Just minor MD. Coins can't really exhibit "some die doubling" the way they can show "some MD." A doubled die either is or it isn't and every coin struck by that die will show the full doubling for that variety (ignoring matters of die state, which is just splitting hairs). Machine Doubling, on the other hand, takes place during the strike, and can vary from coin to coin struck with the same die.
