With all of the botters roaming around, its gotten easier to get most of those items, which in return drops the value of each account down quite a bit.
Ultra Drakath items are worth diddly squat since they're not rare, and easy to get.
Rep Classes put the account value up a small sum, but not too much, pyromancer putting it up the most.
Oracle is a free class, so it adds no value to the account.
Astral Orb Pet puts it up a bit.
Reavers are easier to get now with methods of botting, and with pets so the account value goes up a tiny bit.
The coins arent a huge factor as much as you'd like to think when selling an account, it just adds more "appeal".
16 Achievements, depending on what they are can higher account value, but since you're not listing what they are I can't help you out there.
The Nulgath War "Legacy of Nulgath" Items put your account up more since they're perm rare, and desirable.
Matrix Counduit Katana adds no value.
Random Weapon of Nulgath is partially hard to get, adding a small sum to your account value.
Low Inventory Space amount hurts the account value.
The Level 65 Factor is pretty good, so people don't have to level it, this adds a bit to your account value.
Ascended BLoD adds a good amount to your account value, and so does the ascended blade of awe / blade of awe
Drakath Armor adds a nice amount to your account value.
633 AC's is a low amount, but still adds to your account value.
20 minute boosts add a partial amount to your account value.
Considering this, I'll tally your value(s):
Drakath Armor + 6.00
Ascended Blade of Awe / BLoD + 4.00
Blade of Awe + 1.50
(If you have the regular BLoD): + 5.00
Astral Orb Pet: + 6.00
Ungodly Reavers: + 2.00
All Rep 10 Classes: + 5.00
Pyromancer Class: + 3.00
Legacy of Nulgath: + 10.00
Random Weapon of Nulgath: + 2.00
Level 65: + 1.50
Artifact Hunter (AC / Merge): + 3.00
There's not a lot to go off here, so more information would be nice to have.
