Let me see if I got this straight... smoeone correct me if I'm wrong. Grading still to be done by graders (humans). Identification of certain high value coins to be done by a laser scan, to be entered into a database, so that in the event the coin is cracked out and re-submitted, the coin can be positively identified and if altered, the scan will detect this.
The "+" stuff I'm not really concerned with... the marketplace already determines the higher level that PQ or coins with exceptional eye appeal trade at.
If a coin has been expertly doctored already and slabbed, will the laser ID system be able to detect altered surfaces on the already slabbed coin, or will it just map the surface of the coin as an identifier and the coin just gets re-slabbed? If it's unable to detect alterations the human graders have already signed off on, how is this more than just a way to id a certain coin?
As I understand this, the machine will not be doing the actual grading of the coin.. it may serve as a tool to help the graders see certain surface characteristics that may help them grade with increased accuracy, but frankly I can not see a machine grading a coin at least at this point in time, considering grading is so subjective anyhow and as has been said innumerable times before, grading is not an exact science, it is an art.
Please someone point out if I've missed something here... I'm just not seeing the revolutionary aspect of all this, unless there are some proprietary qualities of this laser scan that have not been disclosed which will actually be able to detect surface alterations 100% of the time.

The scan will detect that the coin has been submitted before, and a picture will be displayed to the grader. He will then have to determine if the coin was altered.
"If a coin has been expertly doctored already and slabbed, will the laser ID system be able to detect altered surfaces on the already slabbed coin, or will it just map the surface of the coin as an identifier and the coin just gets re-slabbed?"
The coin just gets mapped; the system is incapable of determining if the surface has been altered. That's the job of the grader.
"If it's unable to detect alterations the human graders have already signed off on, how is this more than just a way to id a certain coin?"
That's all it is, a fingerprinting system for coins (what's done is done).
"As I understand this, the machine will not be doing the actual grading of the coin.. it may serve as a tool to help the graders see certain surface characteristics that may help them grade with increased accuracy,...."
Nope, the system will not aid in the grading process; it can only determine if it has scanned the coin before.

The "revolutionary" aspect is the ability to identify a coin as it comes through the system a second time; thus, giving the graders a chance to see if it has been altered. It also allows them to see the previous grade, so they can confirm an incorrect assessment they made the first time. (How many times have people here shown coins they cracked-out and resubmitted, only to have the grade change by multiple points?)
