Ukrainian coins

i have a 5 kopiyok from 1992 and one from 2008 and the last has a smaller coat of arms....
same is the 25 kopiyok from 1992 with one from 2006...

could you upload some images here for direct comparison? and then we'll see if we add the data

the one from the left is larger

I agree with Kommodore:
I also have 5 kopyiok from 2004, 2007 and 2008, wich all have a smaller design than older dates.
If you see carefully, there are not only smaller arms: the whole design is far from the rim.

 

will look into it tomorrow. sleeping time
