligent monsters hoard such coins? But the Dungeon Expedition example in The Underworld and Wilderness Adventures along with of course the Treasure Tables themselves, seemed to suggest that they did—'The chest with the poison needle is full of copper pieces—appears to be about 2,000 of them'. It was as if modern day gangsters did much of their business in pennies, going around with sacks of them, keeping them in elaborately protected safes, etc.
So for Seven Voyages of Zylarthen I, so to speak, shifted things one column to the left, with the standard metal of account now being in the middle of the other two. I kept the variance in values from lowest value coin to highest value coin at 1:50 the same as in OD&D, though this is much narrower than the 1:200 variance in AD&D that many of us are most familiar with. Here are the relevant comparisons:
Seven Voyages of Zylarthen:
The 1:5 copper to silver exchange rate allowed copper pieces to still maintain some meaningful value and give men and monsters a reason for hoarding them. On the other hand, I wanted gold to become something truly valuable, sort of like the status of gems in OD&D, which I thought made more sense both from the standpoint of 'realism' as well as how gold is usually treated in fantasy stories, fairytales and the like. Basically I wanted to give it more allure than just something you use to buy a coil of rope with.
I've heard that referees wanting to switch from a gold to a silver standard often run into opposition from their players—'he's taking our gold away!'. So I would be interested to hear from any Seven Voyages of Zylarthen play testers out there as to how the silver standard has worked in practice.
UPDATE ON TEAM OLA: A number of wonderful and generous people have pledged $500 since last Wednesday to sponsor my Chicago Marathon run in support of the Our Lady of the Angels Mission on Chicago's West Side. Thank you again! I am very grateful.
I still have $500 to raise by Marathon day, Sunday, October 12th. Only four days left! If you haven't already done so, please consider sponsoring me in support of a group that does great work! Any gift of $75 or more will launch either the four Seven Voyages of Zylarthen physical booklets or a cool Steve Prefontaine DVD on an inexorable trajectory towards your home. My donation page is here:
Donate to Team Member Oakes Spalding (again, it goes directly to the Mission, not me).
