Dave - grading banknotes (or coins for that matter) is very subjective. One collector's opinion might differ greatly from another and without the banknotes in-hand it is not even fair to suggest a grade. See this link:-http://www.coins-and-banknotes.com/...v-sedler.php
The signature combinations to which you are referring means that if you have a set of 100 ruble notes with the Bank President Shipov and a minimum of 12 of the 13 cashier signatures your collection becomes more valuable. You already have two - so only 10 more to go!!
The notes that you attached to your post do not appear to have any creases, stains or wearing (cuts, crumpled edges etc) so they may not have been circulated but without actually seeing them in-hand it is hard to say.
Price lists as on the ATS website will give you an idea of the value but, as Fioti says, checkout the eBay completed auctions to see the price and condition of final sales. Hope this helps!
