- Each of the 4 daily quests for the home city that you're currently working on give 13g at level 80 and 250 reputation for that city, and 25% of that towards the other home cities.
- Each of the 4 daily Champion quests give you 250 Argent Crusade reputation, and either a Champion's Purse or Champion's Writ.
Let me sum it up another way:
Either up to 5000 total reputation and 52g - or up to 3000 total reputation and 92g.
At least those are the totals while you're working all for home city reps to Champion. Not sure what happens when you're Champion with everybody. Still, on the path there, you can get up to 100,000 reputation! (Don't check my math on that last one, I already know it's a bit off since you're not completing Champion Quests on your first path to Champion.) Oh, and that's about 1,000g as well. Granted, we're talking about 20 days of dailies, but since I still find them fun, I don't mind that as much.
