Gerald agrees to cast identify on the cloak and the fancy sword the following day, with the cost of the material components (200 GP for 2 castings) coming out of the loot. (That's already more than the coin). He reports, "The sword is crafted to be slightly better than a mundane weapon and hitting its target, and to hurt a bit more than a normal weapon. The cloak will fortify anyone wearing it against poison, magical attacks, panic-inducing fear, magical efforts at mind control, and a range of similar hazards." (OOC: +1 longsword, +1 cloak of resistance)
Kamdar examines all the loot and decides, to the best of his abilities, that the special items are valued as follows.
buckle: 50 GP
necklace: 75 GP
"An Annotated History of House Thimbrall" book: too esoteric for him to say
assorted books of lesser interest/value: total 55 SP
In addition, simple investigation will establish market prices for the generic items.
+1 longsword of House Thimbrall: 2315 GP
+1 cloak of resistance: 1000 GP
110 arrows: 5.5x1 = 5.5 GP
5 suits of leather armour: 5x10 = 50 GP
5 shortswords: 5x10 = 50 GP
Assuming that is correct, the total is 3551 GP, which could all be sold for 1775.5 GP. The party has a collective debt of 62 GP to cover the identify spells. So each character's proper share is (1775.5-62)/8 = 216.7 GP. Now figure out how you're going to handle the items that people actually want... (And what are you going to do with the Annotated History of House Thimbrall?)
