Here are 2 different charts meant to help a collector measure the same concept: how to assign (a value to) the Grade of a book (from Poor to Mint). It may take a few viewings to reconcile the 2 charts. To assist in "keeping it straight" , both charts use the same major color scheme for the folllowing groupings:

WHY ARE 2 CHARTS NEEDED?
Because "Incremental" grades, as a % or fraction of a NM 9.4 or the perfect "Mint 10.0", do not (comparably) compute as a % or fraction of the NM prices.
Can't a price be set by using the 10.0 chart alone?
The 10 point grading scale causes confusion in pricing, especially mid to lower grade comics.
Example below: a Book may receive a grade of "G/VG" 3.0, but the market price would not approach 30% of the Guide NM price; perhaps closer to 10-15%. A "Fine-Plus 6.5" may market price at 30-33% of the NM Guide price. Without this understanding, you may overpay for a book based on its Overstreet ten-point grade! To learn more about this variance, see Ed's Grading Methodology (click here)
Example: book was graded as a G/VG ; NM $ is $100
OS Grade Scale
As a ratio to NM
3.0
$30 (or 30%) wrong!
Ed's Grade to Price Scale
As a ratio to NM
10-15%
$10-15 correct!
Here is an example as shown in (Ed's) "Beginner's Guide to Grading":
Superman 199 VG+ 4.5, NM = $300
OS Grade Scale 4.5
As a ratio to NM = $135 (or 45%) WRONG!!
Ed's Grade to Price Scale
As a ratio to NM =$60-90 (or 20-30%!) CORRECT!

use this book as a sample: If a NM 9.4 is priced $300+/- and a VG 4.0 price would be $50; the plus+ (in this case, a very vivid cover) adds about $15 (or 5% of $300 NM price!); the book is valued at about $65. FN would be valued at $70-75, so this seems reasonable.
Ed's "Grade to Price" Chart
Use the "Crazy Ed" chart to minimize the discrepancy between grading %'s and pricing $$'s: Ed designed this chart in 1996 as a rule for grading/pricing. (Then, the Overstreet grading guide followed a 100 point scale). Ed continues to use the "scale of 100" because it is simple to convert a grade; 1st to percentages (%) and then, to Dollars ($$)!The notes in this chart (usually highlighted blue) if applied consistently as a tool, help value the "incremental" or "plus" features of a book, can help a collector "fine-tune" the price of a book that falls between grades "Good" and "Fine", and between "Fine" and "Very Fine" or better.
