I did the same as confused2. Wisdom isn't much of a guide, as the contents of all chests is roughly equivalent, IIRC.
Gold chest gives money; wood gives a good mage weapon (An Oak or Elm IIRC) the others are weapons too.
None of them are real game changers, so I wouldn't worry about getting a weapon you don't like too much <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
