Thanks Bob, I know there is many books, but sometimes books does not much real life, you know.
That's why I aksed just simple to write dates, after to compair - Books, Mintages, and real life prices. All three togheter should be much different than book's info.
So anybody can tell his opinion? or its hard question?

Well, "opinion" and "real life" don't really go together! I don't trust anyone's opinion too much without hard facts (i.e., statistics, knowledge) to back it up.
I disagree with some of Mr. Kazakov's conclusions (e.g.: why poltina of 1899-(Э.Б) should be rarer than 1901-(A.P) or 1902-(A.P)...

), and why he thinks there is no such thing as 1897-** patterns ("birdies")? He doesn't really explain these things too well.
Still, it is the only reference today with the most varieties. Besides, it is really very well done with beautiful pictures and good examples of edge varieties. And most of his information is quite correct, IMHO.
