This is a rocking thread

Yeah that makes sense, its always something I was intrigued by. Like what else do people have in their attic, that they don't know what they are sitting on. 

You would still have to test the theory, and everything is based on the last sale. I also don't know who has the copy that would want to part with it.

I'm thinking the best grade copy of Action#1 but I honestly don't know.

Well if you live in Canada (like I do), CLink charges $70 for 1 CGC book... which is insane. (and they only use Fedex so I can't imagine what the custom brokerage fees are...)

First book I won recently (after taking a 10 year break on comic book collecting) I asked them to put it back on sale... No point in paying such shipping charge on a $100 book...

Nice DD btw! 

Thank you.

Yes it was a shocker. I think they're making an extra bit on the shipping. I can't figure one book would cost so much to ship. It appears you need to get multiple wins to make it worth your while.

#2, colour please

I hope they didn't go after passwords.

The asymmetry is that 9.9 and 10 will be some percentage, whatever it is, and 0.5 (and 0.4?) will not have any symmetrical relationship to 9.9 and 10.  Even if you allow for 9.9 and 10 to be "the two possible grades on the extreme high end" and 0.5 and 1.0 to be "the two possible grades on the extreme low end", there's no symmetry between 9.9 and 1.0, and no symmetry between 10 and 0.5.  The shape will basically always be skewed to the "slab-worthy" grades for a particular book or if all copies as "slab-worthy" (such as Amazing Fantasy #15), you'll see a grand total of 5% for all of the grades 10, 9.9, 9.8, 9.6, 9.4, 9.2, 9.0, 8.5, 8.0, and 7.5, and then on the other end, 0.5 will represent 5% all by itself.  No symmetry.

Quoting CGC stats and saying it is asymmetrical because "it is" doesn't really answer the question. Why is the deviation so small, or the skew for the curve so far to the left? If there is a factor that I haven't thought of I'd be happy to say I was wrong or that I missed something.

In the case of modern comics though, I think the factors should warrant a more regular occurrence of those grades.

You're describing a symmetrical bell distribution.

It will not be symmetrical bell for comic books... ever.

What's causing the asymmetry?

In the case of moderns comics, and fair equally balanced grading scale, I would think it should happen with 0.1-1% prob of slabbed books.

You stated that "From a pure stati[sti]cal point of view, grades should roughly reflect a Gaussian curve and those stellar grades should pop up with a known percentage over time."

Here are Gaussian curves:

 

In each case, the median of the curve shows the same volumes on the left and right of the median, relative to the standard deviation from the median.  Therefore, if there is a Gaussian curve for the stellar grades, as you stated, we'll expect some Y% for 9.9 and the same Y% for some other grade Q, and there will be some Z% for CGC 10 (which is 0.1 higher than 9.9) and the same Z% for some other grade which should be Q-0.1 (0.1 lower than Q), and there should be no copies graded Q-0.2 or lower.  Since that's ridiculous no matter where you put the median, and since there is no reason that there won't be tons of CGC 0.5, 1.0, 1.5, etc., graded books regardless of how many CGC 9.9 and CGC 10 there are, there is no reason to expect a Gaussian curve.

I can't believe I have to debate stats after all these years. You're proving my point here. In all cases it's a bell.

3 of the 4 curves indicate proportionality at dead center with varying standard deviation. Let's say the green curve were further to the right, than the left. That could be skewed as in the case where everyone tanked their final, and the prof had to slide the curve over to prevent failures.

What grade are you placing at the center (median) of the curve? 

The median is the chosen middle item of the submitted samples. In every case you should see the semblance of a bell curve. Most samples should hover towards the 50th percentile (top of the bell).

For moderns you will likely see the higher end of the curve only, since most people will submit only the high end items for grading. For older items, you are more likely to see the full shape.

I don't think a 9.9 should be a unicorn. There should be a pattern to their occurrence.

This thread has been done before and I still can't remember. I believe ASM 194 but I honestly can't remember.

The title of this thread should be the title of a comic book. You should trademark it.

From a pure statical point of view, grades should roughly reflect a Gaussian curve and those stellar grades should pop up with a known percentage over time. If not, then those grades reflect something else.

The quality of the process for making a book is pretty impressive for moderns as opposed to the days of pulp. If you buy a 100 unread books and submitted them all, wouldn't you get at least one 9.9?

I finally won an auction for a DD issue that always eluded me. However, I am kind of shocked how much CC takes for shipping. I might not have bothered had I known. I can't remember it being that expensive the last time I won from them.

wow

Don't hold your breath! 

I'm game for the right book 

Maybe some of these Batman's will be in my price range 

Over what, Domino/Deadpool character creation?

Can we get are $1.25 for all those copies he worked on that we can't ever sell anymore?

I was hyped about New 52 and was loyal for quite some time. Then when they decided to rebirth, renumber, then go back to the old number system I was officially done.

I would pick up TPBs online when they become available but I'm not in a rush.

If you don't mind sharing the LCS knowledge,...

1) How much of your sales is on comics, and how much is on other things (games, statues,...)?

2) What percentage of comic sales are on the new stuff as opposed to back issues?
