I have to believe the less people who handles the coins, the better. Too many tellers know about silver and it disappears before you can get to it. I prefer the boxes. However I still do ask the tellers for halves and receive silver. I even had a teller deliver a whole roll of silver halves and 7 out of 8 loose halves to me at McDonald's one morning while I was eating breakfast. They were all 40's and I think she thinks the silver stopped with 1964.
