Lithuanian denier? Help with identification needed

Hi

This tiny coin seems to be from Lithuania however I can't find a reference. 

It's 0.27g, 12mm

It is not Lithuanian. We do not have cross on the shield with dots as coat of arms.

 Norway is my guess - with a crowned Gothic N letter in a circle of dots. 

I've checked whole Norway with filtering 0-0.5g.

No success unfortunately….

This is from the Principality of Kiev

N#166222

Much rarer than any Lithuanian denier, nice piece

Thank You so much for helping me on this. 

Indeed, very nice coin, especially that it's pretty rare :)
