Batman seems like such a big part of childhood that you never stop to think that he's been around since 1939. It's like he's just always been there, destroying the bad guys for us time and time again. It's a testament to his character that he continues to be popular despite the decades rolling by. Batman action figures have been around since the 1940s and have always been wildly popular with the kids.
Though they've been around since the '40s, Batman action figures really hit the big time in the '60s, when Batman's popularity also started to soar. In fact, if you have an action figure from the '60s, you could net up to $15,000 for it! Other characters, including Robin, are worth a lot, too, but not as much as our main man Batman, of course.
