impeccable photo quality versus substance

here is a "dilemma" I have been "torn" about for some time now and wondering if others have similar questions to themselves: I have many old photos - going back say about 7-8 years - that I took with a decent (back then) "pocket camera" and depicting good subject matters, but naturally they can't stand up to todays photo technology! but these photos sell quite well at other sites! (they are fine in terms of digital size (8-10-12 Megapixel), is it worth to gamble acceptance (especially considering the recent very stiff "standards") or forget them and be happy that they sell elsewhere (for pennies though)? My angle that keeps me from "gambling" with such submits here is that I don't want to risk the 51% required acceptance rate required by Adobe for handing out the free annual Photoshop subscription! i.e.: I can produce a perfect (near perfect) technical quality, but the substance may not be there (so what's the point of submitting)? I can't possible recreate or duplicate those old photos. any thoughts? Tx.!
