I think boxes of rolls are the way to go if possible. Just talk to the teller. Halves especially. Nickels you should be able to score at least one box without a special order. I agree with ratman, halves are fun for silver but I don't seem to find very many keepers. Nickels you get more keepers I also keep pre 60's plus if you fill an album there are a lot more holes to fill, plus you can constantly upgrade.
V nickels, buffalo's,
War Nickels and cant forget the older gems. I think it's fun plus you get the coins for face value. Good luck.
