2 problems with that, 1. the coin would be smaller because a cent is larger than a dime, and 2. it wouldn't be struck nearly as nice as that coin was.

I'm still betting on a chemical reaction / environmental damage.

3/4 inch or 12cm I dont have a mm ruler. it is the exact size of a normal penny. if it were a chemical reaction, then why would it be lighter than a normal one? some size but a tiny tiny bit thicker than a normal penny.

If the chemical reaction consumed the copper in the alloy on the surface of the coin, proportionally more tin/zinc will be left, giving the coin a more silvery/gray appearance. I thought it possible, given the appearance of the grain on the obverse. "Pickling" was also done long ago to give low silver content coins (billon) a more silvery surface, by chemically removing the copper. |

Tin and zinc are active metals, whereas copper is not. I doubt a chemical reaction would preferentially react with the copper. I would be inclined to go with the alloy mixture being different to begin with (more tin and zinc). |

unless it sat next to aluminum for any period of time alum and copper make aluminum oxide which would transfer aluminum onto the copper but it would take like 50 years

If the OP's stated weight is correct then I doubt any type
of chemical reaction, so to speak could cause that much of a weight reduction. It's either just a cast trinket or a different planchet. Probably not, but have to ask anyway.
Any reeding at all present on the edge ?

 to the forum. Since you are new here I must say I am no expert collector nor am I even a novice in error coins, so I am learning mainly from posts that have been posted here. The surfaces look kind of grainy like it has been chemical treated like some of the others that have been treated with acid and other things shown on this site before. I am not saying that is what this is I am just saying the surfaces kind of remind me of those coins that have been posted that had been treated with the acid and other chemicals. |

Im sorry but I think its counterfiet. The wreath looks the same as some of the fakes I buy in China, to fill the spots I will most likely never be able to buy. You can compare it yourself look on the net. The casting and strike of the wreaths are simular to yours, and both differ from the original coins. Just my opinion I could be wrong of course.
