Thin thick stamp BGS

was told 1st ed BGS graded card will be identified as thick or thin stamped on the label if graded within the last year or 2

Apparently leonhart the youtube guy played a role into changing this to the standard in BGS grading.

I was wondering why my seller had all thin and thick stamps …and was told by them that leonhart and bgs came up with this way of labeling 1st edition pokemon, as of recent, to be the new standard

U hear about this?
