Following what appears to be a growing pattern, the 'Terminator' arm prop goes up for auction on July 17th, 2010. The old-school robot arm is assumed to sell for over $15,000!

No one expected this two-foot arm, retrieved all the way back from the 1984 movie, to be worth this much cash.

With the numerous action movies coming out though, it might be a good idea to collect disposed props. You never know how much they could be worth!
