1992d puzzle

[Guest]

im a new hobbyist and still learning but i have a 1992d penny which is hard to classify if its an error or variety. maybe someone can spare me some of their time.

1 dot at the back of the head and forehead which is the same as the dot in E PLURIBUS
2 doubling in year and letters in reverse, obverse
3 repunched mint mark
4 extra dot above pl in PLURIBUS
5 check the sides of the memorial
6 check the pillars
7 the line in I of liberty to I IN GOD
8 the grey shades beside the letters and numbers both reverse and obverse (solved) split plate doubling from LCF
9 extra dots and lines all over
just to name a few

Sorry, I see nothing but plating blisters and corrosion. The date shows no doubling either.

that was quick. thanks anyway. still keeping my hopes up.

The mint mark is corrosion. In 92 the mint mark was part of the master hub. Not punch into it. Like was said, those dots you're seeing are plating blisters.

Welcome to the forum.
Zinc Rot: Zinc corrodes easily when exposed to the environment. When the plating is split on a copper-plated zinc cent, the zinc will often corrode under the plating, and push up on it creating a bigger and bigger fissure. Due to the strength of many of the hand-punched mint marks on pre-1990 business strike cent dies, this is a very common place on Lincoln cents for the plating to split and for this corrosion to take place.

The mint ceased hand punching the Lincoln penny MMs in 1988 or 1989 (Can't remember which)... Everything else I see is like the others stated... Also The Lincoln penny was a solid coin until mid 1982 when the mint went to a copper plated zinc core... Here is a link to check out about large and small date Lincolns http://www.lincolncentresource.com/s...malldates.html Hope that helps a little???

While this looks like it could be a case of incomplete plating, the plating has actually been chemically stripped in the center. I've seen many cents with this same pattern. I used to be fooled by the exposure of zinc on the lateral side of letters and numbers, because it looks like split plating. But in this case it's because the plating is thinner here as the result tensile stresses set up by the strike. As a result, the corrosive solution preferentially strips the plating away in these areas.
