Answer:
You can place the hold, but it will have to make the funds available the same day they would have been if the hold had been timely placed. If you have lose two days, you have to make the funds available no later than the fifth banking day after you place the hold. And don't forget to send the depositor a notice of the hold.
This will not "cure" the teller's mistake, but it may provide the bank with the protection it would have had if the hold had been placed correctly.
