Just what do you mean by "official"
Since there is no government or agency with the power to enforce its standards setting the rules, there are as many "official" guidelines as there are "officials".
- Speedy has posted the ANA standards, which are pretty clear and logical.
- The SGS standards are "If it is identifiable, it's MS70"
- PCGS and NGC each have standards known to their graders and no one else. (They obviously differ in some respects, or coins graded by one would always cross over at the same grade.
) - Other grading companies (real independents like ICGS and wannabees like BACAC - the Beijing Antique Coin Appraisal Center) have their own standards, which vary considerably.
- Most importantly, I have my own standards, which are absolutely controlling For purposes of my collection.
