@Umrag:

6) I actually mentioned the barter issue. The main problem with a barter system is that it leaves open the question of what the Redwallers trade with in order to obtain weapons, armour, ammunition, etc. Leaving aside for the moment the question of who produces the equipment, Jacques never makes it clear in his books, who trades what goods for what supplies and in what way they are shipped across the continent, so the best we can do is speculate.

4) Granted, but where does the gold and silver come from? And why would anybody bother mining it in significant quantities without a monetary standard to support it?
