SBA Dollars - To Keep Or Not To Keep - That Is The Question!

I have LARGE bags (many, many, many coins) of SBA dollars that I plucked out of small dollar rolls. I will keep all of the near date 79-P's, 80-S's, 99-P's, 81's, etc. The real question..."Is it worth keeping the higher grade common date SBA's?". I starting sorting them last night into "REGECT" and "KEEPER" bins. The vast majority of coins are 1979-P narrow rim AU-low MS. Almost all of 79-P, D, and S coins are going into the reject bin unless they are flawless. The vast majority of 80-P, D, and S coins are going in the keeper bin (AU and UNC). Damaged or very low grade 80-P, D, and S coins are going in the reject bin. I think all of the 81's and all proofs were already saved when I searched the rolls. At that time, I left some near date 79-P's in the bags just for fun! Another potential question..."Is it worth keeping ALL SBA dollars?" I am not a believer that ALL SBA dollars should be saved in hopes that they will become the next Eisenhower dollar (gone from circulation). But, I thought the question is worth discussing.
