PQ coin question

Just an observation i've made from reading the posts around here a while. It seems that most people can't agree on if a coin is a 64 or a 65 but they can still grade within grades. what i mean is that a 64 can be a low 64 a solid 64 or a PQ 64. So what this means is that there is really 30 ms/pf grades right? MS-60low, MS-60solid, and MS60PQ all the way up to 70low, solid, PQ.

    The term PQ means different things to different people. Most experts cannot even agree on the currently used 11 point MS grading scale, much less a 30 point one. Believe me when I tell you that you could show a PQ MS65 coin (in your opiniion) to 20 different dealers at any major show and literally get a myriad of various opinions of grade on it, anywhere from a decent 64, to a high end 66.

  • Yes, but if you ask 5 dealers to grade a coin, average all the grades, take the coin to another 5 dealers, have them grade the coin and average it out, I bet you'll come up with an average that varies by less than half a point of a grade.

  • Adrian.....Good idea in theory but wouldn't grading in 8th's or quarters make more sense? A 63 in:

    . 125
    . 250
    . 385
    . 5
    . 578
    . 675
    . 750?

    Or maybe just grade in half's or quarters?

    .25
    .50
    .75

    Just a thought...... will defer to those more knowledgeable.....With the HUGE price difference in some coins between grades..

    I for one would want to know if it's on the high or low scale of a 65......

  • Its a matter of statistics. If you show a coin to 5 good graders, 40 good graders, or 500 good graders, you are going to come out with an average grade. The bet is that 5 good graders will be within a statistically insignificant margin of a grade. If this margin is above the 50th percentile of a given grade the coin is PQ. At least IMO. Basically if the average is above <gradegiven>.50 its PQ.

    A different way of looking at is, if the coin wa graded by ANACS at an MS66RD and you you saw the coin in an MS67RD holder but were not surprised, its a PQ coin in the 66RD holder.

    I agree with what has been stated previously, but check your math, 3 variations (low, solid and PQ) times 11 grades (60 - 70) will render 33 mint state grades.

    And don't forget on copper coins you also have the qualifiers Rd, RB, and Bn. So for copper you have roughly 100 grades of MS. image
