Sports card collecting

Question for ya: Say a set of cards was released and only 4234 were printed and each set came with 1-2 autographed cards. How many sets do you think people would open and casually enjoy or buy for their kids to have? How many sets would possibly stay sealed in the box? How many sets opened and autos sent in for grading? Players and coaches each got a set of these cards and I doubt they really sleeve any of them after opening. So that's probably 4000 or less box sets for the general public. Topps is sold out already and sealed boxes you can find are in the secondary market. Now here's the other news. It's pro softball cards. Still it's a growing sport and the cards could feature autographed ones from players who played/play professionally and for Team USA. I know someone so I have two boxes that are suppose to be on the way next week. You think the autographed cards are worth grading and maybe keep one box seaIed just because of the limited amount made and they are already sold out from the company who printed them?
Not sure how big of a demand there'd be for that. I guess it couldn't hurt to hold them and grade some.
