I'm in my early 40's now and I'm reaching this same point where I would like to get some of my collection graded. I haven't really considered grading/encapsulating until this year when I was sorting out my collection (somewhere around 25-30 short boxes) and getting some nostalgia from the books that I was looking at. (Tons of sentimental value in these books, good childhood memories, etc). My first submission to CGC is for the upcoming Claremont / Rubenstein events with my Wolverine Mini 1-4. I've started sorting my collection determining what I would like to have signed vs what just needs a press and grade. I'm not looking to offload any of the collection, but to preserve what I have and keep the nostalgia alive.
For the more modern key issues (say everything from 2000 and up) I'm going to submit for a 9.8 prescreen in combination with CCS's prescreen to see if anything can be done. If not, those key's might make it to ebay raw and the funds will be used for 9.8 upgrades.
It's actually been really nice to get time back with the books, even my daughter is getting into it.
