Thank you very much, Jupke! That clears up my Krause confusion, and I didn't know about that site, it is now bookmarked! I found the auction you mentioned stating 19mm, but a few more auctions down there was one listing the diameter as 18mm! Oh well, I guess between 18 and 19 is good. My coin then has the correct weight and dimension, looks great, and was bought from a reputable source, so I'm not worried about it. It is the common medallic alignment type of the three you mentioned.
Out of curiosity, how did you know your 10 roubles counterfeit was a counterfeit?
