    No, generally not, but from reading your 10+ posts on it without even giving us the actual name of the book itself suggest you just might be. (shrug)

    Cause I asked a general question if there was a rule of thumb on variations of grade by percentagte... if there were no comparable sales.  I used an example.  Wasn't offering the name of the book because there's only 1. And I wasn't asking the value of a specific book.  It's not ten posts.  It's responses to others.  I already found it it's more complicated than I thought thanks for all your insight and help afterwards.

    Tell us the book and grade (pictures if raw) and some folks can give you a sense of how they would value it. 

    It was more of a general question with an example but obviously too many variables obviously.   There's only 1 so I'll come back.to this thread if I run into a wall.  I appreciate all advice.  But as I said above it's cgc 8.0

    You can try to use a different grade as a guestimate at value but it's a very rough calculation.  For mid to low grade books I'll mathematically compare grades, a 6.0 is 3 times more than a 2.0 so a 6.0 is worth maybe, roughly, kinda, probably not but it's a ballpark guess, 3 times more than a 2.0.  For higher grade books I'll multiply by 1.5 for each grade increase, a 9.0 might be worth $1000 so maybe a 9.2 is worth $1500.  

    But none of this takes into account the rarity of the book in higher grade, are there are a fair number of mid to low grade copies and only 1 higher grade copy?  And none of this takes into account the demand for a book, a Roy Rogers book with low demand may not be worth much more in any grade because not many people care while the nicest copy of Suspense #3 might be worth 10 times the next nicest copy because everyone wants it and guys with unlimited funds will pay almost anything for it.

    I'll often also look at other issues in the run to see if there's any recent sales data.  If a 5.0 sold 5 years ago for $1000 and another 5.0 recently sold for $3000 than I can assume all the books in the run increased 3 times value in 5 years.  Or if a book in the run in 5.0 recently sold for $1000 than maybe other books in that area of the run are worth approximately $1000 if they have similar demand and similar demand covers and similar populations.

    There's nothing graded lower, and only 3 books graded higher at 9.6, 9.6, and 9.8.  So...Similar books in same run at 9.6 were selling 230-260.  I think half isn't enough of a discount because those issues were earlier in the run 1 & 5.

    Gold Key books are valuable as a reflection of how long the characters lasted and any pop culture crossover.

    Star Trek and Scooby Doo have the most popularity, and have the most value.

    Dr. Solar and Magnus were revived in the 1990s and have been published by at least 3 publishers since Gold Key, so the earliest (#1) issues from Gold Key are major keys for those characters but not a lot of pop culture crossover.

    A few other Gold Key books have some interest - Green Hornet had Bruce Lee on the cover, Space Ghost and other "cartoon network" characters have cult followings.

    After those types of books, you have to wonder what would drive someone to collect Gold Key issues?  When you can't think of anything in particular, you answer your own question. 

    I own just one Dr. Spektor slab, because it is high grade and contains a Dr. Solar appearance. :foryou:

    I need this!  I have #18 but still searching for 18 and 23. Can't find this book anywhere.

    There are no general rules, it really depends on the census distribution of the book. For things like modern incentive variants that tend to have only 9.8s and 9.6s graded, a 8.0 should be at a steep discount since in most collector's eyes, it is a damaged book. For a Golden Age book, a 9.6 will command an enormous premium over an 8.0 since it could be the highest graded copy of the book with no others even near it. For books with many copies across the grading spectrum, it's easier to guesstimate the value from grades that are slightly higher or lower. I guess this is my long-winded way of saying the value rarely increases linearly. Hope that helps.

     

    Here's the total distribution.  9.8, 9.6, 9.6, 8.0 lol  And there's not raws that appear 8.0 or over...possibly one but it's way way too high and they aren't taking offers.  So forget that and it's been on the market for a couple years.

    no obvious rules.  Most moderns or even bronzes don't sell at 8.0 unless they're super keys.  If you really want to apply a rule, find the age of your book and collect data from books in that era that have plenty of 8.0's and 9.6's that have sold (more data = better applications).  If you're talking about golden age, probably not a ton of 9.6's to compare to.  Do the math (it can be as complicated or simple as you are capable of) for books as similar to the one you're talking about.

    If you want sales history of CGC books, consider using GPA analysis, its a paid subscription service.

    Thanks.  Yeah I looked up and down the entire series with no recent sales in the grade.  It's bronze age. If I could just find a raw book thats around very fine I could figure it out.  At this point I'm spitballing it around 75-85.  Also not sure why this is the grading issue thread.  I didn't think it's the one I clicked on.  There's no way to delete the post huh?

    What are you using to determine comparable sales? If it's eBay, that only looks back 90 days, rarely more. Usually gpa or gocollect will have data in any grade, but will/might require a subscription. 

    The % of value of an 8.0 compared to a 9.6 will be all over the board, depending on the title, or even the specific issue in that title. 

    There's nothing in consensus so no sales at all.  9.6 books in same run are going 220-260...but earlier issues.  After 9.6 8.0 is only other one and there's only one.  Plenty of raws out there but none very fine.  

  8. Is there a general rule of thumb regarding value when comparing CGC comics by grade if there are no comparable sales?  For exampre  if I considered buying a 8.0 CGC book but there have been zero sales.  However there's been a few 9.6 sales of other books in the run selling for obviously a premium.  What would the value difference be between a 9.6 and an 8.0?  I know it's a huge gap but the consensus on some books out there is so slim it's hard to tell.

    I'd go with 7ish. I'd say grading this lands in personal preference. Not a key issue, and what little I know about these books (which are really cool) is that their value drops quite a bit after issue 1, particularly if they aren't pristine. 

    I have a big stack of raws from this run.  Only about 15 of 60 were worth sending.  Was iffy on this one till I looked at the pics.  Just keeping them as readers.

    Dr Spector an similar books are really growing on me✔️‼️

    Me too and seems like potential for a streaming series or movie.  So much content untapped.  It's 4th on my priority of collections.  I want the Solar issues first but either nobody is selling/parting with their 14's and 23's.

    Looks like you might have had a bindery tear at the top of the spine that tore off, so there's a small spine split to go with the spine stress lines. Around a 5.0/5.5 once it's cleaned up & pressed. I'm not that familiar with this book, but I don't see any indication that it's a key comic. The best reasons to grade are significant books, or things that are much higher grade that what would be typical of the era  Looks to me that you can go out and buy a higher grade copy for $20 or less.

    Yeah I figured as much but wasn't 100% sure.  It's not even worth posting for sale. lol  I don't know why I have it but was was stuck between some old Magnus Robot Fighter books that weren't worth grading and some Captain Stern Books.
