I'm not a graded card guy (I'm too cheap), but I did find this interesting.
Title of video: "Honus Wagner 1911 -
Restoration and Re-Grade"
Grading terms and condition on SGC website: "7. Customer agrees not to knowingly submit cards to SGC that bear evidence of trimming, recoloring,
restoration or any other form of tampering, or are of questionable authenticity, as determined in the sole judgment of SGC (“Altered Cards”)."
It seems that Kurt is in violation of SGC Terms and Conditions, and actually made it very public
I'm not debating what folks do with their cards. I just found the wording interesting.
