WTB Hammer Grips of [Any Monster] Slaying

I would like to get all of the hammer grips of monster slaying. I don't know how many types there are, but here are ones that I know for sure:

Tengu
Charr
Troll
Undead (I think this is called 'deathbane' rather than 'undead slaying')

I will buy them all, I need one for each of my hammers, so people please sell me them! I know that pretty much no one wants these, so the prices will be fairly low, but it's way better than what you can get from the merchant.

What I will pay:
The gold that I will give for the grips will be computed by the percent damage that the grip does. The formula is [damage]*25

So if you have a grip that does +15%, then I will pay (15*25) = 375 gold.
Here is a chart for you people that don't get it:


Damage | Gold
10% 250
11% 275
12% 300
13% 325
14% 350
15% 375
16% 400
17% 425
18% 450
19% 475
20% 500
