We have brought up eBay sellers lock-em-up-bob and samsobo before on this site. They are both eBay sellers who scribble on cheap base cards from the 80's, and sell them all as "signed" on eBay. These are eBay power sellers making thousands upon thousands of dollars based off of an eBay scam.
Both of these seller's use bogus "proof" photos and the power of positive feedback to continue to scam buyers on eBay. Myself and others have brought these forgeries up several times.
Now this alone is no surprise, as we all know eBay is a cesspool of scammers/forgeries. Despite the fact that their entire business is based off of .10 cent base card forgeries, eBay does not care.
Here is where the real problem lies... PSA/DNA is falling for their JUNK. We all know people make mistakes, but PSA/DNA is authenticating and slabbing more and more of these awful forgeries which is a great concern for this hobby. It has become evident to me recently that neither PSA/DNA or JSA have any clue on a lot of athletes. I have pointed out plenty of flatout LAUGHABLE Don Mattingly forgeries authenticated by both "TPAs" recently. It's beyond "mistakes", it's merely a guessing game.
A fellow collector reached out to me and shared some photos he has been archiving on this subject. Ready to spill your morning coffee?
