If trading is implemented, what would you trade?

If we get some sorta of trading system, what are we going to trade. We have gold, so is it going to be rare clothes drop.
Or maybe something like trading our treasure for a baby Kraken in a fish bowl type thing.

What do you have you think you would want to trade to other players/npcs, and what is you want in return?

I know gold to others to buy a ship, that is like a given.
