Pre-Jelly Monsters Pac-Man prototype?
For sale HERE. I can't say from the screenshot if this is a regular JM cartridge, or instead a Commodore Japan "original clone". Too expensive of course.

Re: Pre-Jelly Monsters Pac-Man prototype?
For reference, here are two photographs I had saved from the auction.
They show the PCB is a variant of the +3K RAM/Super Expander PCB with two extra TTL ICs. These are most probably used for finer address decoding (the detailed photo shows !A11 and !A12 being made available) - this would allow to use two 2716s in the lower and upper half of a 4 KB address range instead of one 2732 or similarly, two 2732s in place of a 2764.
Out of interest, did a Denial member win that auction perchance and could provide photos of the PCB (component and soldering side) without surrounding cartridge shell? Or does someone else here own a cartridge with the same PCB and could do the same?
