PC requested for several items

I've baselined on the sticky thread above, but wanted to doublecheck.
I've listed items and what I think the PC guide lists them at, according to my calculations...

Sundering Hornbow of Marksmanship (max dmg)
Dmg +16% (while hexed)
Armor Penetration +10% (chance 8%)
Marksmanship +1 (18%)
[around 12k or so?]

Sundering Warhammer of Enchanting (max dmg)
Armor Penetration +10% (chance 8%)
Enchantments last 18% longer
[around 10k or so?]

Also, I have a Grim Cesta offhand item
It gives Energy +12 (req 13 death mag)
Improves Casting Speed (10% chance)
What is something like that worth?

Thanks all.

Depends what skin the hornbow is... you might be better off hoping to salvage the Marksmanship mod.

The hammer, without a damage mod is worthless- hope to salvage out the Enchant mod.

The Grim cesta is worth 5k I think.

The horn bow has the bony looking skin (picked up in Abaddon's Mouth).
All items are gold, too, I think I forgot to mention that.
Thanks for the tip on the hammer.

I just picked up another Gold Grim Cesta.
This one is Energy +12, req 9 Curses, Armor +7 while hexed, Blood Magic +1 (15% chance).
Incidentally, this one has a merchant price of 200 gold, while the one above has a merchant price of 376 gold.

2) merchant
3) 1-5k / merchant
4) 1-5k / merchant

Thanks again! I have a hard time figuring out which stuff is what people want and what's worthless.
