1983 D copper cent?

Since the scale appears to be accurate it is either copper (unlikely due to the silver color on the reverse) or a copper plated zinc struck on an over weight planchet. The next step (without spending a bunch of money sending it in) would be a specific gravity test. That would tell you for sure. A copper cent would have a SG of 8.83 and a plated zinc of 7.17

What is a gravity test and how would I do that? Also, would I be able to send it to CONECA and let them do a test?

 

As others have indicated, this cent was struck on a planchet punched out of zinc stock that was rolled too thick. It doesn't appear that the plating was excessively thick (the other possible cause of an overweight zinc cent).

 

I do believe it is zinc because it sounds different than a copper coin when dropped on a wooden table.

 

This may explain the odd weight then.

 

Now, how can I explain my extra weight?

 

TV cooking shows. Damn you Rachel Ray, Guy Fiery and BBQ pitmasters!

 

What sound do you make when dropped from a height?

 

Depends if anyone's around to hear it

 

I had it looked at at a coin store and he couldn't explain it either. His only guess was that maybe it had a foreign material in it. He suggested I send it to CONECA.

 

Lol, me too!

 

Plop, Plop, Fizzle

 

Depends on the height and whether you mean the sound he makes on the way down or the one when he hits.
