I am trying to decide whether to send my presidentials in for grading or just buy them graded off ebay

So far there is no pop info on the presidentials. Most of mine do not look like they will grade high. Lucky if I have a 68, probably 67-65. Looks like the 65's are selling for less than the grading fees. I stopped buying state quarters because it is cheaper to buy them graded on ebay. I just bought the 2007 silver quarters set for $65 PCGS PR69DCAM. I can't grade them for that, much less buy them and grade them. Of course I lose the chance to maybe get a PF70. I guess it comes down to...will I get enough 70's to make up the losses on all the lower grades. So far it seems better to buy them graded. The same is true for most of the state quarters. I buy a MS67 for less than the grading fee. Will the presidentials be the same way?

I am interested in what the rest of you think. What is a good grade for the presidentials? Should I bother grading a coin that may be a 65?

just sent this $10 olympic for grading xing my fingers, looks like a 70 to me
