On these fake patches in slabs; the grading companies hide behind this nonsense of "we don't authenticate the patches". OK fine. The card was altered in a major way and they didn't detect it. It's the same thing as someone trimming a 7 into a 10.

I believe the Kobe's were created because of reporting in 99 from GameJersey.com were the first creased patch test cards were of Kobe and another UD Employee card

There is a thread on 𝕏 about it under your post from yesterday.

I was shocked the first time I heard that they don't check the patches/swatches. What's even the point then?

The real question with the Farve card is are there any wrong backs? I feel like that would be more popular than a "wrong front."

How do they remove the original patch and replace it with a new one without damaging the card?

What If… the Favre/Tootie error card was from 1991 Upper Deck, Favre was on the front, and there were only a limited number? Let’s say there were only a few hundred copies known to exist, and just a few PSA 10s, that would be cool (not that I’m a Favre fan, just from a hobby perspective).
