What is worth? part 1/?

Following from the previous post, now I have a money system. But it's not very useful to know that one throne is worth 500 bweepers, when we don't know what a bweeper is worth. So know I need to figure out what everything is worth.

We know have the following units:
Bweeper
Double-whistle=25 bweepers
Throne=20 double-whistles
Hmm. Double-whistle is a little cumbersome to say or write. I imagine that it would get shortened pretty quickly in spoken language and generation or two later it would be shortened in written language, too. I think just dropping the whistle part should be sufficient. So one throne=20 doubles.

Back to the topic. I should aim for the values to be at the very least realistic enough for casual observer to fail to spot anything obviously wrong. Bweeper should be small enough that it's fractions don't come into the play. I think I should start from a small village environment where there aren't that many variables. In small village with little connection to outside world apart from the occasional peddler, most of the trade is direct exchange with items and services without money being necessary.

Most people are farmers or hunters who do a little bit of everything from fixing their tools of trade(when it can be done without a forge) to making their own clothes either from wool(or equivalent, more likely) up or at least from fabric. These people are in effect nearly self-sufficient: as generalists they rarely have need for specialists, even though they would get better quality work from using one. Farming isn't very lucrative, so their net-worth isn't very high.

A village also needs a blacksmith. Farmers could probably make their own forges, but considering that a forge needs yet another separate building, it's heavy work and they don't have that much use for it themselves, it just isn't worth it. In the end a professional blacksmith is better for everyone. There are several other trades that probably have a specialist: a healer/priest who knows mostly everything there is to know about different herbs and treatments in the collective wisdom of village there is to know. Again, farmers probably could know these things themselves and probably do know at least the basics, but when you're really sick you're going to need help, anyway. There's also some kind of mayor who acts as spokesperson, judge/arbiter etc. Mayor probably has a side-trade too, at least in smaller villages. With the danger of cave-ins being everpresent, there probably is an architect as well, to regulate building. There may also be a magic-user, but since one isn't strictly necessary, it's more likely that one has taken the role of healer and uses other magic only irregularly.

I've already written almost 500 words and I've barely scratched the topic I intended to write about. On the plus side, now I have all the necessary pieces to grab the issue. I think I'll leave the rest for tomorrow. I clearly need to think about this some more.
