Price check: A few MSX titles

[Evilhead]

Hiya!

I was rummaging through a friend's attic and found this small box full of MSX games. Most of these are tapes but there are few cartridges as well.
Some of these have been seen on ebay and other places, but there are few that I couldn't find, and would like to have some info about actual value of these items:

-Knight Orc CiB (3 tapes, manual, box and some hint request slip)
-Maze of Galious L (cartridge)
-Arkanoid (tape, CiB)
-F-1 Spirit CiB cartridge
-Jump Jet CiB tape
-Winter Games CiB tape
-Shark Hunter CiB tape
-Boulder Dash CiB tape
-Mappy CiB tape
-Mazes Unlimited CiB tape
-Wizard's Lair CiB tape
-Tank CiB tape
-Turmoil CiB tape
-North Sea Helicopter L tape
-Master Games (includes 4 Ultimate-games: Gunfright, Nightshade, Alien 8 and Knight Lore) CiB tape
-Pitfall 2: Lost Caverns CiB tape
-Vestron L tape
-Galaga CiB tape
-Octagon Squad L tape
-Howard the Duck CiB tape
-The Hobbit L tape
-Army Moves L tape
-Elite: Gold Edition CiB tape (Includes ship identification chart and short novel titled "Dark Wheel")

There it is. If I could get some value for even some of these, it would be greatly appreciated. I found many places with information of these, but nothing regarding their rarity.

Thanks in advance, folks!
