You've encountered what we call "grade rarity".
We can only speculate as to the cause for 1960 dimes,but it is a fact.
In PCGS holders 1960 is the only year in your range for which no coin has been graded higher than MS65. A PCGS graded MS66 would be the finest known and thus quite desirable and valuable.
