The problem is perhaps a bit more complicated than it seems. Pre-1917 Russian numismatists of course understood overdates but did not pay a great deal of attention to them. In their work covering 18011904 Giel & Ilyin put an asterisk (*) besides a listing where some special difference was known (such as an overdate, but also including overmintmaster initials, etc.) but nothing further. In the work covering 17251801, however, Ilyin & Tolstoy simply ignored overdates, probably due to a lack of time and the large number of overdates to be found.
Although much of the yeoman work on the corpus volumes was done by others (e.g. Christian Giel) the Grand Duke put his name on the finished product and must bear responsibility for mistakes. However, in all fairness, errors in the corpus volumes are few and far between and the work must stand as one of the most outstanding achievements of pre-World War I numismatics for all countries.
The Chaudoir illustrations are well known for their accuracy and the fact that the overdate 1786 pieces did not match the 1837 drawing must have been a serious consideration in Giels decision to exclude the 1786/5 coinage from the corpus.

Dear RWJ, thank you for your time and answers.
Somewhere in "Staraya Moneta" magazine published in St. Petersburg in early 1900s is an article study of Russian Rubles of early to middle 19-th century. For some dates there described over 100 variations up to smallest details in leaves, berries, all overdates, overmintmasters, etc. so I assume that at that time numismatists paid enough attention to overdates (and details overall). It was also because many coins were relatively cheap and available for study and comparisons.
I do not know what can support the statement that Giel, Grand Duke himself or whoever wrote that particular statement (that 1786 coin does not exist) for Grand Duke's book had never seen that 1786/5 coin. This seems very unlikely to me. And I do not know why you think that the statement in Grand Duke's book is a mistake?
It does seem to be a complicated issue, there is no straight answer to weather 1786/5 coin exists or that is just how last digit of 1785 coin looks. Opinions differ as I see, you state that it exists, LC (for example) states that it's just 1785 coin (see his statement above) and I do not know what is true and what is not.
I tried to dig somewhat into the books that I have but there is no straight answers, in fact most books deny existence of such a coin.
