In #AnimalCrossing the retail value of the donation box increases 1:1 with the money inside of it.
Though Nook's Cranny has a randomly selected hot item of the day. That item can be sold for double it's normal price, that day only.
So if the donation box is the hot item of the day. You can effectively stuff it with currency and get two bells for every bell you put into it.
