Mint and Proof sets, a stack of them... Should they be graded?

I have Proof sets, Eisenhower Dollars, dated 1776-1976 with the Kennedy half, and the usual shrapnel that accompanies them, [quarter, dime, nickel & penny]. A separate Eisenhower dollar 1973, a mint set 1/4, nickel, dime and two pennies, a 1970 Kennedy half, with 1/4, nickel, dime, one penny. A 1979 set with Kennedy, and an SBA dollar. [2 of those]. And 2 Eisenhower sets from 1973. All remain in the celophane envelopes and have been stored properly since aquisition. HOWEVER, I see, with naked eye, [flaws/marks/toning] and using a huge desk magnifying glass, [sherlock would be proud to use it] gouges, scrapes and nicks reminicent of the bagged coins. (not horribly marred, but still seems to be not 70's. I mean, now, what would be the point in haveing these graded? You can buy these for [at a coin show] for $5 per set. I also have proof sets, these are in plastic, four sets dated 1975, '77. & 2 '78's... The coins are still in the hard lucite displays and in the black boxes, like new directly from the mint. BUT, I have seen these stacked up a mile high on many desks at many coin shows, and none are bringing more than $5 also. I mean hundreds of them. So... the question is, are these worth grading or keeping? 72 USA coins (modern) at what price to grade. (Can I get a volume discount? )

Any advise here would be appreciated, before I use them for pocket change...

Proof sets not in picture, you know what they look like anyway.

PS I sold all those lil proof sets for about face value plus shipping. I kept about three of four of them, just could not put them in circulation or spand them out of pocket. I think someone got a coin collection started and I did not lose anything. I don't know what to do with the others, they are no good to me, so if you know someone who wants their child to start a collection, I will sell them for face value plus shipping. They are the Eisenhower proof sets in plastic. Under $2 face value and I think I have three left.

Just write me for instructions and you can "have" them.
