One way of figuring this out is to do this mathematically. It is based on the CAC and PCGS definitions of their grades.
CAC stickered is:
.4 through .3 of the next grade higher.
whereas I believe PCGS is .70 through .99 of the grade.
This means that
.4 .5 and .6 of the grade, CAC is below the PCGS + grade (3 of 10 or 30%)
.7 .8 and .9 of the grade, CAC is at the PCGS + grade (3 of 10 or 30%)
.0 .1 .2 and .3 of the next higher grade, CAC is above the PCGS + grade (4 of 10 or 40%)
In reality, probably more than 3/4 of all coins graded by PCGS as .0 of the grade would no longer go to the higher grade any longer and would be downgraded to the lower + grade???
So based on the above, assuming all coins are evenly dispersed among all fractional segments of each grade, it would appear that 70% of all CAC stickered slabs should qualify for the PCGS + grade.
Another even simpler mathematical way to devise an answer is that CAC grades their stickered coins as A or B coins. If their split is 50/50 then since only the A coins qualify for the PCGS + grade, then 50% of the CAC stickered slabs should qualify for the PCGS + grade.
Of course, based on the above two mathematical models, the answer could range from 50% to 70%. But in reality, the % is probably closer to 30% to 50% because some of the CAC stickered coins actually qualify for the next higher PCGS grade.
Depending on the actual fractional grade dispersion the actual % will vary.
