If there is something that I know about,it's the sensibilities of eBay selling. I've done more then enough in my days. There was only one Commodore that I've seen that would have been worth anything close to that, and that was a Commodore Max Machine with a box and two games they had on there.
Anything else like that just makes people jaded, and makes it harder for the rest of us ethical and legitimate sellers to make any money at all. I've had too many people challenge some of my sales on eBay in the past because my stuff was reasonably priced, while the bidders have seen stuff similar to mine for outrageous prices. They assumed my stuff was either a scam, defective.
There is a within reason price. If you have common fare items, sell them at common fair prices. What if someone was stupid enough to actually buy this, or would have (god forbid) bid on this by mistake. Then these people will get all pissy and will tell their friends not to get any item X from eBay because such and such are crooks. Some of the stupidiest people have a lot of friends. The story gets passed around, it changes. Generally that's how eBay selling gets it's bad name and ALL eBay sellers become victims. Just as you don't loot a sinking galleon ship for gold statues to put on the liferaft, you don't try to rake every penny and more from people on line.
