So I went into a bank to deposit a check, and asked the teller if she had any halves...
There were two other tellers working, one teller was not helping anyone, and he obliged, giving me $2 worth, of which, one was a 40%er.
Knowing the teller asked only one of the tellers, I waited for the other teller to finish, and asked him if he had any halves... he did!
$11 worth, a roll and 2 loose.
So I opened the roll, and the entire roll was 40%ers ( the two loose were not).
Advice.. if you are going to ask for half dollars (or anything you are looking for), make sure you ask EVERY teller.
