NGC doesn't break out its population of these graded dinars by date and so it just reports 35 including this coin in all conditions.  There are many of these out there with problems, and so are not included in that population.  For example, coins with scratches, rim filing, cleaning, etc. are part of the "Details Grade" population of coins at NGC and that is a much larger population.
