Italian collector Alessandro Claudia put up one of the largest portable gaming collections I've ever seen up for auction (GameSniped believes it's "the biggest handheld collection ever surfaced on eBay".), offering 600 vintage handheld and tabletop electronic games -- from Acetronic's Chess Traveller to Yonezawa's Sicom 16.

The starting bid for the now-ended auction was a jaw-dropping $35,000. Alessandro doesn't expect to actually sell off his stockpile for that much; he's using the eBay listing to publicize that he's selling his 620+ games individually, accepting any reasonable offers for the titles. Most of the games are boxed and complete, and the collection includes a few unique and rare items.

The seller says he's abandoning this hobby due to undisclosed "personal reasons"; it's worth noting that he didn't start amassing this impressive collection until just three years ago! You can see photos for each of the games and read about how Alessandro's preserved them on his site.
