Sorting last night I spotted a dark, mottled cent in the hopper. Not wanting it to jam the chute I pulled it out. It easily bent in half in my fingers. "What the he...?" It was cork! Exactly the same dimensions as a cent. Is this a first?
Sounds like a slug like kids put in gum ball machines to get the coin mech to turn and give up the gum. I have yet to find any but I keep getting a small 20 something peso looking coins. I weight is 3.5 grams so I bet the counter machine at the bank will kick it out but I still find them in rolls I buy from my source bank.
Search Youtube, one day I found a bunch of videos on how to trick machines with devices and in some cases using programing codes on coke machines to get them to put out change. One kid tore a chunk of cardboard into a circle and got a gum machine to work.
