PC on this gold axe.....

heya people, reletivly new to all this and still havnt got a clue as to what things are worth on guild wars, so i'll post the full stats of it and you can let me know its rough value... cheers

Sundering Gemstone Axe Of Shelter
slashing dam: 6-28 (req 9 axe mastery)
armour +7 (Vs physicl damage)
armour penetration +20% (19% chance)
inscription: "strength and honour"
damage +15% (while health is above 50%)

bought it as an unid axe from someone (wanted my warrior to try axe mastery, only been usin swords up till now)
someone offered me 5k for it this morning, but wanted to use it for a bit first.

anyways, thanks in advance for any help, i'll check back in an hour or so

15-20k~ or so, somewhat common drop in NF

cheers glad i didnt take the 5k now....
