No actually, I have never heard of a Kelly book. Either you are talking about automobiles or you may be speaking of Don Kelly in Ohio who is a major National Bank Note dealer, and you are referring to the "Standard Catalog of National Bank Notes" by John Hickman and Dean Oakes as the Kelly book?
I am a relative novice when it comes to other areas of coins and paper money such as English hammered silver, classic
US coins, star notes, large size paper money, etc, but when it comes to 1862 $1 notes, I know them 'extremely' well.
There is nothing whatsoever that makes the linked note 'rare'.
