I think you would have done better to part all of that out. Not individually, but in smaller groups. Like collections by console, or something. Every now and then you see someone selling their entire collection like this. But, you don't see people selling just a PS2 collection, or just a 2600 or SNES collection. I would find those more attractive than buying a massive lot of everything. This way you get rid of it in large chunks and people don't just cherry pick your best items and leave you with devalued lots.
Just an idea.
