I think it is up to you to decide what and how you want to collect. The first question is are you a collector or an investor? Up until recently when I added the 70s I kept all prior to 1970. Now I hold on to all prior to 1980 unless it has damage. I keep some 80s and 90s if the grade is high enough. I will keep post 2000 if it is MS. The point is you set your own standards of what you want to keep. If things get to much you can change your methods. No, you are not likely to mass a fortune doing that, but everyone here collects differently. So read the great advice you can get here and do your own thing. I hang on to a lot because I am still learning about varieties and may have some I have not recognized yet. After that I may sort out and spend anything below VF or some other grade.
