I can see the denomination banner for the Elizabeth 2K on image 1, upper right.
I can see the word "chetirey" (sorry no russian keys on my netbook) on image 2, diagonally from 9 oclock to 12 oclock, so perhaps the fragment you are seeing is where the "2" for the date is, or just below, maybe a piece of flag?
I dont see any baroque elements, or 5K elements, but that doesnt mean they arent under there somewhere.
nice coin.
