I have two, 3964xxx and 3993xxx. The 364 is chrome and not coded. The rear element is coated but appears thinner coating , more transparent , and with a green cast. 399 is black, weighs less, factory coded, and has a heavy blue coding like you would see on older lenses.
Maybe the 396 was a multicoated which look different than single. It would be easy to mistake for not coated.
