PSA 10 / Low Pop Report Value Sort Feature

All of my cards are currently ungraded.  I am hoping to have a few graded soon, but would love it if there were some guidance as to the best candidates from my collection assuming all are in perfect condition.  I have thousands added to my collection and thousands more to catalog later.  My plan is to have some graded that will be most profitable and easiest to sell so I can then fund additional grading and make more money.  I am a collector and there are several that I do not want to part with, but I have cards of value that I am happy to move if I can get the right price.
