[QUOTE="mynamespat, post: 2899618, member: 83738"]I dunno... All we can really do is guess (which I find to be a fun mind bender). Given that this is a recurring thread topic over time, I'm about 98.75% sure OPs coin did not leave the mint like that. At some point we'll discover this is the result of lesser known physical science experiment or something. If a person worked at a facility with a large vat of zinc at melting point, it would be super easy to dip the cent in the zinc vat. Once the zinc core melted, the the external copper would crush like a soda can for a moment before re solidifying. I just put a glob of solder on a zinc cent with a propane torch to see what would happen. It just rolled off. Then the zinc core collapsed... I didn't really put much effort into this experiment. Maybe with a bit better temperature control... nah, don't care..)[/QUOTE]
