Mine were worth $552! I sold three of my Transformers today on eBay: Devastator, Omega Supreme and Jetfire. They were in mint condition and, yes, I did play with them. I just took extremely good care of them. We did not have a lot of money growing up so my parents always told us to take very good care of our stuff. So I would play with them and then put them back into their styrofoam cases and then into their boxes.
Yes, I know that means that I am a little crazy, but I am also the one laughing now because I was able to sell them! So Kimmy and I decided that we would buy a Digital SLR camera with the money. Especially since we will be going to Washington state in October for a cruise on the Pacific Catalyst, we wanted a really good camera to capture those memories with. Now I need to decide between a Nikon or a Canon. (Feel free to give me your personal opinion.)
I posted pics below of my old Transformers.
