You can't compare a 1979 with a 1990... 1990 is a Copper Plated Zinc Cent

The 1979 does look weird.. probably plated at one point then it wore away

 

I just picked another. 1979 copper looks the same. Coin not worn.

 

So, where's the 78 D from the title?

 

1979D not 78, my keying error.

 

OK

 

What does it weigh? Looks plated to me.

 

The coin has been altered.

 

Here’s my Son’s 8th Grade science experiment. Look familiar?

 

Yes

 

Cool

 

Here are some my students made

 

My Son was very proud when he gave me that cent set. It’s one of my favorite sets. (The set is the 61 and the 69). Some coins can be both worthless and priceless at the same time!
Reed.
P.s. thanks for being the guy that’s helps kids do this kind of stuff in school.

 

ALL 1979 cents are made of brass. 95% copper, 5% zinc That is a brass alloy.

 

Lol. It's about time someone pointed that out.
