alex - your pictures are too small. We can't see the coins well enough to make even an educated guess.
I'm going to say the morgan is fake based on the fact that liberty's head is to small. it shoud extend into the legends on the top and bottom. The third one appears to be a fantasy piece. And seeing how the first and third are obvious fakes we can assume the trade dollar is as well.
All are counterfiet. I think I have an example of each of those here on my desk.....somewhere... haha
