Two of them are easy to figure out. Just use PCGS and NGC counters and watch them over a period and average their daily changes. Ni believe PCGS is usually around 10k a day and NGC is likely similar. Moderns probably play a big role but grading is grading. Unless it's a show day PCGS and NGC should be around 20k a day if I remeber it right and no idea how much the others would add to that. ANACS probably has decent volume maybe 1-3k a day if I had to guess maybe closer to the 1 then 3 but I doubt the other two combined add any meaningful number to the total. World coins have been hot for both PCGS and NGC as more collectors are looking outside for things to collect and of course the Internet has made them widely available which has added to their volume for sure
I certainly am not an expert on how the TPGs operate, but I find these five-figure estimates of production to be hard to fathom.
It's quite simple how I arrived at my numbers. It's been a while since I checked last, but the last time I did NGC reported they graded 150,000 a month, PCGS 100,000 a month. I did the simple math and divided by 30 to get 8,333 per day just for those two. I rounded to 10k to cover everybody else. That's why my number was too low. But what I should have done was divide by 23 or 24 to exclude weekends and show days when the graders aren't there. So, using 24 just to average things out I now come up with somewhere between 13-14,000 on an average day for coins graded by all TPGs. That sound better ?
PCGS has graded slightly over 1 million per year in their history - 33,000,000+ divided by 30. NGC? Anyone else has to be a tiny fraction of that, judging from table volume at major shows. By the way, PCGS reports that the two most common grades assigned IN THEIR HISTORY are 1) MS69, and 2) MS64. You figure it out. I know why.
Only thing to add to the monthly division method would be pcgs does report some on Saturdays from their counter (much less but usually some which we could argue how accurate that is) and then holidays and shows but over time it does all even out a lot more. I assume NGC probably does some Saturday work as well as needed or just more volume during the week. Bottom line though all methods get us around 10k a day each for PCGS and NGC
Def not mine. I quit submitting to them and started using NGC. 30 calendar days to get my economy orders completed, and $12 less per coin!
If this was the coin world video from the ANA they were being slow as molasses. The data entry they do does no even require graders to look at the screen, it is insanely fast. If you ever walk the halls of a grading company and see stacks and stacks and stacks of monster boxes from just a bout every mint it is quick to realize a couple million a year is plausible.
