I just got home last night and my $500 box was waiting for me. I took it to Wachovia this morning without issue. They lady was sorta confused, but obviously didn't want to ask any questions. She just said, "I must admit that you're the first person to bring me Mint rolls of the dollar coins." I told her that she'd probably be seeing a lot more of me in the future doing this. She had a perplexed look on her face as she finished up the transaction.
Since that went over without issue, I just put in a 20 box order. My wife is ready to kill me... she doesn't see the value of airline points, I guess (but she does love to use them).
