Too Late. I finally took my prior-year ATB qtrs & Prez/N.A. $'s to the bank.
I'd been holding on to some decent examples from rolls & cut up Mint sets from past years in case others need any, but it was time to finally cash them in, given the lack of interest.
So after one last push, I took all my extras to the bank & stopped holding out hope someone might have 2018's to trade in return.
