Price check on more uncommon NES items (boxes, manuals)

[Terminusvitae]

I have someone who's offered me a few things that I've been looking for, but I want to make sure it could be a fair deal. This is what I need pricing info about:

Action 52 box
Castlevania 3 box
Dragon Warrior 3 manual
Dragon Warrior 4 box
Dragon Warrior 4 manual

Thank you!

Assuming they're all in decent shape:

Action 52 box: $20-$25.
Castlevania III box: $5.
Dragon Warrior III manual: $6-$9.
Dragon Warrior IV box: $12-$15.
Dragon Warrior IV manual: $8-$10.

Ah-HA! I thought as much.

Thank you very much for your help.
