I went through the pop of all my graded cards (the one I could find in the pop report at least; since the Korean Ancient Mew seems to be missing in the PSA-pop; MAP is out of business; and PCA lacks a pop report). I was actually surprised to see how high the pop was for some of the graded cards I own.
