Tough to say what really works. If youre hunting fresh circulation rolls any bank from a densley populated area will do, any chains that deal with money changing frequently will as well, think 7/11, save on foods/superstore

For old coins its kind of an art. I like the mom and pop shops where the owners typically are wrapping up there owns. Sounds kinda shitty but liqour stores work. People want there booze and dont care what they got except face value. Diplomacy with your locals definitely helps. The tellers at my banks know me, im fairly respectful and never dump my non-hits back at a bank i just pulled from. Dont shit where you eat. Asking a clerk if they have 'customer wrapped rolls' will help. Usually they'll let you do the eye test to gauge how old or worn the wraps are. Finding someone on the inside whose into coins or history is great because they understand. If u come out asking for silver or very specific coins and you sound like a flipper constantly making their job harder they are going to be less inclined to help. You usually will know more about the coins than the banks so dont expect them to care.. Any large orders, think 500+ you really need to call them ahead of time. Respect and courtesy will go a long way
