Photo-Matching

[benjulmag]

Thanks for the response. You may be correct that jerseys are like fingerprints in that they are unique assuming they are manufactured in ordinary due course. By that I mean that when a jersey is manufactured, the manufacturer is not trying to mimic any prior manufactured jersey. But that is not what a forger does. That person does try to exactly replicate a previously made jersey.

Take fingerprints. Yes, everybody's real fingerprints are unique. But suppose I wanted to frame somebody for a crime, and I knew the fingerprints of the person I wanted to frame. Suppose too I had the ability to create finger coverings I could put on that would generate identical fingerprints to this person. In such instance the fingerprints I would leave at the scene by having worn these finger coverings would appear to be those of this other person.

That is how a forger operates with respect to jerseys. He uses known images of the player wearing the jersey to create a replica so precise that one cannot discern the difference with the unaided eye.

So with your Jeter jersey, I am not saying it is not genuine. I would regard photo-matching as step one. If the jerseys did not match, you could stop there and know you had a fake. That is why I use the phrase "negative testing" to describe photo-matching. But having passed step one IMO more is still needed to establish its genuineness.
