Over/Under Grading By TPG's.

BLUEJAYWAYBLUEJAYWAY Posts: 9,636 ✭✭✭✭✭

I've read here from time to time that this does in fact exist. It exists on the sports card side as well. Probably to some degree with any collectible grading service. So what can be done to balance the sometimes uneven scales? Does this lack of continuity mostly apply to "bargain basement" TPG's? If in fact grading is just an opinion can yours be better at times than a grading service?

  • Sometimes a coin can be undergraded, sometimes over graded

    I once read an article in a psychological journal. A judge handed out more jail sentences and longer ones at that if he hadn’t had his lunch, after eating he was more lenient in sentencing

    Same applies to coin grading undoubtedly. We are all human and I’m sure more factors than can be listed here come into play

    I’ve sent quite a few pcgs coins in for reconsideration and got a higher grade

    I suppose your grading could definitely be better at times, and I know people who’s grading on certain coins is trust more than pcgs

    The top three things you can do, in order of importance:

    1) Learn to grade.
    2) Learn to grade.
    3) Learn to grade.

    Seriously, though!

    Coin grading is an opinion rendered by trained, experienced individuals - but still an opinion. There are no standards, just general guidelines. The over/under situation exists, but not to the extent many think. The graders opinion can, and has been, challenged - sometimes successfully. Formal, measurable, repeatable standards will need to be developed and implemented in order to eliminate this small area of dispute. Cheers, RickO

    In college, I worked at a fine dining restaurant near a Federal courthouse. Twice a week, the judge would come in and slam a two martini lunch. Never did figure out if that was better or worse for the afternoon defendants.

    A dealer I know swears that Anacs undergrades Morgan dollars on bulk submissions. It all depends on who is doing the grading and the finalizer.

    Everything you said is exactly true. That's why it is important for someone who is purchasing coins to be able to judge grade for themselves...

    The tpg (pcgs and ngc) are considered the best in the industry which is why coins graded by them pull the biggest dollars. The other companies are considered less reliable by the industry, as such they pull less dollars. More reliable doesn't mean infallible though.

    As was said above the only way to protect yourself is to learn to grade yourself.

  • Most of the time the major TPGs are accurate. They have more than one person grade each coin, and a finalizer to review the grade before the coin is sealed in the holder. That said, they are all human and occasionally over or undergrade a coin.

    An opinion is an opinion. Not guaranteed for all to agree.

    Have there been any studies conducted on relative grading between the TPG's? something like taking one coin, submitting it to ANACS, cracking it out and then sending the same coin to NGC, and finally, cracking it out again and send it to PCGS?

    I'm not sure you could draw any conclusions from one coin as it would probably take several coins, different series, different grades, and could get quite expensive.

    Would be an interesting study and interesting to see the results.
