When you check the treasure coffer next to the goblin, he says, " Whoawhoawhoa! If ya's got business wit' da box, ya foist gots business wit' Treasure Coffer. Watcha need?"

Presumably, it's supposed to replace Treasure Coffer with the goblin's name, because the chest is already mentioned earlier in the sentence. It looks like a variable error.

I only checked this with the NPC in Lower Jeuno so far.
