In the mid-90s, I became fascinated with toys from my unforgettable 70s and 80s years and amassed a considerable number of action figures (they're not toys, they're action figures!). I did not play with them though, just the joy of being able to find these and display them in the living room gave me enough satisfaction. I even bought some with boxes kept intact because I dreamed that I will be putting up my very own toy shop ten years hence.
Well... it has been ten years. Time does fly when you're having fun! I contemplated about selling some of my action figures because ever since I transferred apartment and had most of my things hauled off to Baguio, my collection has been all over the place. 75% of my display cabinet's glass panels were shattered and so I had to keep most of them in boxes and containers. I still have some of them here in Manila, actually. But early this week, while sorting them out, I can't part with many of them. The Macrosses, the Autobot Jetfires, the Dragonballs, a vintage Voltes V, a Soul of Chokogin Mazinger Z, various Star Wars items, 80s Transformers ... many of these have sentimental value.
These are the ones I will be parting with, though ...
V-Gundam

The various components of this model kit has never been removed from their plastic bags. All decals are present and unapplied.

This kit has metal parts. Though the silver coating has dropped off in some areas, there is no rusting whatsoever.

This is the Soul of Chogokin Mazinger Z Black.

I had the metal body displayed in the cabinet with the original color Mazinger Z. I did not assemble the arms. The only thing I removed from the package is one of the the Hover Pileders which I docked onto his head. The rest of the parts remain sealed and unassembled.

Includes the die cast metal Koji Kabuto figure (below right).
Do you recall the 80s cartoon SilverHawks? I think it was about the same time ThunderCats were shown. I'm selling mine, still sealed in its blister pack.
I Googled this figure and found out that it has become quite a collectible item. Usually, the figure is sold without the box (called loose figure in toy collecting circles), and Tally-Hawk is either not included or sold separately.
This is a more recent acquisition, the super-deformed version of Gundam Wing: Endless Waltz's Heavy Arms.
I had a huge fascination with Macross. The model kit below was one of my purchases which was never assembled. I have a couple of die-cast metal versions which was released in the 80s.
All parts still intact, awaiting assembly. There are some metal components as well.
Lastly, here's the Voltes V De-Classified Book, never opened, although the plastic seal has already torn up at the upper part.

I'm still thinking about where to advertise these to sell... if you're interested though, let me know. I will be advertising them in trade websites soon. Remember, they're not toys... they're action figures!
