Is there a set guide to when Bronze Lincoln cents were made? Basically, I would like to know if Bronze Lincolns in the 1970's and 1980 are considered errors? (I have quite a few Bronze (yellow) from the 60's - 70's & 1980 - before spending the $$ to put them on ebay, I would like to make sure they will sell). Thanks once again! |

bronze "brass" made from brass from the war these coins were minted from 1944-1958
but most of the coins that look yellowish or like bronze is nothing more than a polished coin .i have heard of a few that were made from bronze later but only in passing I have never seen one and I'm not sure that any have been verified. but if you have a cent that appears to be bronze or brass colored it is more than likely cleaned or polished.

The composition of Lincoln cents was .950 copper and 0.50 zinc and tin from 1909 to 1982 (including part of the 1982 mintage). The exception was 1943 when the cents were made of zinc coated steel. The composition of the Lincolns from 1982 to present is 99.2% zinc and 0.8% copper, plated with pure copper.

Well said. I still don't know how to tell the difference between copper plated zinc, or bronze. Not that I'm checking every 1982 cent I come in contact with.

For the copper 1982 (and pre) pennies, weight is 3.1 grams - After 1982 they weigh 2.5 - If you find a penny that weighs 3.1 grams after 1982 - you have a VERY nice small fortune!
There is a standard for slight weight differences that I have found in the Givt. procedures.
I could dig them out if anyone wants them.

i know what you're talking about. they aren't worth anything. place a copper penny (before 1982) in a solution of sodium hydroxide and granulated zinc. when it turns silvery in color, take it out and put it over a flame. the zinc coating melts and mixes with the copper creating a brass colored penny.

Although I can appreciate the Idea of altering a coin by way of chemical reaction , and or plating , I do not however see the similarities between the two different cents the 1943 cents are Zinc plated steel. The 1943 Steel cent is a piece of history ,,and although in circulated condition carry very little value above that of an ordinary Wheat cent ,, In higher grades they carry a significant value .
