@trickster, sorry for going radio-silent for a little bit.
The surface of your coin may have been whizzed and so that could explain all of those fine lines. As far as being plated or not, that is harder for me to tell. I'm hoping that some others might weigh in as well. To increase the number of people who look at this thread, you could request to the mods that it be moved out of VAMs and into the plain US classic coin area.
