    When you start thinking you know more than them - it is ego.

    i know how to read the value on the coin and there are a few hundred million people who can do that. maybe we are all egoistic even the new kid on the block kid romeo can read those 10/10 but not our famous friends who we pay 20 and up :rolleyes:

    Apparently you don;t have any idea how slab labeling errors happen. It doesn't have anything to do with the grader spock. It has to do with an $8/hr employee typing on a keyboard.

    Like I keep trying to tell you, you really don't know as much as you think you do. There is a ton to learn.

    And they will correct it if you send it back. But in all of these posts of yours you keep blaming the graders for making the mistakes. They are not ! Yes the company makes mistakes, everybody makes mistakes. My granddaddy used to tell me that if a man doesn't make a mistake once in a while it's because he's not doing anything.

    The folks they have sitting there typing up lables are doing thousands of them a day. Do you really expect them to get every one right ? You never heard of a typo ? You make hundreds of them right here on this site every day.

    The point is you don't make a big deal out of something like that. It's meaningless. And if it is stuff like that that you wish to judge a grading company by, pal you are gonna lose a ton of money.

    Judge the grading companies by the coins and the grades they assign them. And how consistent they are with those grades. And by the service they give you. And that's all.

    just look at the number of typos they make and the number of coins they grade. No one pays me to post here but i pay them for a service. sending coins back doesnt come free it costs money. the graders do make mistakes calling restrike coins proof and proof coins unc unless sits the guy who is the typist deciding what kind of a coin it is. You dont understand it because it doesnt happen to you when you start getting your coins that way then will you truly appreciate it.

    funny how you buy coins for me and i never see them. send it over :D i call that complete absence of TQM. if i submitted 10 coins and 5 came back like that everytime what would you call it. the pop of mistakes that the TPG make for indian coins is statistically significant thats what i am trying to tell you GD

    NGC is numerous times better.

    Ah - now that is the point. That should not be a matter of opinion. It should be measurable.

    It's an extremely low percentage. I've looked at many, many thousands of slabbed coins with almost no typos.

    None of the coins I've sent in came back with typos. Their record is about 500-0.

    Better than my Houston Astros ! :D

    About two years ago(before I knew anything about coins) I bought a 1924 PCGS MS 65 Saint. I took it to my local dealer that showed me some MS63's that looked better. I was thought I was ok because PGGS has a guaranty. I called customer service and was told since I bought the coin on Ebay it the issue was between me and the seller. The guy was pretty rude and the more I pushed the worse it became. Finally he said.........."how is this our problem?" So, so much for thier guaranty!!! Seems too good to be true. Has anyone actually bought what what they felt was an overgraded coin and sent it to PCGS? Are they really going to admit they made a mistake and substitute a properley graded coin or pay you the fair market value difference? If they honored this guaranty, why wouldn't everyone just go to a coin show and buy undergraded coins at a discount and get replacements from PCGS?

    It is. If you think through some experiments, what they look like ?

    The best I come up with is having a "shopping basket" of coins and submit the same coins over and over until you have a large enough sample size. Then look at the numbers. For each individual coin, find the Standard Deviation of the grades it recieved.

    The service with the lowest Standard Deviation is the most consistent.

    I don't know anyone willing to invest the time and especially money, so for me anecdotal evidence will have to do.

    And by that measure, it seems to me NGC is more consistent.

    Ah - but if you have a validated process then they can do spot checks on the output and determine the quality assurance.

    That would mean intercepts a few coins once a week and submitting them through the system and record the results.

    Yes they really do honor their guarantee. So does NGC.



    I think you mean to say over-graded - and you can do it if you want to. I know of some folks who do just that on a regular basis. But you better be good at it - and be right.

    It is measurable, all you have to do is look at the coins to see the truth of it. But it isn't measurable in the way you mean. And that's because coins are not graded with scientific instruments or mathematical precision like drugs are measured and made . They are graded by the human eye and the experience behind that eye.

    So the only way you can measure it is by using your own eyes and your own experience. Then you just have to add up the numbers.

    These tools were brought into play because the human eye was making large mistakes on an industrial scale. Compounding a new drug is not so scientific that it is not subject to human judgments which are faulty and inconsistent, no more so than grading a coin. With experience and knowledge you create mock ups of tableting machinery or raw drug production and then you validate it. And this will probably be done a few times until the mock set up fits within the acceptable guildlines for the agent as defined in the USP.

    Then they scale it UP to full size, and again have to validate it based on assumptions or misconceptions which may or may not be true. And we work out the scaled up for a realtime version by validating the process and re-validating it until in it is completely predictable within a range of error.

    And now you can do quality assurance.

    Now with coins, it is really the same exact thing. You have a grading standard, regardless if it is market based or technical based, it is still a standard. You train people to make grading decisions based on these standards. These graders are NOT supposed to be coin fanatics or experts. They're just trained workers, who might only know how to properly grade one kind of coin, say a Morgan Obverse. When your done with the entire grading process, with maybe a half dozen graders each working on a specific area of expertise, you then take the coins, and put them through the grading system again. If they come out with different grades, then you adjust the standards to create better precision, and retrain the staff. Ultimately then you have a validated process for grading a coin, in this case Morgans.

    Ah, now I have a statistical model to gage my quality on. A few coins a week can be used to assure that my grading system maintains its quality and precision.

    And then you also have hard data to judge the effectiveness of different grading companies.

    It is really not that hard. It really is doable.

    However it will not be done and we will continue to argue about 69's and 70's or ANACS or NCG...

    And it is all ego. There is nothing to the grading skill that can't be taught even to and especially to someone couldn't care less about the coins, and it would be better if it was that case.

    Meanwhile the experts create the standards and sit over quality control, and handle the odd coin that is not within the standards.
