I took $200 worth of coin roll rejects to one of my banks and deposited them in their coin machine. As the receipt was coming out of its slot I reached in to grab the 7-8 coins that had fallen into the rejects tray. When I grabbed them I had a strong flash of pain. I said something unrepeatable and threw the coins on the floor. It felt like I had grabbed broken glass, sharp metal, jellyfish / Portuguese Man O’ War sting or a nasty electrical shock. VERY painful. I looked around on the floor and in the rejects tray trying to figure out what had attacked me. But there was nothing there. I knelt down and picked up one of my thrown half dollars and promptly dropped it again. THE COIN WAS HOT! Hot enough to have just come out of a fire. I carry my coins in a plastic ammunition box and I held it up to the rejects tray and quickly scraped the remaining coins into the box. Then I went back to the coins on the floor. I scooped up one of the half dollars and was doing a “Hot potato” routine of bouncing it up and down in my hand until it cooled. A teller looked out of her window about 15 feet away and asked if anything was wrong. I handed her the Kennedy and said “Hold this” and dropped it in her hand. She promptly dropped it and said “That thing is HOT!” Now the branch management was called. They found me soaking my aching hand in the water fountain where the water was cold. The manager, a woman, wanted me to do an accident report and I agreed. But she was trying to orchestrate this and wanted me to go with her supervisor, a man, to a private office but I wasn’t budging until they opened the machine up. She was refusing but I insisted. I told her something was malfunctioning and maybe half of my coins were in that machine, uncounted. Plus I was afraid it might be on fire. That heat didn’t just materialize. She literally was blocking me from the machine with her body but I wasnt giving in. Finally she starts to open the machine but tells me there are coins in there but she can’t concede they may be mine. When the lid lifted there was indeed a handful of coins strewn all through the machine. In fact there were TWO reject trays inside, both with coins. They had probably been there a while because of the dust but who knows. as she started to close the lid I asked why all of those coins didn’t go into the outside reject tray so the customers could retrieve them. She faltered and finally said, “ Because. They just don’t...” WHAT?????? Those coins still have value and they are stealing it from the rightful owners. To be continued. This happened about 10 hours ago and the pain has subsided to the level of a wasp sting. There is a long narrow blister beneath my middle finger. HAS ANYBODY EVER EXPERIENCED THIS OR KNOW ANYBODY WHO HAS HAD THE SAME THING HAPPEN? I’d like to know about it.
