The problem is that this date dimes comes very nice and MS-66's abound. This means there is an ample supply of nice Gems of the date which distracts from the demand for very high grades.
I can't tell from the photo but my gut tells me you have a nice MS-67 which is too low to warrant the cost of grading. It must have Full Bands to even consider and I can't tell from the photo if it does or not.
Time don't fly, it bounds and leaps.
