cib is only selling around $500 lately. but sealed i'd say easily $1200. definitely something you want to get graded
to answer your other question, sealed makes a huge difference with sega cd and saturn as the game is much less susceptible to disc rot, so having it sealed/graded is a much better act of preservation
Hmm, not exactly sure what you mean by the regular overlap. It looked similar to other sealed sega cd games that I've seen pics of. Has the hang tab on the plastic sealing.
on some of the plastic case sega cd games the wrap prominently overlaps down the back of the box. I'm trying to find an example but coming up empty. Any way it looks like a bunch of them didn't have it so it's probably not an issue.
