Many things can effect the color of the Copper Plating on the Copper Plated Zinc Cents produced from 1982 to Present. It is hard to say what specific chemicals or substances are responsible for the color. The coin is also showing bubbling of the Copper Plating. This is due to minute cracks or breaks in the Copper Plating and an unknown chemical/substance having contaminated the Zinc core, causing a chemical reaction and the bubbling in the plating. As far as the thickness and the double rim is concerned. The coin appears to have been struck slightly off-center which forced excess metal from the planchet to one side. I can't tell if the planchet is thicker than normal, so a precise weight of the coin is needed. The coin should weigh 2.5 grams and normally should not vary from that by more than +/- 0.1 gram. If the coin is say 2.8 grams or heavier, then it was struck on thicker than normal Planchet Stock. Since the coin was apparently struck off-center by such a small degree and even with a slight double rim, it has very little extra value above face value. However, if the weight of the coin is abnormally higher than the normal 2.5 grams, the coin needs to be examined to determine if it was struck on an Experimental Planchet or it was just struck on thicker than normal Planchet Stock. If the coin is heavier and thicker than normal, either of the afore mentioned reasons could boost the value of the coin well above it's face vale and especially so, if it was struck on an Experimental Planchet!

Chris,

2.1 grams seems a little light! Although it is impossible to determine the weight of a coin from pics, I see nothing in them that would say that the coin is that far underweight. Maybe the Coin Dealer's scale needs to be calibrated or replaced. I have read and even responded to some of your Threads and since you are into searching for Gold also, you might want to invest in a digital scale for weighing Gold specimens and other specimens, then you can weigh coins that are in question.

Here is a shot in the dark but. Is there a chance this is one of those screw together type spy coins? It would explain why it's lighter if the scale is true? Not sure if they even made the screw together coins as pennies. But thought it worth a mention
