Damn that is a good hustle if you got the time or just want to do it as a hobby. Its here and there honestly also coin stars spit out old silver coins alot. Its just something to look for when buying stuff with monopoly money or just ask cashiers if they have any old looking coins Ive even just went into the bank and told the teller before. "Hey I'm a coin collector do you have any old coins pre 64. lol Sometimes they seriously will sit there and look for you. lol its awesome most people do not know about free silver in circulation. Silver certificate bills hold onto too they are worth more then face if in really good condition a coin shop will buy them off of you for a few hundred dollars or more.
edit: of course when you go into the bank ask to buy the coins off of them.
Yeah when i was doing 4 or 6 boxes a day i would drop the coins off at a DUmp bank downtown and i would bring the bank works coffee and donuts
lol damn ballin
