What's really confusing for me is that many of these books have doubled, tripled, even quadrupled in a very short period of time, much much shorter than what we've seen historically. As one who came back to the hobby in 2011, and with that additional 10 years of buying, selling, swapping, watching prices, etc., under my belt, I can't justify paying 2-4x more for a book than what it sold for 2 months ago, particularly those books that were formerly realizing a slow but steady increase in that 1k-2k range. It just makes me wonder who is buying those books? Case in point, from my own personal experience - xmen 94 in 9.2. I bought my copy about a year ago for a shade over 1k. Would I buy the same grade now at current price considering you could get one at the beginning of the year for 1500? Not a chance.
