Re: OT: coins and currency (was: [Theory] Types of numerals)

I think a con-currency (there's a good pun there somewhere involving
multithreading, but I'm too sick to think of it) is an interesting
problem on its own, if more conculturing than conlanging.  There are
competing goals: minimize the number of denominations, while at the
same time minimzing the number of coins needed to represent any given
vale.

In US currency, for instance, there are essentially 4 sub-dollar
denominations (1, 5, 10, 25), since half dolalrs are very rare.  As a
result, some values require up to 9 coins (e.g. 94¢ and 99¢).
Reintroduction of a commonly-circulated half-dollar would cut that
down by one coin; a two-cent piece would reduce it by two more.  That
would yield six denominations and a maximum minimum (:)) of six coins
per value.

Have y'all designed currency systems for your cultures?
