What's a PS4 with PT go for these days?

On quick look, not finding anything over $50, especially as my stuff is mostly second hand and not in mint condition.
I'm a bit disappointed about my old Master System games.

Pokemon XD Gale of Darkness, still boxed and with it's manual.

Fire Emblem path of radiance might be my most valuable one.

According to that website, Rival Schools is up there. Not sure what nutter paid $400 for it though, $90 seems more reasonable but probably lower now the collection is out but not sure if that website knows local currencies as the ebay listings it uses are UK/EU based. Same with Jumping Flash! 2, someone recently apparently got themselves a bargain at £25 which makes me very sad knowing what I paid but it's weird it's not higher for a game that seems so rare.

CEX don't have a single copy of Jumping Flash! 2 yet lists it for £85 but it has several of Rule of Rose but lists that at £320. Guess one is just in more demand.

So many questions, I mean the big box isn't even worth more than £100, when unsealed. This has got to be some kind of special edition right?

Not a physical game but a quick search seemed to put it in the hundreds of dollars range, more valuable than most PS4 consoles without it. 

A cib pal copy of Chibi Robo for the GameCube. It was also a gift from a friend who passed away, so it has sentimental value as well.

Never sell that, mate. But I figure you weren't going to anyway.
