What if!?! CGC had used the 100pt scale over 10pt?

Second what was said above.

 

The first edition of the Overstreet Grading Guide (1990) had two innovations:

 

1) a 100 point grading scale, with gradations in the verbal poor-mint grades (including photos for grade comparisons and listing of how defects (bad centering/white stripe on the cover I believe was "bindery defect 1a") affected grades on otherwise pristine books) and

 

2) the OWL cards (Overstreet Whiteness Level) for PQ designation.

 

So Overstreets was indeed utilizing a 100-point grading scale from 1990-at least 2000 or so.

 

I don't think it would change today's market much. 8.0-10.0 are generally easy to see and grade from the cover alone when slabbed, with grading notes covering hidden defects in the interior.

 

I _still_ have trouble distinguishing among 1.0-4.5, however, particularly with 1.8-2.5. I've only recently begun adding CGC 3.0 comics to my collection, and the variance I see in 3.0s is astounding.

For books scarce in any sort of high grade (most GA), I'm not sure there would be any significant difference in value between an 85 and an 87 copy - with eye appeal being the deciding factor.

 

with Silver and Bronze books you'd probably just end up with more incremental jumps between the new grades above 92, with the only large bumps coming when a 95 or 97 becomes the highest graded copy.

I have always used the concept of "engineering accuracy" so that for books

graded by others between 2.5 and 8.5, I am comfortable if my grade is

in the range TheirGrade-0.5 and TheirGrade+0.5. I consider that range to be

what most collectors would come up with. (Examples: TheirGrade = Fine,

MyGrade = Fine-, Fine, or Fine+; TheirGrade = VG+, MyGrade = VG,

VG+, or VG/F.)

 

At the high end, grades should be the same or off by just one grade level.

 

At the low end, there are too few levels and, I suspect, it is too late to

get any agreement on what numbers should exist. For myself, I use

the following:

 

2.0 = Good

1.8 = Good minus

1.5 = Fair/Good

1.0 = Fair (I include items that are complete except for logo missing here.

I also could include items with a coupon out OR maybe a part of an

ad page out.)

0.9 = Poor/fair (and no less complete than the 1.0 as above.)

0.8 = Poor (and no less complete than the 1.0 as above.)

0.7 = No back cover OR ad page out.

0.6 = No front cover.

0.5 = Coverless or CFO OR one wrap missing.

0.3 = Coverless and CFO OR coverless and first wrap missing.

0.1 = Coverless and more than one CFO OR coverless and more than

one outer wrap missing OR fragments.

 

This is far more detail than anyone else would want but it allows me to easily

tell if one fragment up for sale will merge with my copy to get a complete

copy. Blended copies generally get a 1.5 or 1.8 and go on the list of books

I would like to upgrade if I run across a cheap copy.
