Not so. If you bought a roll of $0.34 stamps you can still use them; you just have to add additional stamps to bring the amount paid to the current cost of mailing a first-class letter. The USPS will accept the $0.34 stamps that you've already paid for.
In this case, N.H. went from a token-based system to an electronic-based system. You used to be able to buy a roll of 40 tokens for $5.00 and use the tokens in place of quarters at N.H. tollbooths (a 50% discount). Now you have to have an "EZ-Pass" module stuck to your windshield and you only get a 33% discount. This guy already gave N.H. money for the tokens and now N.H. doesn't want to keep their end of the bargain.
There's really no reason that N.H. can't accept the tokens until they're out of the system.
or redeem the monetary value to the man
any other way, it's theft by the state
The toll authority in CT made money hand over fist selling thousands of tokens that never got used, and NYC was pissed off to no end and demanded that the toll authority had to change the token. Since they had no authority to make such a demand, they had to change the subway tokens instead.
