Just keep asking different banks if they will sell you the bags, I have asked about 30 banks and have gotten 8 of them to sell me all there bags, thats the only way to get a decent amount of stuff to go through.
over million , really mostly nickels and dimes .. that's over $280 a day , everyday a bank is open .. over 4,000 coins a day
I normally do a bag a day, and if they are 10,000 coins in a bag or dimes it doesnt take long to go through a lot of coins, I go through about 6 bags or stuff a week. Normally 1-2 bags or dimes a week and 4-5 bags of nickels a week and a half from time to time.
I've always lived on the East coast, and in my early teens, the fam took a vacation to California. I of course knew it would happen, but still it was so cool getting all the S mint coins in circulation, as it was rare to get an S mint coin in circulation where I lived.
I am in the San Francisco Bay Area. 90% of the pennies I get from the banks are from Denver. I try and avoid new coins. I usually get a box or two a week. The best ones are the mixed paper wrapped rolls from the mint. The plastic wrapped ones are usually dirty and corroding. I have no idea why. It definitely affects the chances of finding error coins. The Denver mint overall has far fewer doubled die errors than Philly or San Francisco.
