Sweet GC collection. I don’t think I have a picture of it but I got rid of my GameCube games a few years ago to fund a purchase of a Disney Vacation Club membership. Well worth it. At the time they were worth about $2,800. I kept a Google spreadsheet of everything. I repriced it very recently and it’s valued at about $5,600. It’s doubled in about 3 years and that doesn’t count the systems, component cables, and controllers. Most of which I thankfully kept.
Mine wasn’t quite as nice as yours but I had 121 games including some interactive demo discs. Fire Emblem, Go Go Hypergrind, Gotcha Force, etc... I sold it to a guy in Canada on NintendoAge. I miss some of it and kept a lot of the hardware. I’ve recently started to recollect as many of the games as I can.
