For those that didn't see/read it, I did this little experiment just a short time ago. (These were purchased already graded)
2 were recent/newly graded, which was a surprise to me as I always found older graded to be graded less harsh. From what I have seen lately, PSA has lessened/lowered their standard or they are screwing up bad lately.

Regardless, none of my cards will be sent to PSA anytime soon.
