​The one you mention as having no marks, has the NI mark near the rim.

Exactly was checking only under the face value :)
so we have three :
one with 3 marks
one with 2 marks
one with 1 mark

Coins with or without mint mark or/and mintmaster sign aren't other types but they do deserve extra year lines.
I don't see any extra year lines yet. Change request not made yet or not accepted yet?
