Think a minute -when did the first remote-control robot hit the market? It was way back in 1957 in Japan. This is a Radicon Robot, still in good shape 53 years later. It sold for almost $9,000 on eBay! But it is far from the most expensive collectible antique toy in this list of the 15 Most Expensive Vintage Toys Ever Sold On Ebay.com. Link -Thanks, Danny!
