Greetings, let me first say that I am very new to these collectables. I have tried to figure out the details concerning this 1984 G1 Trailbreaker that I recieved several years ago as a present from a friend (who's a collector). I failed to realize it's worth until recently, and I am wondering if anyone can give me details on it, including an estimate for what its worth (I am considering selling it). From my own research, I believe it is a G1 Trailbreaker with rub sign. Thanks!
