800-900 dollars.

I have a near mint(w/ manuals) Wind Waker, Skies of Arcadia Legends, Twighlight Princess, Eternal Darkness, SSBM, Paper Mario, Tales of Symonia, and a few others.

edit- Oh ya so I have fire emblem: path of radience....  did not realize it was worth over 100 when I made this thread.....

Should I hold on to these? Will they go up in value?

I think SOA:L will definitly go up. I dont see it getting re-released anytime soon if ever.

I was actually suprised ED only goes for 36 or so with Case and Manual, thought that one would be a tad higher.

I have those and more. I have a pretty big Gamecube collection, about 205 games I believe.

I didn't know they were worth that much!

That's pretty cool, I suggest you hold onto them for now. The older they get, the rarer, and thus a bigger gain. Although if it was me, I would just keep em forever.

Ya I have owned them since I bought them new back when they came out, it would be hard to part with them.... but if I ever get hard up its nice to know I can raise some emergency funds......

I know if those games are factory sealed, they would go for a lot, but thought that once they are opened, they go for a lot... guess I am wrong then

Its almost double in many cases for factory sealed. I have notice w/ manual is a big bump.

First off, nice collection! ;)

I could see Sega possibly doing a VC release of Skies of Arcadia one day.  I mean, you can buy all the Genesis RPGs like Phantasy Star and Shining Force on the Wii Virtual Console today so it seems reasonable that Sega might one day start releasing Dreamcast games.  That said, I don't think a re-release on the Virtual Console is necessarily even a concern for you since Metroid Prime Trilogy is still going for an insane amount of money on Ebay even though it is now dirt cheap on the Wii U eShop.  

In all likelihood all the games you mentioned are all going to continue going up in value even though I would not doubt seeing TP and Paper Mario one day coming out on the eShop.  I'd probably hang on to them just because what you have there are amazing games, but if you're strapped for cash you could definitely make serious dollars especially on Skies of Arcadia and Twilight Princess.

You need to get your hands on Gamecube Component cables. They are the crown jewel of the GCN. Last I checked they are worth up to $200 alone. I love mine.

lol I had those I doubt I threw them away.... need to find....

that said I am suprised they are worth that much. You can play GC games on the Wii perfectly and the component cable for those are easy to find.

This is why i dont collect nintendo at all, not the new stuff or the old. Its always too overpriced
