double denar 1578 without the Hook – Kettlers Coat of Arms. One picture of coin from http://coins.su/forum/topic/227603-proshu-otsenit-monety-vkl-aleksandr-yagellonchik-polugrosh-sigizmund-i-grosh-polugrosh-sigizmund-ii-dvudenar-stafan-batorii-riga-litva-solid-lignits-brig-prussiya-grosh/?page=2 , next – from collection of my friend. Saw it at first – any comments?

Both coins look very similar or even identical, could be the same die. The crown on the obverse is doubled and seems at the top to be narrower than on the coin with the coat of arms.

Rare variety.
I'm sure that this coins did NOT comes from the same die.
Bright one looks like original, but about this dark I'm not sure.

The most interesting , I found similar in „Lietuvos Didžiosios Kunigaikštystės numizmatika“ by S. Sajauskas and D. Kaubrys, 1993, No. 966, page 182.
But there's mistake in this catalog. It could not came from Vilnius Mint. Lithuanians solved the question about the minting of Lithuanian coins at Grodno Sejm, 1579 only. So,this is the creature of Mitawa Mint.

You are right, there some small differences. The crown itself seems the same, though, so there is a possibility of the same set of punches used to create a die; therefore it would be most likely the same mint/workshop.
