There are tons of posts about this from the past I remember, but long ago.
The posts earlier seem to pair (numericaly) "UNC" with "MS" with coins, which I think is a GREAT idea, to at least align two parts of currency collecting.
Generaly MS 60, MS 63 and MS 65, and of course the in betweens are used as well for coins. Instead of bogging down the descriptors with all sorts of fancy words, in my opinion, it should be held close to a basic yet differentiating system. Such as GEM, CHOICE and regular UNC (as the adjective). This as a maximum-- otherwise to be honest, I feel that it "mickey mouses" the seriousness right out of the grading scheme (please Dis*ey don't sue me). Earlier I said that CHoice or Gemn should be used but not both, but considering they are both in use now, and IF they can be distinguished and known to collectors WHERE they land in the numerical scheme, then I think the three levels would be appropriate.
As far as other numbers below- a coin is AU 50- AU 59 (generally AU 50 and AU 55- and AU 55 and up is generally AU+)
Then EF40 to EF 49 (EF+ is generally EF-45 or higher)
The same type of system goes al the way down through VF, F, VG, and Good. lol The lowest coin grade I saw was a G-2, and I have owned a note that was even lower (once you put all the three pieces together
)
Notes have followed this grading scale for a long time (and I have no idea how long at this time).
I suggest that we move progressivley with this whole note grading thing, and at least take some steps, BUT to call an AU note as UNC 60 in my opinion is completely wrong. By establishing in writing the proper uses of Choice and Gem, we can avoid a potentially situation that would seemingly dilute the "UNC" market with notes that are not truly UNC (the adjective). If we can nail this one down as an institution, perhaps we can submit it to be included in the catalogue down the road. At least, that way instead of not dealing with the "new grading", we can deal with it, and form it to a way that is already basically consistent with what is already going on, AND have it on paper. We can tackle this early enough before this alternative grading system gets a foothold in the market, at which point there will be ALOT of work to undo to restore order (and credibility) to note grading.
