Has This Been Done Yet?

It would be very helpful to be able to look at hign rez photographs of coins that have been graded by a first rate company like PCGS to learn how to grade well especially in differentiating between the subtleties between grades. For example, looking at 15 or 20 Franklin half dollars of MS63 quality then 15 or 20 of MS 64 quality, all by PCGS, would greatly aid in learning about grading.

One of the problems with grading books is that you only see one picture of each grade (if that many). Two MS63's may look entirely different scratch and tone wise but still be MS63. It is the ability to spot a grade from a diversity of coins that is the master's level of grading.

So here is the question. Is there a database of images from previous grading that can be accessed in order to compare. The more images of a particular grade there are the more it solidifies the standard for that grade. It's very much like case law in the legal system. The more case law that is documented on a particular subject the more that subject is rendered "settled" as far as precedent and future legal considerations.

If there is no database, why cant there be one?
