Shocked At Kennedy Roll Hunt

Went thru my first two boxes, ever and found, two, 67s. No machines here that are free and no papers. I planned with the bank to take them in loose. Mgr goes in back with a teller to check my 2x500 count. Supposedly I shorted myself two coins. Chatting with nice teller. They were slow and wrapping up for 6;00. I ask about unusual stuff. Starts looking thru her small till and while watching her, young eyes ,scanning dates; I no sooner say to look at edge for a solid grey line and she says " here's one" during the dime compartment. Righttttt I say and think. Holy Rosey I look and its a 48. She takes my quarter and hands it over with a nickle. Said she was sick and I was happy with the dime loss, either way.
