I’m confused, sorry. Is a 1983 Penny supposed to be zinc and weigh 2.5g? Or is it rare this way? And why were they made this way during this year? I don’t know anything about coins so I’m curious. I found this penny in a bag of coins in my shed. Some are cool looking and from other countries but this one really caught my eye. Please, can you explain to me a little more clearly? Thank you!

Cents were transitioned in mid 1982 from copper planchets to copper plated zinc Planchets. Copper weigh 3.11 grams and copper plated zinc 2.5 grams.. so yes, a 1983 is 2.5 grams.

But all coins could have a plus or negative in weight. Many are within tolerance.

 

Government waste in play here.

 

I have a 1982d &1983 d
One weigh 3.09g I used a .0.1g x 100 scale
Other weigh 2.54g

 

I have a 1983 & 1982 I used a scale 0.1gx 100
One weigh 3.09
Other weigh 2.54g

 

Perfectly normal if the 1982 is 3.09 and the 1983 is 2.54.

 

Both are within weight tolerance. They could be plus or minus just a bit.

Interesting. I didn't realize that there was a bit of a weight difference for the 1943 Steel Planchet Cent late in the year.

 

I seem to remember they changed planchet supplier later in the year?
