It's unanimous then -- Gerald would definitely favour selling everything (he needs cash more than anything right now), and I can't see why Keth or Jann would disagree.
The one unsuccessful appraise check was on the books; they're worth about 50 SP, so you get 25. Big deal -- 0.25 GP less than previously calculated. Also, I seem to have miscalculated the subtraction by eight, so the actual income for each of you on this adventure is 1713.25/8 = 214.15 GP.
