MW Heavy Mace (x2) - 624 gp
Morningstar +1 - 2,308 gp
(assuming the weapons labeled as "mace" are also heavy maces)
Heavy Mace +1 - 2,312 gp
Wand of Summon Undead IV - 21,000 gp
+1 Twilight Mithral Chain Shirt - 5,100 gp
Cloak of Charisma +2 - 4,000 gp
(Can't price the "masterwork chain" because it's unclear if it's another chain shirt or chainmail)
2,000 gp in coins
-250 gp for Chrystal's share
Total = 37,094
split treasure as evenly as possible (3-way split between Vana, Morgo and Leofric) = 12,364.67 gp each (or round down to 12,363)
IF "Spawn's Chain" is a MW Chain Shirt, that's +250 gp
ELSE it is a suit of Chainmail valued at 300 gp
IF Chain Shirt = TRUE, THEN total money is 37,344 (effectively paying back Chrystal's share) and split results in a nice 12,448 gp each.
IF Chainmail = TRUE, THEN total money is 37,394 and split results in a less nice 12,464.67 gp each (rounded down to 12,464 presumably).
ETA: If Morgo and Vana both want the Periapt of Wisdom, but neither particularly needs it desperately, perhaps we should roll a die to determine who gets it?
