    Here are the key measures of central tendency ("statistics"), based on Mike's results presented above (Mean = the average grade; Median = the middle grade in a numerically rank-ordered list; Mode = the most common grade):

    Book CGC Grade Distribution Statistics
    # Grade Mean Median Mode
    1 7.0 6.7 6.5 6.5
    2 4.0 4.6 4.5 4.5
    3 6.0 6.2 6.5 6.5
    4 6.5 6.6 6.5 6.5
    5 6.5 7.2 7.5 7.5

    Board members were generally in line with CGC on the Round #1 books.  Here are a a few notable observations, based on the key measures of central tendency reported above:

    • Book #1 (Detective #32): 49% of the contestants were within one grade increment of CGC.  However, taken as a whole, Boardies were a bit tougher on this specimen (6.7 vs 7.0).  The Golden Age bump (especially when it comes to the Batman titles) is a real thing folks!  :preach:
    • Book #2 (Hulk #3): In the Board's collective opinion, this is a 4.5 VG+!  :sumo:
    • Book #3 (Hawkman #1): 60% of the contestants were within one grade increment of CGC.  However, taken as a whole, this time Boardies were a bit more lenient than CGC (6.2 vs 6.0).
    • Book #4 (Batman #248): The "easiest" book for the Board as a whole, with 60% of the contestants within one grade increment of CGC and a mean contestant grade only 0.1 higher than CGC (6.6 vs 6.5).  (worship)
    • Book #5 (Secret Wars #8, Dutch Edn): The "toughest" book for the Board as a whole, with CGC now about 1.5~2 grade increments lower than the Board.  CGC, having the book in hand, obviously saw blemishes/defects that were not readily apparent in the scans.  This reveals an inherent limitation of grading via flat scan.  :cry:

    On a strictly personal note, the thing that surprised me most about the Round #1 books was this: have folks stopped dry cleaning their books prior to submitting them?  hm  These books were filthy!  lol  Over and out for now!  :foryou:  :hi:

    Appreciate the helpful analysis and commentary, Jay!

    the fact that they didn't map era category to the individual listing era is possibly the most egregiously incompetent thing I've ever seen from a billion dollar tech company- I mean it's several orders of magnitude dumb. You don't throw away product attributes and expect all the individual sellers to re-enter the same or similar attributes for 6 million listings just in the comics category.  You map it in the database and run a ----script, not push that responsibility to paying customers and tank all search options, ruins search filters, and royally PO buyers and sellers off all at once. They've broken their own site and made it each individual sellers responsibility to fix when most don't even know what or why or how. Rank amateurs and rank extreme arrogance. I hope they just go out of business.

    Completely agree.  Don't know why they carried the character attribute over but not the era.

    I believe this will really hurt the auction sellers the most.

    Everybody-

    THANK YOU. Had a blast moving these books, and I think you’ll all be happy with them. These had been around here for a while. I certainly didn’t LOSE any bucks on these books, but I’m very happy that i could pass along some solid deals for the folks here on the boards. 
     

    I’ll get totals together in the next 24 hours or so, and the packing process will start as soon as payments are received. 

    Lots of fun - thanks for a great thread!
