And I have a gut feeling it's copper or brass whatever 1982 and before planchet SG test is closest to it

Ok so I got a metal calculator did brass with diameter and what's left to complete the thickness of a penny and it is .868 grams which would put the planchet at 2.97 grams but I'll only know for sure when I get it analyze because if I did it with zinc it is 2.7 grams there about.... I'm finding all diffrent ways to prove my thoughts wrong lol

If a coin is two different metals, not alloyed together, but one plated onto the other, a SG gravity test can't tell you which metal it is. The test won't prove it is either of them, only a combination of the two.

No, it is Copper plated Zinc. Brass is an alloy, not plated.

Yes from 1963 to mid 1982 they were copper alloyed with zinc making them brass.

Admittedly, I have not read the entire thread. But this would almost certainly be a cent struck on a zinc planchet (later plated with copper) punched out of rolled-thin stock. I have a half dozen or more underweight zinc cents, several weighing considerably less than 2 grams.

 That would be the only answer that would fit the results of the testing that has been done thus far. |
