This is interesting...I came up with an idea similar to this just earlier today. There's a good example with the Battle of Lumbridge and the Duke's emergency fund. I think Lumbridge is a fair-sized town, but it's no capital. Lumbridge is mainly a farming community, so it probably wouldn't be the richest of towns. It's got the 160k GP emergency fund. That's probably not the entire treasury, just what's set aside in the budgit of reconstruction and reinforcement. If this would accurately represent the value of coin in lore then I'd imagine a small town's treasury may be 500k-1m. Of course though, it depends completely on the town, where it's at, how its economy is, and factors like that. A large city with slums, such as Varrock and West Ardougne, may not have treasuries that reflect their actual boundary sizes.
