    Ruben-I think the validation is in the fact that people buy these slabs and they continue to buy. They must be doing a good enough job for collectors, otherwise they would go out of business. TPGs are just guides, and like any guide/refrence, affect only a portion of a collectors buying decisions. This is why we say buy the coin not the slab. The end decision is up to each individual and their PERCEIVED value of the coin.

    Ruben, c'mon now. You're too intelligent for this. You know as well as I do that there is no validation and never will be any validation for the grading of coins. It is a subjective process and subjectivity makes statisitcal validation impossible. There - ya happy now ?

    Why in the world you have pressed this subject with such a vengence is beyond me - especially when you knew the answer to begin with. What was it you wanted ? Somebody to say it ? Well, I've said it. Can we stop this nonsense now ?

    I'll let this sit for now, but this wasn't like me saying that one should dip tones coins. :bow: Speedy and I seriously disagree here.

    You happen to make a good point, better than you might know. There has been a lot of studies on market behavior as a predictor of other real events, from election results to baseball scores and beyond. There is something about human behavior as a masses or a crowd in a market condition that promotes remarkably correct results. But it is one thing to predict a result and it is another to construct a result. And of course, the more information that is available, the better the market results.

    That being said, the two things aren't mutually exclusive.

    Actually, you make a good point here. There has to be integrity in the photographer as well.

    Isn't there a company that now does exclusive photo grading?

    If I have posted something that you took as an insult then I am sorry, and want you to know that I didn't mean it that way.


    Your good with google---search it out. CoinWorld and other such people have done more than one grading test and have printed what happened.

    I'm just going to let this sit and return to it some other time. But what Doug said about the process being inherently subjective is exactly what validation is designed to handle. It measures subjective forces and allows you to create processes that correct for them, and to minimize them. It would be used, for example, when building roads and determining traffic patterns. It is used to measure root cause analysis of medical errors, and so on.

    Yeah, well, aside from being happily in the upper 5 percentile, 96 percent of Cointalk, until know, isn't about debating.
