PC on 15% always battlepick

Are battlepicks rare?
Of course not in the realms of sephises, serpents, or the elusive sickle.
But just in general.
What's a battlepick with the following stats worth?

Damage: 6-28 (req. 10 Axe Mastery)
Damage +15%
-10 armour (while attacking)

edit: its -10 armour while attacking, not -5 energy

actually, battle picks are pretty common and one of the least wanted axes XD

so with that in mind... 75k? im not an expert tho lol

Haahhhaaha yeah I was thinking that.
But someone sold it for 15k and I thought that was a bit cheap.
Even the ugliest of all weapons with a inherent 15% damage mod should garner more than 15k I think.
