1996 Lincoln Memorial Penny Is This Poor Die Alloy ?

Can't tell if the scratches are on the coin from cleaning or die scratches but am leaning towards die scratches, because you can see it evenly down in the bays. As for the tint, it looks to have come into contact with heat of some sort. Cool looking though.

I'm not sure what you are trying to ask, the words "poor Die alloy" don't even make sense.

Dies are what is used to strike the coin and are made of tool or die steel, a special alloy that can be softened for the manufacturing processes and hardened for the strikes (within die maker's definitions of hard and soft!)

If the alloy used was incorrect, but managed to make a die that didn't shatter on first use, you wouldn't be able to tell from the struck coins.

Mid-year 1982, the mint changed the composition of the cent from a 3.11 gram bronze, 95% copper 5% tin/zinc alloy (used going back to 1864), to a 2.5 gram copper plated zinc core.

You have always been able to make cents display weird colors via heat treatment, it's just different between the two compositions - heating up the plating without disturbing the lower melting point zinc is tricky. If you look adjacent to the rim under the L of LIBERTY you can see what looks like exposed zinc, i.e. the copper plating flaked off.

What you have, then is a ZLincoln (copper plated zinc Lincoln) which was exposed to heat. Could have been a torch, could have been the dashboard of a car in the summer sun. But whatever happened, it's damaged.

again pretty new to coins just trying to learn and understand the billion errors and Post damages that come to coins, for the title reason being is I was reading in Err-ref and thought it matched but apparently was totally incorrect and much apricated on the complete explanation. thanks so much
