CAC can roughly determine when PCGS and NGC coins have been certified, using the slab designs and serial numbers as a reference. Is CAC beaning subliminally influenced by these approximate years of certification, given the continuously changing grading (and doctoring) standards? I believe that CAC and everyone else is so unconsciously biased, but I am not a TPG grader and thus solicit their input.

Regarding the above points made about CAC, there are tens of thousands of recently graded coins (high cert numbers) that have CAC stickers.
But here’s my theoretical question - keeping in mind when the TPG first grades a coin, it’s raw, and we sense from PCGS public data that the percentage of coins given plus grades is apparently quite low. When a coin with a CAC is sent back via Reconsideration, this is now the first time that the TPG sees the coin now has the CAC sticker. Does THAT create a subliminal bias towards helping the coin get an upgrade? I don’t know.
If indeed the coin does get an upgrade, even one that was recently graded, it can easily be argued that the coin might be high end. Separately, presumably mainly high end coins are getting sent back in via Reconsideration, hence the upgrade.
It does make one wonder!
