well lets try it one more time so you and i agree that a 2008 P and a 2008 D are 2 different coins? next but we have not looked into how a 2008 P coin itself can be different if the dies are worn out and get replaced we acknowledge this in issues like the 1922 no D and the 1955 doubling where we see a visible difference but not otherwise. my proposal is we are making a mistake even 2 coins of hte same year and mintmark cannot be subjected to the same standards if they are made using different dies for the purposes of consistency now this is not very common in the usa but i am studying some coins here where there are 3 bangles on the hand and if the dies are worn the 3 bangles come close together and become a bracelet thus fundamentally altering the design now how should those coin be graded and what are your thoughts on that?
some would say that EVERY evalutaion system is biased or else everything would be equal. I guess it depends on which bias you want to discount and which one you want to value
Actually we don't agree. I do believe the 70 grade exist. The reason most people think it does not exist is because they get hung up on the word perfect. I would agree that perfection does not exist. However, when talking about coin grades, if you take the time to look you will find that the 70 grade is described as theoretically perfect. In other words, it's as close to perfect as you can get. And that you can have. That aside, still curious - if you find this Morgan that has the best strike, and it will be from among the ones I mentioned, what is your best grade going to be ? Is it 69 - 68 ? What ?
But how is the system we have biased ? You take each individual group, date/mint, and you judge them based on the best in that group only. That removes any bias. You only have bias when you judge all of them based on the coins from 1 date and mint. For that is what your composite is going to come down to - a single coin from 1 date and mint.
you're missing the whole concept of a composite... think of the best Morgan you can think of. What does it grade? Does it have flaws? I bet it does. If so, then grade this theoretical coin by it's flaws and you tell me the grade of the best Morgan you have ever seen.
Doug, do we have to go into the definition of what the word "is" means? By definition, in order to compare anything against anything else, you have to have a preference for one thing over another, that's what a bias is.
you have to value certain attributes is what I mean to say. Bias is a word that actually means slanted unfairly, and I don't mean it that way
spock it seems you are making an assumption when you say - "but we have not looked into how a 2008 P coin itself can be different if the dies are worn out and get replaced" That is definitely taken into account when using the system we have. The coins struck with the worn out dies get lower grades. The coins struck with the new replacement dies will get higher grades. The problem you have when you mention the '22 no D is that all of the coins from that date/mint were struck with worn out obverse dies. There are no well struck examples, they simply don't exist. So you judge the coin based on the best examples that do exist. And then you say - "my proposal is we are making a mistake even 2 coins of hte same year and mintmark cannot be subjected to the same standards if they are made using different dies for the purposes of consistency now this is not very common in the usa" Why is it a mistake ? If you use the best example from a given date and mint for your standard, regardless of what set of dies produced it, you are still using the best known as the standard. Are you suggesting that we should now grade coins based on each individual die pair ?
OK, but of you are going to judge all Morgans based on 1 coin only from a given date and mint - knowing full well that no other Morgan from another date and mint will hold up to it for they don't exist because they were struck with lower pressures etc - how can that not be considered to be a biased way of judging ?
I'm not judging against any coin, I am judging against an ideal. and no... we are looking at a coin as a product. something that was manufactured to a standard. You are looking at it as an artifact of a mint for a specific date and year. This is a difference that you will have to abandon in order to see what Paul and I are trying to discuss.
I am tired, and I will talk more of this in the morning. At this rate, I am going to be at 2000 posts by next week. lol goodnight all
Who says they don't exist. They do and one is in auction right now. http://coins.ha.com/common/view_item.php?Sale_No=1121&Lot_No=4956
well then shouldnt the same be applied across years then? what is the difference? all i am saying is there is no consistency. what is the difference otherwise between 2007 and 2008 P cents
But that is where I lose you. You see, coins aren't manufactured like any other product. Different mints had/have different standards, so you can't judge an S mint coin like you do an O. The S mint (lets keep on the Morgan track here) provides a very strong strike, whereas the O mint provdies a weaker strike. Now I know that this is nothing new to you, but what I can't get is why you decide to close your eyes to these facts...?? Speedy
I don't think he's ignoring this fact, Speedy. But to be realistic, the NO mint did indeed strike just as good of coins as any mint to begin with. The problems with weakening strikes arose when they didn't have new dies to use because of the unfortunate business of being such a remote minting facility, and dies were used until their quality was far gone. To a degree, the same thing happend with S minted coins at the time. That isn't a natural phenomenon...that was poor planning and judgement on the Mints part. So why shouldn't they be held accountable for their standards? Guy~
Speedy, we don't ignore those facts. We just want to evaluate them all against each other, not just one date and M/M at a time.
