Currency Issues

Your scheme, as with all, would depend on the society in which it is used.

For me, everything below Golden Coin seems pretty good & useful. Golden Coin is stretching it a bit, because a single coin worth $1562.50 would be used....how? Maybe in trade with other nations, or large trade items between nobles, or in gambling amongst nobles, the Golden Coin would find its place. The Golden Coin might also be used to buy large trade items from wealthy merchants/dealers. The problem however in dispersing it beyond the nobility is the question of how non-nobility could use it. For trade with those below nobility and wealthy merchants, I suppose it could be broken down (once received) into Gold bits. My point is: it becomes clunky outside use among nobility and wealthy merchants. So it's borderline.

The Gold Throne and Emperial Gold Throne seem altogether too valuable for practicality—particularly the latter. Perhaps, again, amongst the extremely wealthy these could find some use. Or for storage, i.e. hoarding gold. More practical than giving someone a Gold Throne would be giving them 5 Gold Coins, for instance.

I'm not sure of the sizes of these coins, so can't make an argument there, although I wonder at the size of an Emperial Throne if it is to be worth 500x a Golden Coin. Are we talking a coin that is 10 inches in diameter? :confused2:

Again though, much would depend on the type of society you have, the size and complexity of the world. I think one could design a world and society in which such uber coinage would find a place, but it would need to include some extremes beyond typical medieval-ish size and complexity.

 

My general point re: the above is that, yes, the poorer classes wouldn't be using higher currency, but how would the wealthier classes be using it? Suppose a wealthy merchant receives a gold coin from a noble in payment for an extravagantly carved bed. Now the merchant has the gold coin. Can he use it to pay his laborers, his personal servants, or food sellers in the market when he's buying groceries? But then, if he does use it to pay these folks, how are they then going to use it? Breaking it down into gold bits seems like a plausible way for it to be used for paying these people below the wealthy merchant; otherwise, he is constrained to use it when he himself buys big-ticket items from other wealthy merchants. Or for gambling amongst other wealthy people he knows.

You had also given the example of paying an assassin with a Gold Throne. Well, then what is he, the assassin, going to do with that Gold Throne? How spend it?

As for the rest of your reply....You yourself gave a sort of value breakdown of each coin, which is why I responded as I did. The reading audience isn't going to need to know the actual value breakdown, i.e. in terms of dollar amounts, but only needs a general sense of scale. Obviously you can make up any set of words you like and go with "B is bigger than A; C is bigger than B; D is bigger than C...." as a guideline while writing. I'm just curious about why you asked with such specificity re: value amounts when in the end you only need a vague scaling set of terms to achieve a sense of scale.

 

For a semi universal currency system, you might consider how the US currency works, or any western country (I know little to nothing about other currencies so I can't use them as examples).

Let's disregard electronic banking for the sake of this discussion since it will just muddy the waters.

In the US, the base denomination is the Dollar (you should decide on a base currency for simplicity's sake, be it the silver or copper coin, it shouldn't matter but I'd not use the gold coin). The largest denomination is a $100 bill. Anything extraordinarily above that amount is dealt with outside of a physical currency system and substitutes are used instead; these must be backed by an institution of some kind, be it bank or government or what have you. Thus people would use something like Checks, bonds etc.

Currency larger than that is, in many ways, just impractical. However, having a name for large quantities above that might serve a purpose for trade, especially for banks and lending houses. But no one mints million dollar coins because... what would you do with it? Sure, you could buy a castle if there was a reasonable amount of difference in the actual price (reasonable meaning, change could be made). But, in most circumstances, you'd have to go right to a bank (a large one) and deposit it, taking out a reasonable amount for spending in more manageable currency sizes/amounts. So, your Golden and Emperial Thrones would be conceptual, not hard currency; at least, logically they would be.

The other issue is this: copper, silver and gold have actual value. They require no 'backing' like, for instance, paper money. So, your coins would not have a hard value in dollars (which you have used as an example). It would in fact be the other way around. Dollars would have a specific value in gold, etc. So, Skip.knox makes a good point; using commonly purchased items as a basis for value makes more sense. This means, in a system with both intrinsically valuable hard currency and conceptual currency, that the value of conceptual currency would change. One day an Emperial Throne would be worth 500 golden coins and then next it might be worth 498. And the next day, 502. Thus, the combination of intrinsically valuable hard currency and conceptual currency can get pretty complicated. All it takes is the introduction of a common practice like shaving gold coins and things get pretty precarious in your fantasy economy.

Obviously, none of this ever needs to be explained in your book. Your basic system would work great. Unless you're writing about the richest characters in your world buying and selling quite often, the mention of Golden Thrones and Emperial Thrones would simply be an occasion of awe for most people and it would only need to be clear that it's a lot of money, not exactly how much.

EDIT:

The shaving gold coins thing made me think of something else. The reason American coins have ridged edges is because of the practice of coin shaving (note that pennies don't have ridges because they were typically worth more as coins than as raw material). With smooth edges, coins can be shaved, decreasing their weight and thus their value. The shavings could then be put to use to forge currency, make gold jewelry (basically for free) or just to be used in rough form for trade, again, by weight. However, American coins no longer have intrinsic value since they aren't made out of precious (gold & silver) or useful (copper) metals; the ridging is just tradition I guess. They are now backed currency like dollars (which are really just bank notes anyway). So, I guess my point in this edit is to show further how complex mixing currency systems is. It's doable but would probably result in gold coins getting weighed by merchants all of the time (unless of course they had hard-to-fake ridged edges).

 

Something I used to wonder about and still do, now and again. I know that folks in the ancient world were big on hiring mages - thinking Roman era 'curse tablets' and 'love spells' here - but never really ran across much about what these services cost. Also, all manner of books contained spells and incantations of one sort or another, most outright ridiculous. The real books on magic were kept secret, which, ironically, is why they turn up now and again - they were that well hidden, and hence protected. But not much info on monetary value for such a book.

In my own writing...I ran into a dilemma. On the one hand, magic should be rare and wondrous and therefor expensive. And there are not a lot of true mages on my worlds. On the other hand, if magic costs too much, especially for the common spells (protection, love charms, divinations, that sort of thing), then the wizard is liable to price himself out of business...or into the local palace. But wizards in my worlds are near outcasts anyhow, or part of the church.

I ended up making them either academics at a handful of locations, or wanderers, alternately selling spells in marketplaces or taking short term gigs with this or that merchant or noble. The church does something similar with Godborn (healing mages).

But back to more or less on topic:

You are almost certainly going to need a coin with a value of around 1/10th to 1/5th that of a copper - a coin that will buy a loaf of bread, bowl of stew, mug of ale, or a spot in a shack or hostel. (I'd suggest either a bronze or iron bit.)

For that matter, you don't really need any coins of greater value than the gold bit - and even that will be the domain of merchants, prosperous artisans, and the government.

Most non-menial folks will be using silver bits for the big bills (rent) and copper or iron/bronze for the small stuff.

And, of course, the value of coins will vary from place to place depending on where they are minted. 'Coins from Kingdom X are known to be debased, hence we won't accept them.'

 

I based my world's currency in coins of precious metal because I like boring, normal-like setttings like that.

My lowest value coin is roughly worth a quarter. I figure that's about the price of an apple, about the lowest currency transaction that's worth anyone's time. If you have something worth less than that, you better sell in bulk. I built up from there to coins worth about $10,000. These are basically for the money houses and rich nobility. Has anyone in my world needed one? Not in anything I've written yet. Shrug.

The big thing for me, though, was to have a dose of reality by only making coins out of materials available on the continent. I was going to have brass coins, but there's no zinc mines, so I had to get rid of them (because I didn't feel like adding zinc mines).

This is just for my main continent, though, other continents have their own currency based on the materials available there. The major port cities have money houses that will exchange currency for a fee.

 

My biggest concern as far as currency was mostly about how it would transfer from civilization to civilization, like how the currency would be exchanged. i was able to fix this by basically just setting up a global trade group called The Merchants Guild, which dealt with exchange rates and creating a uniform currency to be used throughout the world. essentially, every civilization still had its own currency, but there was always a globally accepted system of coin for travelling merchants and wandering adventurers. The only groups that wouldn't accept these coins were primitive tribes, but they mostly still operated on the barter system and the exchanging of goods. as far as exchange rates for the global trade currency, i mostly just left that alone, as i simply had far too many empires for which i would have to create currencies.
