Gratefully Requesting Price Check

As I've progressed further into the game I've come accross a few items, in the past I've let things go for cheap but since the economy is in a state of shift I think money needs to be saved. Speech over.

Fiery Dragon Sword of Defence
Fire DMG 12 - 17 // 8 Swordsmanship
Armor +4

Defensive Air Staff
Energy +10
Light Damage 11-21 // 10 Air Magic
Improves Casting Using Protection Prayers (18%)
Amor + 5

White Sycthe of Giant Slaying
Slashing Dmg 6 - 23 // 7 Axe
dmg +10% vs. Giants

Runic Hammer Of Defence
Blunt dmg 14-25 // 10 Hammer
Dmg +11% // While in Stance
Armor + 4

Jewelled Chakram
Energy +12 // 11 Illusion
Quick Recovery From Blind

Sorry for posting so many, any and all feedback is greatly appreciated, there's a whole bunch more items but I won't have the audacity to post PC's on them, rather I'll see the above as a basis for price judging.

Thanks for reading!

If you manage to salvage the +5 armor head from the air staff, you could sell it for around 5k.

Sadly, the other stuff should get sold to a merchant.

The +4 armor upgrades for weapons can be sold for a few hundred (but check the merchant price on weapons first, if its 150g+ just sell instead of risking salvage).
