By forcing their hand and making them either admit they were wrong or put him in jail he has laid the groundwork to sue. And on this issue I think he should. It is common practice by many government agencies to allow the use of "whatever" by citizens untill it is gone or used up. I am specifically referring to EPA regs regarding fertilizers and pesticides/herbicides. After a reg has something removed from public sale whatever is "out there" is commonly allowed to be used until it is all gone without any set time limit.
This principle alone would be enough to base the suite on but I believe there are other examples that are closer to the guys situation. Also, when the Tokens were sold there was no expiration date. It's not like a bus ticket that is sold with an expiration date and time printed on it.
I think the guy can do it and it sounds like he has the will to get in their face.

You mean like the US Post Office? Exactly the same issue as raising the price of a first class letter. Your old stamps aren’t good enough any more.
Unfortunately he may have to pay a ‘NH’ lawyer to succeed!
