This question is in regards to standards across the board and all third party graders but more specifically to PCGS slabs and the OGH Gen !.2 (1986-1989 ), Gen 2.1 and 2.2 Gen 3.0 and 3.1 (1990-1998) and Gen 4.4 1998-2002 ) In other words would you expect coins in the OGH holders to go up or down ?
I think you're questioning if OGH holders were under graded back then. Maybe as the technology for better glasses improved so did accurate grading. Rumblings about OGH slabs being under graded is possible.
Yes, "across the board" and across time. IMO, looser standards equate to more verbiage and more grades. I have the 1962 Brown & Dunn somewhere. I could jam it into my back pocket. It was very tight but it went in. Know of any current grading guides that you can squeeze into your back pocket?
TPGs exist only to make money, I only use them for authentication. The grades are in general a joke and have never been consistent over time.
I think you'd have to ask this question about specific TPGs and specific time periods. For example PCGS I know purged their entire coin facts imagery because it demonstrated grade inflation, and now it seems they've gone overboard assigning Details grades because they don't want to take risks with their guarantee (or whatever the reasoning is) and have tightened up. ANACS I think also went through a period of overgrading and now they're a point tighter than the other two. To me the "old holders" thing is yet another fad pumping up prices. I can understand the niche of collecting various slab iterations, but not from the standpoint of some perception that they're "undergraded" relative to some other perception of "grade inflation." Why on earth would you pay more for a coin that's more accurately graded?
GDJMSP has definitively stated -- and Insider and other veterans have I believed backed him up on the timeline(s) -- that grading standards got noticeably looser about 2000 or so. I believe we might even have some threads discussing that from pre-Covid. It would depend on the coin, too.
With CACG now on record as taking coins that were as high as MS-65 and giving them DETAILS or AU grades.....I think we are in a pretty good environment right now for grading. We need to see how it shakes out, but it appears CACG is closer to technical grading than modified market grading. A single demerit like rub or friction on a single high point gets you knocked down whereas that wasn't the situation in the past, even with CAC stickering.
Agreed standards did get looser. It will be interesting to see what CAC does in the long run with coin grading. Speculation I heard from some others - CAC green stickers are much harder to get now that they are grading coins. Maybe they prefer you use their grading services. I really kind of do not worry about that - I really do not care about the holder, the green bean, the grader - just the coin inside. I will freely admit sometimes I bid a little more for a really nice coin that has the little green bean. I also admit that sometimes I see a coin (pick any grader) and wonder what the heck were they thinking - and what might they know that I do not.
