Nickel Token

Where/How can I get a lot of quarters/dimes/nickels in the Los Angeles // Pasadena Area?
I’m want to try to find 1976 and pre 1965 quarters and want to sort through a lot of them. Whats the best way to find a bunch of quarters? I thought of arcades but the one by my house dispenses tokens. Anyone know of any good spots that i can just put bills into and get lots of quarters/dimes/nickels???
Thanks
Supermarkets and banks will sell you a roll or two, try your own bank first and have some sort of proof you have an account there in case they ask. . If you can get the operator’s number, a coin laundry should be able to sell you quarters. Same thing with a vending machine operator (candy, soda, etc) z
