The consistency of TPG grading

This question has come up many times over the years
and we have all heard the statements "Oh they graded
tighter in the old days or "Grading is changed to increase
the number of regrades". These statements have all
been denied most energetically by the major TPGs. I have spent
some time and have come uo with some thoughts on the matter.
Developing problem areas have , over time been occurring which
have appeared to be distorting process. these include artificial
toning, excessive cleaning, artificial means of restoring luster, ect.
This can tighten the grading system to become much more selective.
We then have the grading process composed of technical aspects as
well as the component of perception aspects. The barest tightening or
loosening, of the technical aspects can be subtle but cause tweener coin
to increase or decrease by a point. Perception of a coins aesthetic character
does indeed seem to move appreciably over the years. A toned coin years ago
might have graded differently from todays more questioning appraisal. The
setting up of a coin in the way coins are submitted could play an unconscious role
in the graders perceptions of a higher or lower grade. Grading is often subtle and
demanding. I have always suspected that the time of day or the kinds of flow of coins,
could play a subtle role in the perception of the coin.
Thus we have a situation where both the collectors and the TPGs can be correct in their
assertions and yet, changes may indeed occure, in the perception of a coin's grade over
periods of time without the actual technical aspects changing.

I particularly like your point about certain outside influences, like time of day, that may unintentionally affect a grader's views. A grader has just broken up with his girlfriend (okay I'm being hypothetical here) or had a bad lunch or is coming down with a cold. That made me smile.
I do think for the series I collect, the premium placed on old slabs can be overstated and the differences in grading over time is more subtle than some would have you believe. Maybe this is just a function of the truly premium older slabs being picked over already. But it could also be that the shift in grading standards is at times exaggerated.

<< <i>Those of us that have been collecting/buying/selling slabbed coins for over twenty years know grades are not written in stone and grading standards do change and that the same coin submitted three times in a row might come back with three different grades. I remember some guy's submitting coins over and over again until they got the grade they were after. >>
Do the standards change or do the graders change? PCGS likely has published standards for various grades so unless someone can point out where the written standards have been changed, then the standards have not changed. Does failure to adhere to one's standards constitute a change to those standards? Perhaps the reason that a coin can come back different grades from different submissions is because different graders have seen it.
Maybe it is really the coins that are inconsistent. Modern production that is almost always exactly the same should be very consistent. Coins like Morgans that have been around for over 100 years wouldn't necessarily be expected to be consistent. Yet two totally different Morgans can frequently have the same grade.

Nah, sounds like he is honest and mostly right.

Ask my wife.
No, all I'm writing about are greedy people. Ever bought a coin from one of them? I hope not.
I suspect that some submitting a coin hoping for an upgrade are unknowingly sending in a coin that was already resubmitted by someone else and upgraded. Now that mistake gets corrected, the coin goes back to the original grade, and they are unhappy. Tough.

<< <i>My recent experience.... an AU58 crackout came back as genuine. Not a happy camper here. I was hoping for an upgrade and would have been disappointed at a return in AU58. The idea of a genuine never entered my mind. >>
Why not just send it in the holder for a grade review then? Is the thinking that PCGS is less likely to upgrade a coin if they are influenced by the current slab that it is in? Thus, we should crack out for a new, objective opinion?

To those who say don't worry about about the diff between a 63 or 64. Well, if it's my money and I bought the coin raw as a legit 64, I sure as heck won't be happy settling for a 50% loss. In fact I first learned that lesson in 1988 on an 1838-0 dime that I bought raw in a Stacks auction as MS64+...paying $6750. NGC graded the coin MS64 but I felt it had an honest chance to 65. So off it went to PCGS where it graded MS63! Now worth $3000. That was a surprise that I never saw coming considering the number of underbidders I had at the auction. That changed my view of grading forever. In any event back to NGC to try and get it back as a 64. Nope.....it went 65. Now worth $15,000+ as a pop 1. So I should not have been concerned when the coin came back as 63 from PCGS and settled for $3000? After all it's "only" 1 point. Now this was back in the early days when I felt the consistency on grading type coins was as good as it ever got. And with the shift towards moderns the classics have been somewhat overlooked.
Even in the pre-slab days if you bought a coin at auction as MS64 and couldn't convince another person that it was indeed 64, you lost money. 1 point surely makes a difference and TPG's are not needed for that to occur.

If the coin shows wear, how were you expecting a grade higher than AU58?

If we had perfection in grading, there will still be a point where it is a toss up. For example if EVERY Morgan dollar was accurately, somewher there would be a 63 next to a 64 and they would be virtually the same.
Once upon a time there were indeed "standards." It was one of the selling points of the new certified grading system.
If one eliminated all the coins that doubled in price from one grade to the next (such as VF to XF, XF to AU or MS63 to MS64,....) there would be precious few decent coins to collect with nearly everything from MS63-70 removed as well as the VF-AU range effectively gutted for dated and type material. In the case of a Liberty Seated no stars dime, one couldn't even go to Fine since it's 2X the price of a VG. So in that case one could only do Poor-VG and then AU-MS62. If one was geared to AG-Fine and AU55-MS62 coinage this would fit them perfectly. But, everyone else would have to find another hobby.

<< <i>I only have submitted coins to PCGS on two different occasions.... >>
I was shocked to see you post that. I have seen you complain at length about NGC's grading in other threads elsewhere, so am curious as to why you have submitted to PCGS on only two occasions?
