Retail establishment where I work uses a dispenser to supply change to the cash registers and self-checkout stations; I was there when they were filling it with more quarters, and one was rejected... it was a 1952-S silver quarter. They let me buy it from them for face value (good deal as with current silver prices, it has almost $15 worth of silver in it!).
I was working in a restaurant as a kid. Heard the cashier open a roll of silver quarters and dump it into the till. I claimed all the silver before she could cash the patron out. Knowing I’d have to replace that roll with another, I quickly claimed the silver quarters in the lockbox. Good thing I did. There were three more rolls and a roll of uncirculated 1965. I gave her that roll. In short - 4-rolls of silver for face value. That was a good day!!
