You certainly are optimistic, heart_dragon, you will get whatever you manage to sell it for, and if you get $50, that is what you get. But I would agree with Hosman, $1 - $5, if you can find someone who wants it in that condition.
I am sorry to say, but that is the sort of item you would find in a box of other stuff at an Auction, it would definitely not be sold separately.
You could put it on ebay, 99c start, and see what happens, but I think that the postage would be more than anyone would be prepared to pay for the camera, so a garage sale would be a better idea..... Sorry
