Beginners: Roll Hunting Etiquette Guide

Hi, I am very new at coin hunting and I greatly appreciate all of the comments and information that has been shared here. I just visited my first bank Wednesday for rolled coins. I asked for 10 rolls of pennies and 3 rolls of nickels thinking that wasn't too many. The teller appeared to want to know so I offered the info that I was coin hunting, he smiled and was very helpful. Anyhow, my first roll hunt brought me 3 buffalos and 2 Queen Elizabeth one cents. Neither are old or of much value but it was exciting to find those in rolls. Again, thanks for the advice!!

There aren't enough words to describe how important it is to be nice to the tellers. My current bank hires 24 year olds and they always love to see a teenager walk in that doesn't want to withdraw all of his money.

When I'm going through penny rolls (being nice to a head teller brings dividends!), I take what I want and dump the rest at a different branch with a coin counter. Realistically, I shouldn't see these pennies again since Canada discontinued them, and each new bunch I get from the teller should be new rolls brought in from customers.
But if I'm doing nickels, dimes and quarters, I'm usually pulling only a few out of each roll, so I top the rolls back to full with others I don't want from a supply, mark the rolls so I know which ones I've gone through, and then just take them back to the original branch (who knows what I'm doing), and exchange them for more unsearched rolls. This way I am not depleting their stock of coins for other customers (except in the original purchase), and they are then happy to give more unsearched ones. When the head teller eventually says that all she has left is my marked ones, I go to another bank for a few weeks until all my old rolls at the first bank have been passed out, and the teller has ordered in more, or collected enough loose change from others and made her own.
I have about four "exchange" banks nearby, so I could even make a couple trades per day, once per bank of course.. It took about 5 months, but I turned 40 rolls of Canadian dimes into 40 rolls of American this way..

One 1967 out of $500 worth of halves might be better than average for most. I roll hunted steadily since 2008, and finds for the last three years had been dismal, (halves). My dime finds never dropped below 1 silver per $150. Hit up 20-30 boxes of halves for a better account of averages.
