vintage Christmas Tree dinner plates, Mt. Clemens pottery holiday dishes?

Set of four holiday dinner plates, 10 1/4" in diameter. These are unmarked, but are Mount Clemens Christmas dinnerware, 80s or early 90s vintage, I think?

These have been used, and have a little bit of wear to the green band border, and some glaze crazing. No chips or cracks or noticeable scratching on any.
