On the 2nd link circam posted a cleaner looking 64PL.
Are those luster breaks I'm seeing on the 66PL, and not scuffs ?
Also, comparing the two, I think the 66 should have gotten the DMPL designation.

 

I believe he said the 64 pl looked worse than the coin he had (the 64 that became a 66 pl).

I’m guessing the coin had a combo of luster breaks and some scuffs, but they weren’t bad enough to make the coin a 64. @CircCam can explain it better.

 

Correct, that was posted before the NGC grade came back but the OP coin was way better than the other 64PL I posted.

I graded it 65PL before it got sent out. It’s what I call a chameleon coin though- in some lighting it definitely looks 66PL, in others not so much and the imperfections appear more prominent. It’s a solid PL (moreso than the other I posted for sure) but not DMPL. In my experience DMPL coins have a liquid quality in the fields that is hard to explain but I know it when I see it, and this one isn’t quite there.

You could call this particular coin TPG inconsistency, but IMO it’s equally an example of the fact that grading coins is complex right down to what lighting the coins are being viewed under in the grading room having an effect on how the grade is perceived.

How PCGS missed calling this one PL is another story though and I have to think that one was just human error. The whole grade could have been a mechanical error for all I know.



I know in my field I always say that anyone who says human errors don’t regularly occur is lying to save face. Just google Medical Error statistics in the US for some scary data on that one.

 

I am personally aware of a old fatty blast white Peace Dollar in a NGC holder that went from MS64 to MS67. Sorry, I don't have images so it might not be "proof" to you or others, but it happens.

 

P.S. Depending on the price gap, CAC gold sticker sometimes get cracked and upgraded.

 

They grade millions of coins, of course it will happen. My point was that it is rare, while everyone else seems to want to make the extreme examples out to be common place, they are not.

And old fatty slabs are early generation NGC holders and can be similar to PCGS rattlers with respect to time frame.

 

MS63

 

I see CAC as a double down on your TPG; like a 2nd shot for better grade. Best advice I ever read was buy the coin not the slab. TPG in general is a controversial activity we are forced to with. But for the small collector the costs are high. And that gives an advantage to those with deep pockets.

 

I vote 65 cheek better than 65’s I have. Not sure coin quite there for 66.

Not sure if I like reverse toning can’t decide if plus or minus.
