Change machines in laundromats is a good way to get a lot of quarters, outside of a bank. Also might try video arcades (if you can find one, and they use quarters instead of tokens) and casinos (if you can find one that uses coins instead of tokens or cards for their slot machines). Some grocery stores might, if they're in the mood and you ask nice, give you a roll or two of some coins. Results may vary, but can't hurt to ask. Also would suggest check cashing places or payday loan places (often the same place lol). But banks always seem to be the easiest and most reliable way to get significant quantities of coins to look through. P.S. Not sure if this is still true or not but back in my early coin roll hunting days would often get rolls of coins from gas stations to look through. P.S. The example of a clad Kennedy half dollar in my Dansco 7070 is a 1971-S slightly circulated proof that I got from a casino in Biloxi, MS. They still had 50 cent slot machines that actually used half dollars; you could put money into them and immediately cash out to get half dollars to look through. Most were pretty beat up though, but hey found a nice one that I still held onto!
