I wonder why it has taken so long for some one to use computers to grade coins. I would think there will need to be a mix of computer/human grading to accurately capture some of the more subtle nuances in coin "beauty and value" that people perceive can only be hugeeyes "seen" by humans. After all the true value is not necessarily what is printed but what appeals to the collector/buyer eye!

Eye appeal is still in the eye of the beholder.

A standardized set of rules means a grade may be based on whether a coin has 65 "nicks" or 66 "nicks". "Beauty" of tone is not held by all. "Old cleaning" or "Lightly cleaned" and retoned will simply be ignored or everything will be "Cleaned." So, combined, an existing grade may drop and that leads to a lack of public support.

Coin grading is subjective, the rules are very loose, and the customers count on that aspect, a lot. Many coins currently graded will fall into the realm of "cleaned", "corroded" or "damaged" if the program is accurate. As a result, I think it unlikely to succeed in the computerized realm, even though it may be more consistent and accurate.

Actually, programs are advanced enough now that they can learn or be taught which coins have the best eye appeal since it's going to be based on light reflection and refraction, colors scales and such that's known to be most pleasing to the human eye.

Plus, people overrate eye appeal in grading, the grading companies looks more at wear, contact marks, distracting marks, and eds, mds, and lds. I have seen plenty of ugly coins get a gem grade when they were not as nice as an MS64.

It would downgrade some of these bulk dealer condition grade rarities and stop the market grading for certain. I would finally obtain the next valuable grade as will many other small time submitters who tend to know how to grade. It would slowly begin to erode their precious value guides of coins in their holders because the TPGs would not be able to control the pops.

It would also cost them money as well since resubmitting to "buy" a higher grade would cease.

Daniel, I agree. Mark makes some good points also. But.....
There is a lot of comment on CH and elsewhere about the ambiguity and inconsistency of the current grading companies decisions. Dealers/ sellers like the companies that grade higher (for resale). Some coin sellers ("salespeople") rely on the human element of grading to keep the buying public insecure and in the dark about how to properly grade and therefore value coins. Consistent grading should be the norm. We have all griped about liking this or not liking that grading service for many different reasons, probably all valid.
Anything that can be done to give confidence to the collector that the coin they are considering is accurately graded (and valued) is a good thing. The collector still needs to be able to make an informed decision. Like everything else humans are involved in there will still be those individuals that will put more energy into deception because of greed or boredom.
Humans still need to make the final yea or nay decision over the computers for many reasons (can you say "We've been hacked" everyone).
I imagine there was a lot of similar doubt, resistance and conversation when grading companies first came on the scene. Why did ANACS first start encapsulating and grading? To eliminate grading irregularities? For the benefit of collecting?
