Title: MS Grading scale help
Post by: Oldcoinchest on March 12, 2015, 08:45:57 PM
Hi, sorry if there is already a similar thread, if so can someone direct me, I want to know more about TPG, where does a full scale exist?
So when does a vf 30 or vf40 switch to ef41, or ms60 to au59 etc etc...
I have also seen some abbreviation rb etc.???

If anyone can help a novice in need in the right direction that would be appreciated.

Well I'll have to have a look and see if I can find it but there are other threads about it but what your looking at with RD, RB & BN are used for coppers and it's the colour
RD is what your after and it mean red
RB= red brown 2nd on the list
BN= brown being last

Thanks, I had a look at Eric's site, The confusion I have is where does one grade end to the next, its not clear, does AU start at au53 or au50? does it end at au58 or au59? where does ef start and end? I searched a little bit but couldn't find the full scale, or is the scale on Eric's site the full scale? Is there no ef41, ef42? I just don't know? has to if it is 70 point grading.
The wikapedia link by stevo1962 seems to make a bit more sense. Thanks

Here is every single grade under the PCGS Grading Standard, as well as the individual modifiers.

Although it is a 70 point scale grades aren't given for every single one of them. For example between 60 and 70 there are 11 grade intervals excluding plus grades while in the AU range (50-59) there is 50/53/55 and 58 and it goes from there.

The full 70 point grading system for each number between 1 and 70 is the theoretical application of how the author thought it ought to be implemented. However in practice the circulated grades have been grouped to aid the practical application of the Sheldon System e.g. Theoretical AU56/57s are grouped under AU55 etc.

The full scale as used in the industry is as quoted through Eric's link immediately above my post.
