A lot of collectors items are gaudy, but I'm glad these people are saving this stuff from landfills.
I used to have a big old game collection. Games I'd never gotten around to playing, games I'd buy for cheap and flip for profit, games that I didn't enjoy but were valuable, titles I felt should be in every gamer's collection. Modchips, softmods and emulation now allow me to enjoy whatever I want, and I reserve the ritual of popping a game in a console for my most sacred of titles.
Selling off that collection let me focus on the stuff I actually wanted. Trading off a bunch of big-box PC games for one AES title also saves a ton of shelf space, lol.
