    With all due respect Doug,

    The crackout game is evidence of this grade inflation. Population reports are completely undependable because of the crackout game. The number of times I have seen people keep re-submitting coins to get the better slab and actually getting them time and time again to me is evidence of grade inflation. The number of what I call overgraded coins in slabs is growing daily and this to me is also grade inflation. Sometimes evidence of trends is not readily apparent but is bourne out over time.

    Isn't the point about price dependency that AT A GIVEN POINT IN TIME the standards for more expensive coins are looser?

    Thanks, everyone, for all the excellent input. Great thread.

    To make sense of it all, I had to back away from all the details, zoom out, and get the Big Picture. I asked myself the following question :

    Why even have a grade at all ? What's the real purpose ?

    There are many perspectives on that one.

    One important reason is commercial. We need an accurate, widely accepted grade so that two parties can have a reasonable discussion about price.

    So it makes sense to have a system where the many quality factors (surface, wear, strike, luster, etc on obverse / reverse and rim)... all those factors funnel down to one final "overall quality indicator" - and, for a given issue, all coins of that grade will have a similar price - though they may be very different in any single factor.

    That sounds like market grading to me - market oriented, based on technical factors, and a stable analysis method.

    "Market grading" and "technical grading" are NOT mutually exclusive.

    They are like Siamese Twins, joined together. They overlap. Market Grading requires technical talent, and Technical Grading has a commercial "reason for existence".

    Don't get me wrong... I'm not dumbing down numismatics to nothing more than crass commercialism. I have MUCH respect for numismatic scholars; we owe them much. Each of us has a love for the hobby which is non-commercial.

    But in this sport, market forces are dominant factors.

    Mike that's like saying that people going to casinos is evidence that they will win. But the facts are that 97%-98% of the people lose.

    So if coins were upgraded all the time when re-submitted I would go along with you. But they aren't. Fact is, about 90% - 95% of all coins re-submitted are not upgraded, depending on which TPG is being used. Yes, that means that 5% of the coins are upgraded. But of that 5% how many were actually undergraded to begin with ?

    The point is this - they make mistakes, not that many but they make mistakes. They sometimes over-grade and they sometimes under-grade. But most of those mistakes are made with coins that are liners - which means they could go up or they could go down depending upon the decision made by the grader at the time.

    Given that, that is why the crackout game even exist. People love to gamble - just look at how successful casinos are. So they gamble with coins in the grading game. Yeah, they lose 95% or more of the time - just like in a casino. But just the possibility of winning - makes 'em try it one more time ;)

    So no, the crackout game isn't evidence of gradeflation - it's evidence that people love to gamble.

    This thread is great! I feel like I've learned more about grading, but at the same time I'm confused. I guess thats because it comes down to opinions of different people. Hmmmmm... I feel enlightened, yet my head is spinning :)

    Technical grading-any coin with no wear is uncirculated, even if it has huge weak spots and is extremely crude. Coins with extremely flat portraits can still boast grades of Fair to GF
    In market grading, weak striking and crude die etching will greatly reduce the grades of many coins. Market grading is the "net" grade, Techinal is what it really is.

    No Jerome, that is not correct. Market grading and net grading are two different things. A net grade is the reduced grade assigned to a coin because of problems or damage. In other words a coin may have a market grade of MS63, but because it has a big scratch on it the grade of MS63 is reduced to XF45 and the XF45 is the net grade.

    With circulated coins, when they are graded using the technical grading system, the grade is based simply on the amount of wear and any marks on the coin. That's all.

    When grading circulated coins with the market grading system the grade is assigned based on wear, marks, the location of the marks, quality of strike, remaining luster and eye appeal.

    For MS coins graded with the technical system, the only thing that counts is the lack of any wear, the number of marks or lack thereof. Technical grading uses only 3 MS grades - 60, 65 and 70.

    With market grading MS coins have 11 grades, 60 thru 70, and the grade is based upon lack of any wear, the number of marks, location of marks, severity of marks, quality of strike, luster and eye appeal.

    So the TPGs use market grading when they grade coins? Man, I thought it was the other way around. Ya learn something new everyday. This is a really good thread. Sure helps me when I grade coins, gives grading a whole new light in some cases.

    With the exeption of SGS of course, they use only one grade. :D

    See post #17 - "Just for the sake of clarity, there is no TPG that uses technical grading - ever. NGC, PCGS, ANACS, ICG - every single one of them uses market grading and only market grading. So does the ANA."

    I didn't realize that. I thought they used something like a "modified ANA standard" where they took about 99% of the technique from the ANA, and that any differences between them was due more to their individual professional interpretations of the standards.

    Great thread.:thumb:

    Cloud, as an example, if you were to compare the standards that PCGS uses with the ANA standards, you would find that in many cases the PCGS standards are much looser than those of the ANA. But yet both are still market grading systems.

    Now I got a question. I went to the Library today and just checked some books on coins, and read one about coin grading. I forget the title, and unfortunatly didn't check it out, but it said that the major TPGs use both technical and market grading, depending on the coin. Wasn't it said earlier that the TPGs only use Market grading, or did I miss another post? That's what I get for sleeping I guess. Nasty habit. :D

    The book was wrong then. Don't take my word for it -ask them (the TPG's) yourself.

    I disagree, they (the TPG'ers) use technical grading whenever I submit a coin.
    They use market grading whenever someone else submits a coin.
    I know this for a fact and have the slabs to prove it!

    Okay, that's honestly what I figured. I was just double checking to make sure I didn't miss anything. That's all.

    LOL. :D :D :D
