We joke, but I think there's some truth to it. Then again, these are rare golden age comics where only one comic in that specific grade is sold once every other year. I am amazed at how many times Heritage will list a Fawcett item now that has 0 previous sales through them (in terms of specific grade and issue).
And yeah, if you check the GPA for Fawcett books sold these past 6 months, quite a few of those are to me. I would rather buy raw, but many of these books that come on the market are slabbed and since there is no premium for these books slabbed, I'll take em.
