The first thing I can add is "Satain"? Also, the timeline of West Point minted cents, clarification of years 1982 and 2009 (both copper and zincolns were minted). 1943: zinc-plated steel 2018: conjecture (shouldn't be on the list even though they said it's a one year thing) I'm sure there's a lot more but thanks for the list! Edit: Just noticed you're about 45 minutes from me. Always nice to see a fellow Texan!  In Memory of Crazyb0 12-26-1951 to 7-27-2020

I believe you mean satin finish Lincoln cents (not satain). I know there is some debate about this, but the 1944 and 1945 cents used recycled spent war shell casings (and at least part of 1946). The alloy composition was similar to the original, but had slightly less tin. Quote from Wikipedia: Quote:
From 1944 through 1946, salvaged ammunition shells made their way into the minting process, and it was not uncommon to see coins featuring streaks of brass or having a considerably darker finish than other issues. Edited by batboy

I've been wanting some clarification on this, but from what I understand: if the two most prominent elements are copper and zinc, then it's brass. If they are copper and tin, then it's bronze.

The shell cases were 70/30 copper and zinc, the mint added more copper to bring them up to 95% copper 5% zinc. |

Good point. Like I said, there is a bit of debate over the war cents composition. It seems pretty clear that spent shell casings were used to alleviate metal shortages. I think the real debate is how much was used. Just look at a few circulated 1944 and 1945 cents. They wear slightly different and the color is slightly different. Most of the time I can pick them out of pocket change without even looking at the date.
But, we might be getting a bit off topic.

Sorry I know this is probably off topic but why are they mint marking the 2017 Philadelphia cent now ? If I'm reading correctly and going to remove it next year I had not heard of this .

I'm surprised no one has mentioned 1974 yet. Aluminum cents. Look it up -- interesting backstory to the only one authenticated by PCGS.
