Has Anyone Dealt with Project 2013B?

Yesterday I received an email from what was formally the Zegers/Winograd Project informing me that I have a potential matching pair while requesting images of my note. In turn, I submitted the images as requested, and I was informed earlier today that my note is part of a verified matching pair. I don't buy their pie-in-the-sky estimates of $15k, as auction records beg to differ. That said, I was wondering if any of you have ever dealt with a comparable situation or have any experience with the process.
Here's the note in question:

I have submitted a note myself but there has not been a match identified as of yet. From what I’ve read there has almost been as much difficulty getting the two people with the matched pair to agree upon a price for one person to sell the note to the other as there has been finding a match.
As far as a valuation goes, I’ll let our more knowledgeable forum members provide their insight since this is outside my wheelhouse.
Personally and respectfully, if I had a match and another person had a match, I wouldn’t pay more than $750 for their note. Maybe it’s me, but I’m just not impressed with these pairs.
I have entered many, no match notifications yet. Stars got to align for a jackpot. Condition of both notes, perceived value by each party and who's selling to whom. Should be interesting. Good luck.

Please forgive my newbie question, but what is a matching pair? I have collected coins for many years, but I'm pretty new with currency.

This has some good info.
Na, it smells like a "pump and dump" scheme.
