Clayton,
In a nutshell the Cobb in question has ties to a known person who was known for re-backing Cobb’s or creating forgeries.
Just like with Chan many of these cards end up with collectors who don’t know any better or deep down inside know better but want to believe.
Understandably very few folks would want to admit their pride and joy could be a creation. With the advent of TPG once it’s in a holder it becomes with many folks a hear no evil, see no evil, speak no evil situation.

The fact that the card sold in REA isn’t odd and certainly does not give credibility to any item. REA has sold a fair share of items that have been in question and remain in question also many times items are won back by the forgers themselves when the jig is up or to set values to set up private sales.
Scary out there so be careful and never be afraid to question something, if it walks like a duck and sounds like a duck most likely it’s too late and you’re ducked.
Cheers,
John
P.S. Leon I would be happy to share with you in private but even stated as theory (LOL or Survey) I’m not comfortable at this point mentioning in detail publicly I have my reasons when the time is right you know me not against a public smack down if you will.
The SGC 50 Mathewson Red Hindu was a re-back with no wrinkles FYI. Besides if I take the time to type it all out 9 times out of 10 I get told I'm a dullard who hasn't been doing this since the 80's
