Excellent point indeed BKB. I agree with the above years that some coins were inscribed in arabic years instead of cyrillic years. But I disagree with the point that the earlier rubles had smooth edges and it was only in 1718 that the switch was made on edging technology, and this is an example of such:

I really don't agree that arabic numbers are "old ways" but must insist that they are pretty new at that time. Older Peter I coins and such were minted in cyrillic dating.
My point is to say that in the prior years, cyrillic dating was often denoted and this series was the start of arabic dating in regular coinage. In my opinion, the others are just basically one year type coins and they aren't really "regular" coins.
