Low grade key issues

I don't collect for value as I don't think I would ever sell my collection, but do you think hoarding these lower keys is a waste of money. I don't have any super keys, I guess the Spiderman 129 and I have a Batman Adventures 12, and maybe Batman 232 are my biggest items.

Does anyone else collect lower grades just for the sake of collecting?

Random thoughts while starting my day off at work.

I have a collection where most of the keys that I have are lower grade. I don't have anything quite as rare as you (Amazing Spiderman 252, Secret Wars 8) but my rare/expensive keys are lower graded (Amazing Spiderman 101, Uncanny X-Men 129, Amazing Spiderman 28). Nice to see I am not the only one appreciating the lower quality gems out there :)
