My advice is to call you local bank branches that you have a bank avccount with and ask to speak to the manager.
introduce yourself professionally, and get their name and use it a few times while talkign to them on the phone, it helps to show professionalism.
Then basically ask the manager if they could order a box of quarters for you and you would pick it up if they can and see what they say.
Now half dollars and dollars are a real problem, banks don't like them, they do not use them and they never want to see them ever again if they did get them for you.
If you ask for halfs or dollar coins, they will likely shut you down right there.
Best to start with commonly circulating coins and build a relationship and when speaking to the bank manager or head teller after a while and they know you, MAYBE they will order those types of coins for you, but maybe not. I'd get the door open for pennies, nickels, dimes and quarter and worry about the non-circulating coins later, which are much more difficult to get a bank to order for you..... because they hate dealing with them, and the people over their heads hate dealing with it also.
Contrary to popular belief, there isn't much silver in Halfs anymore out there to find, and there isn't much in quarters either. there's still some in dimes though.
there is this coin roll hunter on youtube that was getting halves from a few banks, well he went and had them order like 38 boxes and of course they did, but now for some reason (Guess why?) he can't even get a box of pennies anymore from any of them, and has $19,000 in halfs he needs to dump somewhere. LOL that coinstar fee is gonna be a killer or he's gonna have to try to spend them most likely, but they will be showing up at all the local banks if he does spend them... pretty much killed his own connections.
I ask at banks whenever I stop if anyone turned in any halfs or dollar coins they want to get rid of, and take what I can get rather than ask for them to order them for me in boxes. It's never caused a problem but I can't bring them back to the bank that orders for me.
That the other thing that's really important. Whatever bank does order coin for you, DO NOT dump back in that bank, they will cut you off, in fact, do not dump at a different branch of the same bank nearby, they will talk to each other if a bunch of half show up and they will get you cut off also. Do not ask to "swap" searched rolls for new rolls or "trade out", If they get it for you, say thank you and take it, and they never want to see it again. they will continue to get them for you if you do it this way, be nice, don't ever cause a problem, and if they miss orders her or there just act like it's not a problem, maybe next week. They are doing you a favor really, they aren't supposed to service roll hunters. Let them set the rules on what's comfortable for them, then as time passes see if you can up the orders each week.
If I get $20-$50 in halfs or dollar coins at a time from asking for customer turn ins, I don't mind the coinstar fee, or I take the Amazon
giftcard, but I make sure I don't dump where it will affect my "get" bank where my coins come from.
