Theoretically, if struck by the same die pair, it should. However, flowlines change ever so slightly with every strike. I don't know how sensitive the laser is so I really can't venture a guess as to how well it would perform. Also, I wonder if a laser that sensitive can validate a coin in a holder...especially if the holder is scratched up. For instance, you have an expensive coin in a scratched up NGC holder that's suspected to be a stolen SecurityPlus coin. Could PCGS make a 100% determination without cracking out the coin?
I think this new service is a bunch of bull! That being said, it does have a chance of lasting and even becoming a standard. IF they can perfect some sort of laser grading then it will one day be the standard. And, IF they can pull it off then they should see a huge decrease in their costs and turnaround times. However, all of this will be stifled, IMO, by their greedy attempt to bilk people for an extra ~25% on their already high fee's. So... IF a frog had wings...
But the question now.... is their technology able to tell? I mean is it sensitive enough to distinguish between the two? I agree that no 2 coins are identical... but is their technology able to tell? I'd love to read the trial reports on the devices they are using... I'd like to get stats as to how many coins they have ALREADY run through it. I would think to be safe you would have to run several thousand of the same coin through to make sure that you don't get 2 that have identical "fingerprints"... basically I'd like to know the science.
someone posted a link on the PCGS board to the product I have seen demonstrated several times and that left me with questions the inventor couldn't or wouldn't answer. Seems to me to be the same or similar technology. http://www.coinsecure.com/intro.htm
Couldn't agree with you more jmon. You'll see pretty soon when they come out with "smiley faces" for a new grading standard. Sorry to say but it's just more money in the bank for them. Darn I miss the older grading standard. Soon slabs will be the size of books to hold all the stickers and grading numbers, and lets not forget, the new "+" crapbolla on it...lol
Be interesting if a decade or so from now TPG crash & it will result in relying on our own grading opinions like before.:goofer:
Just reading the thread over on CU, I found another thing I don't really like. The question was asked by Todd: and Don Willis responded: So there goes my idea of trying to cross my NGC coin for a +. It looks like if you already have a coin graded, your taking a big risk if your submitting it for the secure plus program.
I am not bashing CAC CAC has with just a sticker ! Plus all there boasting in the last few weeks in all the coin mags I think Pcgs will be trying to put them out of the coin market with new labels and anything they can do .Ngc will to soon I think both company's are paid to be right not 2nd guessed the Pcgs stock holder thinks the green sticker make there company look bad. Plus the rescission that has been bad for all!
If you mean harsh cleaning - it would definitely change it. If you mean proper cleaning - I doubt it would change anything in regards to the fingerprint. As for toning - that would depend on the toning and the coin. Some toning is heavy/thick enough to cover up some things on coins. So I would have to believe that if a heavily toned coin were scanned/fingerprinted -then dipped - it would be possible that the software would see it as a different coin. But it would also depend on if there was anything being coverd up by the toning. If there wasn't - then it would, or rather should, see it as the same coin. However - proper cleaning and/or the removal of toning can and often does change the grade of a coin. The change can be to the upside or the downside. So theoretically even though a coin could have the same fingerprint - it could have two different grades - and legitimate grades in both cases.
But there is a flaw in your thinking. A 70 coin is not perfect. It is merely as close to perfect as a coin can get. And no 2 coins graded as 70s are 100% indentical to the other.
Dunno if the technology can distinguish between the two or not. But I would think that since my eyes can still distinguish, with the use of a glass, and my eyes are far, far from what they used to be, then it would seem reasonable that this technology should be able to do it as well.
Ok, This is my hypothetical. Take an 1880 S Morgan silver dollar and study it for as long as you would like... say it's graded MS64 by NGC and it's blast white like a lot of 80 S's are for arguments sake. Then take this coin and throw it in a pile of 1,000 NGC MS64 1880 S Morgan silver dollars mix it up. Could you pick your own coin out again? I couldn't. No way. I'm sure you would end up with a hand full of coins that are very very similar even if you memorized the nicks and hits of your coin and would have to guess as to which one is yours... you might be right, you might not be. NGC has graded more then 48,000 coins at that level. My point is that it just takes 2 different coins to show up with the same fingerprint for this whole thing to be a wash. Just how sensitive are the machines??? I haven't seen anything besides a comment by Don Willis to my question that suggest that they have scanned "Tens of thousands" of coins... did any of them show up the same when they shouldn't have? When you are going to use a technology that has the possibility of flagging a coin as stolen these are things that need to be addressed.
No argument Matt. But for all we know those issues have been addressed. I for one can not imagine them going ahead with it if it had not been addressed. I mean they've obviously been planning this for months, probably the past year or longer. Do you really think that a company like PCGS would do something like this if they had not tested the technology ? Believe me, I have no love for the company. My feelings about them should be obvious to all who have read my comments and articles about them over the years. So I am not defending them in any way. Nor am I saying that I in favor of their new "thing". But, the technology for a machine to be able to distinguish one coin from another has existed for some time. And that is the one thing that I have no doubt at all that machines can do better than humans when it comes to coins. No, I still do not think that machines can grade coins. It requires too much abstract thought. But identify them, tell one from the other ? You bet. I can see a machine being able to do that all day long. And do it in a fraction of the time that it would take a human to do it. And yes Matt, I do believe that I could identify a given 1880-S Morgan from among all others. It would require good quality pics of the coin I was searching for, a good glass, and one heck of a lot of time. But I have no doubt at all that I could do it.
I had just read that NGC is doing this as well in cahoots with PCGS. I must have missed that. Doug, I'm sure that you are correct... These guys are not dumb... they do their homework...but I'm just a very facts oriented guy... I'm not seeing a lot of facts presented... just a lot of people saying this works because we say it does. Not to mention they are only going to be scanning one side of the coin for the "fingerprint"
I read this whole thread and see a lot of skepticism and common sense regarding the "new" grading labeling definitions. I only buy "slabbed" coins when I am not comfortable with my own skill in determining the authenticity and quality of the coin; for example, early US commemoratives. I am now convinced that as the new designations hit the market, I, the consumer, am going to pay a higher price for something that has no real base value in relation to the collectability and investment value of the coin. I wonder if these confusing, multiple grading designations and increased costs, passed along to the end consumer, are going to drive people away from the hobby???? just my p.o.v.
