In the 1991 multiplayer AD&D RPG on AOL, Neverwinter Nights, you used to be able to buy packs of +1 arrows in a far off town in the game called Red Larch, split the arrows up, sell them at the shop, and make more money than they cost.
You could basically make as much money as your character could hold. If you then traveled to a jeweler or the vaults you could stash the money, convert it to lighter gems, and do it again. Not many people knew this and you could generally trade for most items that came as treasure with these gems. So you could buy +3 plate mail or whatever. Usually obtained from hours of work killing drocoliches or whatever.
I guess if everybody had been doing it, the in game money would have been worthless, though.
