Split year line due to designer mark difference?

Hello

I was adding some Czeck coins to my collection and found the 5 Korun from 1995 har some variation in the designer mark and the year's 5:

Could or should this be differantiated in the yearlines? Split between variant 1 and 2?

Tagging referee: @mk83  & @oldves  for their opinions.

Coin in question:

N#2149

Thank you for the attention to the matter :D

Based on the guidelines I would say there should be separate mintage lines.

Coin varieties and variations

Varieties (also known as variants) are coins of the same type with distinct details … Small design varieties … The varieties can be described in the comment field and they are listed as separate mintage lines.

It would also be helpful to know if this was a transition year between the two styles of designer's mark.  

The 2017 used phor the photo i the listing has the style on the right (b').  Was that used since 1995?
