I've been following this YouTuber that goes by NE Ohio Sports Cards. He believes one of the reasons we've been seeing so much appreciation in the graded comic book market is largely due to sports card investors entering into the market. He made an interesting point by comparing how comic collectors and sports card collectors views differ when it comes to CGC graded census count. For example, a NM 98 in a 9.8 with its 3k+ census count may seem like a lot to us (comic collectors), but to the sports card collectors, 3k+ is nothing. Sports card investors comes from an environment where there are 5k or 10k+ for a particular rookie / PSA 10 card. When they look at the prices compared to the census counts, graded books all feels cheap to them.
What do you guys think?
Here's a recent video of his:
