so i got all these origional rolls being graded and i cant sell them!! NO ONE WANTS LOW GRADE OR AVERAGE GRADE MS63-64 COINS!!!! what do i do with all this !

Whats the deal...ive been buying origional rolls of half dollars and sending them in to ngc to get graded. getting some fair grades to and now i have all these salbs laying around and no one to sell them to. I tried ebay and im getting less than the slabbing fees for ngc gradded FRANKLINS!! ms 63 fbl ms 64 ms 64fbl and im scared to sell the ms 65's at a loss!!!! now i got three more rolls coming two franklins and one WALKER. walkers didnt grade so good some 61-62-63 and one 64 but i still need to get rid of these coins. ANYONE got any ideas. I like this more than buying collections of raw coins ...i like the higher grades ms 65 -66-67 and want to keep trying to get rolls and having them gradded. BUT WHAT DO I DO WILL ALL THE AVERAGE AND LOW GRADE COINS!!!!!
