The tax filing deadline is almost here. Are you confused? Here’s some help…

This tin robot is a working adding machine. He adds and subtracts while his eyes blink and a disc revolves on his head. The 14-inch high toy, called the Answer Game Machine, was made in Japan by Ishida in the early 1960s. It was sold with its original cardboard box for $1,898 by Auction Team Breker, a German auction company that specializes in “technical” antiques like scientific instruments, office machines and cameras.

Robot toys became every kid’s dream in the 1950s and ’60s, when space exploration became a reality. Many imaginative and futuristic tin toys were made, mostly in Japan, where toymakers created space toys modeled on real astronauts, science fiction characters or just their imaginations. Vintage Japanese tin toys originally sold for less than a dollar, but they can be worth hundreds or even thousands of dollars today. A record price of $52,900 was paid at a Morphy auction in 2010 for a tin Target Robot in untouched condition.
