Mr Gimmick Interest check

Hello everyone I have plans to put my Mr Gimmick game to the mercy of E-bay, I just want to check how much interest there is for this apparently rare game (yes I have done my research).

Added several images and a video of the game working. I have to note that the box is NOT original its a reproduction, but the manual is original, it has a small tear at the back (see photo) but except that in good condition.

I seen just the cartridge go for around 500-600$ so I guess with a manual it could go even higher.
I personally LOVE this platformer its one of the best ones out there in my opinion and it is indeed "Nintendo hard"
