Difference between wavebirds

Hi, a local thrift store had a gamecube, a wavebird and Legend of zelda windwaker Kmart exclusive up for sale and i snagged it. Looking at prices online for the wavebird I'm a bit confused. Looks like different colors are worth more. Can someone tell me which one I have and how much its worth? Picture attached. also is the zelda windwaker kmart exclusive worth more or less than the original one? thanks for the help everyone.[attachment=29186:Capture.JPG]

You have the light grey wavebird. I don't think there's anything extra with the game disc. Other than the Kmart logo on the game case, it came with a game guide. As for going rate, it all depends on what a collector is willing to pay for it. I would wait until Kmart goes out of  business before you try and sell it.

Thanks for the info I appreciate it. I hate to sell them but I'm selling off a few things to come up with enough for a switch.

I had that Kmart release.  Only difference (as mentioned) is the cover art.  The official guide was shrinkwrapped to the game, I believe.

In the US, I think there were just the light grey and the Platinum (silver) Wavebirds.  My friend had two of those silver ones, and they flaked off the paint.  (So the grey were the way to go.)
