Webkinz
Webkinz are a plush toy franchise that has a digital component that is fairly new, but they already have a very big and avid collectors base. Recently, a retired Cheeky Dog Webkinz game was sold at the auction website eBay.com for nearly $1,800.
According to a Reuters report, this sale inspired other sellers to start the bidding war for similar games at four figures, and it looks like the demand has grown. Right now, you could go on eBay and find a brand-new Webkinz Cocker Spaniel Dog selling for $1,735. So what are you waiting for? Go find your kids toy boxes and see if you have any Webkinz lying around. They could bring you quite a lot of money.
