Dude, just stop. You're making a fool of yourself.
"Sports memorabilia people." I assume you are talking about the dealers? You do realize they are not the ones getting ripped off. The consumers are. Manning and other folks within the Giants organization are selling items, they know to be counterfeit, to the fans. Whether it be second hand or directly, they are putting a product on the market that they know is not what it purports to be, so people can spend their hard earned money on it. You know what that is called? Fraud.
And the victims aren't these shady "sports memorabilia" boogiemen that you are now falling back on to admit that you're wrong. Its the person who walks into a sports shop and throws down $1,000+ that they saved up so they can buy a helmet worn by their favorite player. It is little old grandma, who spends her entire social security check to buy her grandson a game used football for his birthday. THOSE are the victims of MANNING'S fraud.
And to pass the buck to "sports memorabilia people" here is disingenuous at best. These are items being sold either to vendors or the consumer directly by the Giants organization. No one has any reason to doubt the authenticity of these items. "Sports memorabilia people" aren't ripping anyone off here. If they are the ones selling this (and it may be the Giants organization directly, I'm not sure), they are merely selling what they have been told, by the team itself, is game used equipment. The Giants are perpetrating fraud. Not "sports memorabilia people." Eli Manning has participated in these fraudulent acts. Not the "sports memorabilia people."
Your attempt to try to pass the buck rather than just say your initial response was wrong is laughable.
