Well If It is all true, I say a Big Tall tree and a short piece of rope is the fix...

Something the TPG's should do is photograph each coin and keep it in a database. With the computer technology today, they should be able to do a comparison scan to see if they have graded that coin before. I think coins are like fingerprints (especially anything below a 69 grade). Everyone will be diffent. If the FBI can find fingerprints this way, then why can't the TPG's? If they could figure out a way to do this, then the integrity of the population reports would be much higher. But, their profit margins would take a severe hit, so I doubt it will ever happen.  |

I've been harping on this for a while now. The technology exists to just such a thing, in a production environment, but nobody's willing to step forward and make it happen. |

With the technology available to read a coins defects and direction of the grain in the metal and everything, why doesn't someone use that technology to make a computerized grading company. all the graders would have to do is identify things like color. it would probably be more accurate the 99% of graders out there. Send in your coin and they scan it for any off details and depending on strike and wear, they can determine to grade. |

it could probably verify die varieties and fakes too

I guess it would take some reputable person in the coin collecting community to spearhead this, but it may come down to someone willing to take a chance on doing this. I would be all for it and contribute in anyway I could. The current system needs to be improved on. Especially with all the resubmissions going on. That needs to be controlled better.

I already even own the domain for the company. Anybody know where I can get some venture capital?  |

If they can do retinal ID's and Bio Pay ,, the simplicity of scanning a coin for detail is at least 5 year old technology perhaps more.

Using Multi beam sonar I can find a 1/4 inch telephone cable in 2 miles of water so mapping a coins surface is child's play. All it needs is for someone to write the software that defines each grade. I doubt it will happen any time soon as I personally think people will consider a machine incapable of determining a coins appearance/beauty as well as just its technical grade.

Coin collecting and grading is a very personal thing to a lot of people. If they did start using the technology this way, I think some people would not like it, but if it would make for a more consistent grading system, then I think it would be good. As I said earlier, I would like to see this because it would allow us to, eventually, get a more accurate count on some of the coins and their grades that are being resubmitted so many times. I think the people writing the software would have to be pretty aware of what makes a certain grade and what does not. Same with damaged, cleaned and brushed coins, as well as counterfeits. It would be a very interesting project.

If you look at the patents PCGS has patented a coin grading computer system. They even used one on Morgans in the early 90's but they decided it was more trouble than its worth but since they own the patent it seems they would give it a try again since the technology has grown so much since 1990. You can read all their patents on it here Link its pretty cool to look at the images and thumb through all of them (there are like 128 pages of them) to see how it worked, I believe if they tried it today it would do allot better than it did then. Here is a different set of images to thumb through LinkEdited by Susanlynn9 to fix links.  Edited by Bryan1315

The technology to actually do it right is rather more involved than one might first think. The scanning instrument requires micron-level resolution to differentiate between scratches and luster breaks, and this level of resolution comes with the tradeoff of lessened depth-of-field. An instrument capable of both high resolution, and sufficient depth-of-field to accurately survey a high-relief coin, is state-of-the-art even today. Now, further complicating the situation, one must consider speed. The scan must occur in a production environment, quickly enough to make the operation cost-effective and profitable. Then one must consider the intangibles of eye appeal - luster, toning and the like. I believe that an economically-viable implementation exists with today's technology - I've talked to people on the technology end who believe it can be done - but the resulting product will require a sea change in the TPG industry. It is, to me, a shame that PCGS has the process patented, because they have a vested interest in keeping it from the market. |

Yep, it's all about the money. They don't give a rats *** about what's best for the coin community. "Show me the money" is all it is for them. Sad but true.
But I still think it would be great to be able to have pictures of all the coins a company grades so they could cut down on the resubmissions that go on now. That would be my only wish. Just so we could have an accurate count of graded coins.

I fear for all these reasons, we're not gonna see machine (computer) coin grading anytime soon. The top TPGs have too firm a grip on the market and have fought change to the current system for decades.

As Bryan1315 said PCGS had this technology back in 1991 with their Expert System. If fact one of the features they boasted about it was that since it stored the digital fingerprint of each coin, if the coin was resubmitted the system would recognize it. With the advancment in computers since then it could probably do an even better job. Of course that would have ended resubmissions and the crackout game which today is a big part of their revenue. Is there are wonder why it was scraped? Well one reason was that it couldn't grade, but the digital fingerprinting would have still been useful if it hadn't threatened their income.
