1) Trophy - stated by taxidermist as trophy sold for x gold
2) Cash on hand - added on top of "loot".
3) Loot - Trophy + all inventory items (including preps) with cash value halved, totaled and rounded down (at least thats the closest i've been able to work out).
4) Special (new class / badge and quests) - new class = 50 gold, new badge = 20 gold each
The gold taken in and the prep costs are deducted from kingdom gold when you enter, so you'd have to do the math for net gain, although I can never get it to total up quite right
