Now I know there is not a 1982 D steel penny, but this one has got me. It looks just like a steel penny only a bit darker and almost blueish but still shiny. It has the weight of a copper penny (3.14 grams to be exact), but no red or brown copper color. Any explanations? Thanks for looking.  |

Welcome! the copper plating has been removed revealing the zinc core. Probably a science experiment.
If its not magnetic its not steel.

Actually the coin is overweight by 0.03 grams. I would say it has been electroplated in something.

Probably right^ missed that. Still probably a science experiment.

A zinc cent would be lighter this sounds like a copper coin with .003 grams added plating.

The coin might have been heated. The weight could be off if the scale is not accurate or wasn't really zeroed.

Or the coin could have been dipped in mercury, which would make it a bit dangerous.

Isint mercury liquid at room temp? Yes and being a liquid it tends to "dissolve" other metals and form an amalgam with them. And no it actually isn't that toxic in its liquid form unless you decide to drink it. Mercury is actually nowhere near as deadly as its reputation makes it out to be. It is MUCH more dangerous if it is heated and the Mercury is vaporized. Inhaled mercury vapors ARE very dangerous. A mercury coated coin is actually very safe unless you: leave it on a hot burner on the stove, chew on it, or swallow it. There are some organomercuric compounds that are EXTREMELY poisonous, but in general mercury does not readily combine with organic compounds. Edited by Conder101
