It doesn't look like it was plated to me, but there are those dull metals like iridium. there's a chance its an unplated zinc penny.

Not if it sticks to a magnet. It maybe be plated. I notice the tops of the devices are glaring from the light source. On the missing plating examples, they don't have a glare from light.  Edited by coop

Almost certainly plated. God that 2006 visage of Lincoln is ugly.

Coop - in your example it says "No accumation bumps". I have no idea what they are talking about? I think that "accumation" is not even a word. Do they mean "accumulation"? If so, I still don't know what an "accumulation bump" would be?

This is kind of a tough one. I think a person would have to have this coin in hand to tell for sure what it is. Looks unplated to me.

LOL. Spell check doesn't work on Photoshop. 'accumulation of' was the correct words. Brain must have been a quart low that day. LOL
Fixed it.

I think it's been plated and that's what the magnet is attracted to.

I missed the part about it being magnetic. It cannot be an unplated cent if it sticks to a magnet.  |

What should an unplated CENT weigh?

The plating weighs .05 grams or a little less, and the Weight Tolerance on the cent is +/- .1 grams. So the tolerance range is four times the weight of the plating. |

Aside from iron and most steels, the next most magnetic metal is nickel but I doubt that a plating would be enough to allow it to stick to a magnet. It looks to be in great shape with maybe a little softness of strike on the reverse top. There is a very remote possibility that it is a test metal strike that escaped the mint but I would exhaust all other possible explanations first.

There is a weak strike in "states of"...I can pick it up with a refrig magnet but if I just tap the magnet it will fall off...I have a few other obviously plated cents that have no magnetic effect at all.

My reason for thinking this is that the Mint Commissioned an Alternative Metals Study. This was authorized by Public Law 111-302 (the Coin Modernization, Oversight, and Continuity Act of 2010), in which the Secretary of the Treasury was given "authority to conduct research and development on all circulating coins." The final report on this study was submitted to the mint in August 2012. For an experimental metal planchet to be struck in 1999 would be just a bit premature. |

Therefore, I am not convinced the weak strike in this area is material to trying to determine anything about what has happened with the coin. |
