Phew, been a while since I've been able to post.

My dev team's solution for the 'currency' problem was to throw them all
away. We use a 'barter' system, meaning that a 'coin' is a lump of
substance with an actual (and inferred) value. A gold coin weighing twenty
grams might have a value greater or less than 20g of gold in an area where
said coin is recognised as legal tender. Outside these areas, it assumes
its value as a lump of gold.

The idea here is that when a currency is required (for instance, suitable
silver coins for a Rome-like town), it can be added locally, and is
useable globally (recognizable as the currency of this particular town or
region). Any kind of object can also be valued and traded with Shopkeeps
who will accept that type of item (grocers won't be interested in swords,
for example).

Incidentally, one of the nice effects here is that you can 'trade in' old
gear for new gear, and then pay the 'balance' between them in money,
rather than needing to explicitly sell items, get money, buy items, and
pay money.
