Hades, he even gets the riches that, say, are lost, or disposed of, and since precious metals and jewels aren't corrodible, he'll get them back anyways.

Iris does have her store and the drachmas or whatever, but the amount is much less than that of Hades' riches.

And Hermes? meh. He is the god of thieves, after all. If he wants to, he can steal all of Hades riches. Maybe.
