[edit] Doesn't seem quite correct

The history could use some fine-tuning. I recall, for example, most of the numbers and letters in use and consistent prior to 1986, as witnessed by the de facto standard of A Guide Book of United States Coins. (Also, I'm pretty sure than the Guide Book had a larger share of the coin pricing guide market than PCGS had of the coin grading market, so it seems kind of silly to make PCGS sound like the uniter of grade levels rather than the Guide Book.) Also, "MS," "Unc.," and "BU" were eventually indistinguishable due to lack of standards for how "brilliant" brilliant uncirculated was. Anyway, I hope someone who's older and/or has a better grasp of grading history can fill in here. It would also be nice to put in redirects from EF, AU, MS, etc. Calbaer 01:20, 4 January 2007 (UTC)

[edit] Range of scale?

The price range was from $1 to $60, and so the grading range was made from 1 to 70?!!

Since the numbers are different, it would seem that an explanation is in order, or else this is just a typo....

[edit] Basal State

What in the world is basal state? Wikipedia has no article concerning it, and this article references it as if the reader knwos what it means. Mrendo 12:55, 30 January 2007 (UTC)

It seemed fairly clear to me that it was an alternate name for Poor, and the lowest grade on the scale which follows. While I don't know this for certain, I have edited the article to make that meaning more obvious, by throwing in a little more verbiage and using italics to offset each gradation name. If I am in error, would someone please revert my edit? Thanks. -- Eliyahu S Talk 22:36, 11 February 2007 (UTC)


[edit] Non-metric scale

"Thus yet another non-decimal system was born."

That's a highly editorial comment that should be removed

It's also a direct quote from either the Redbook or Photograde. Nibios (talk) 03:19, 2 May 2008 (UTC)

[edit] Grading Scale

It would be nice to include a section that describes in detail what kind of visual differences there would be between MS-63 and MS-64. Perhaps a table that goes grade-by-grade describing a commonly coin, perhaps even with photos of the same coin at each grade. Just a thought. Mwbseiso (talk) 19:38, 9 January 2008 (UTC)
