Yeah I get that, I was trying to go for a small leather purse, but yeah now that I've implemented it I realize they're Scrooge McDuck-sized money bags. Although the content could still be anything.. Apparently you need about 23520 half-pennies to make a single dragon... sooooo the small vendors are bound to have a lot of coins. And the bag doesn't give away what coins they are.The coins are nice, but the bags may be an issue since we not so recently changed then from all gold coins to a mix for the purpose of making sure they can be used from lower class at markets to upper class treasuries.
Adding these really large bags of money may negate that affect since I doubt a vegetable vendor in a rural area would lug around a sack of coins for their vegetables.
I'll try something smaller though to see if it works at the scale.
