26th-Z. I guess I did not make myself clear enough. Combined. As in injection molded plastic around a metal sub frame. That doesn't seem like such a feat. Not mixed. As in mixing plastic and metal. Only an idiot would think that was possible. After more research I found out on my own that they were either metal OR plastic, no metal inside a plastic emblem that could cause a magnet to stick. But thanks for answering my question about the mounting posts.
Thank You siteunseen! No 'acne' here, but a strong magnet sticks and I found no reference to metal inside a plastic emblem. I'm confident it's metal.
