But let me be clear....I think that the advice and opinion of our veterans here -- regardless of whether they agree or disagree with me (or any other poster) -- is valuable. You don't learn from those who agree with you, you learn from those who point out new stuff or counter your misperceptions or gaps in knowledge.
Uhhhh - there never were any yellow labels. But I do understand your thinking that there were some. Ya see, the green labels were/are infamous for changing color. They all started out being green, but turned various shades of green, yellow and even shades of blue.
No, I think it's blue. We should really create a Sticky at the top of a section with a link to all the PCGS and NGC slabs over the decades.
This was an interesting read. I think the PCGS, NGC, etc. TPG's are a great STARTING point. Just like most things, one should also use their own judgement about the coin(s) before purchasing.
Yup....the thread I created on SAINT GRADING ANOMALIES was really fascinating and Doug's (GDJSMP) comments are really good given that a bunch of coins all had the same grade yet the price varied by over 100%.
I dunno for sure but I think that's a much newer slab. I sold my copy of @Conder101 's book several years ago and I can't recall the specific diagnostics off the top of my head on how to identify all of the green holders. But if you'll look here - https://www.pcgs.com/holders - you'll see that there are quite a few of them. Each one of those has it's own specific diagnostics, found on the obv and rev of each slab, to identify them. There used to be a couple of websites for that but I'm not sure there is anymore. Might be though. There's been quite a few threads here about it over the years. But anytime anybody wants to know for sure, just ask Conder, he's the acknowledged authority on the subject and has been for many years.
Now that you mention it, I think it was him either on CT or another site that did the Slabs Throughout History thread. Thanks, Doug.
I think that PCGS (and NGC?) may have their Slab Histories on their website, which makes things easier.
