Johnny Reed Collection Posted May 22, 2019 Share Posted May 22, 2019 1955d only 2.98 g I assume it’s very expensive brass error! What do you all think. Link to comment Share on other sites More sharing options...
Just Bob Posted May 22, 2019 Share Posted May 22, 2019 Average weight is 3.11 grams. Acceptable tolerance is .13 grams. 3.11 - .13 = 2.98. Your coin is just barely within tolerance for a Lincoln cent. So, it is normal, but only just - kind of like me. Link to comment Share on other sites More sharing options...

Greenstang Posted May 23, 2019 Share Posted May 23, 2019 How can you tell it's brass. Did you have it tested? The only difference between brass and copper is the amount of zinc in the alloy which cannot be determined without testing.

Lincoln Cents are not just Copper, they are Bronze which is an alloy of Copper and Tin, Brass is Copper and Zinc, I Think. Not counting Steel Cents and Shell Case Cents, of course.

Conder101 Posted May 23, 2019 Share Posted May 23, 2019 The french bronze that the Lincolns are made from is 95% copper, 5% tin and zinc. there is no mandated percentage for the tin so it can vary from 2.5% down to just a trace and still be the legal composition.

Member: Seasoned Veteran DWLange Posted May 24, 2019 Member: Seasoned Veteran Share Posted May 24, 2019 The tin content typically was just 1%, and this was eliminated altogether 1944-46 and then permanently 1962-date. Since that time "bronze" cents are more accurately described as "brass," but the old term lingers for the 1962-82 cents. Link to comment Share on other sites More sharing options...

Dwlang what’s your thoughts on this being it bounces between 2.8 grams and 2.9 grams Link to comment Share on other sites More sharing options...
Greenstang Posted May 24, 2019 Share Posted May 24, 2019 Quote it bounces between 2.8 grams and 2.9 grams If it bounces that much I would say you need a new scale. That's 1/10 gram Link to comment Share on other sites More sharing options...
