That is not a D over S mint mark.
That is a Split Plating issue. 1992 Cents are copper plated zinc. They tend to split around that particular area.

Read the first part of this webpage on Zinc Rot -

I need a sharper closeup to decide.

 

If I remember correctly 1992 is the year the mint started using the CNC machine to produce dies, and no longer stamped/punched mintmarks by hand.

 

It is not a D over S Mint Mark..
It is not a D over anything Mint Mark

 

no, no, no

 

Whatever the problem is at the mintmark, gas bubble, split plating, pmd, whatever, there is no D over S mintmark cent

 

Yeah but

 

If anything. It is an interesting coin. But just a plain ole d mint mark

 

Check for closed AM just for the hellavit

 

This is a 1968.

 

Thats a winner winner chicken dinner

 

Well, I would keep the coin and get a second opinion.

 

That's machine doubling and very common. You are looking for Die doubling not a doubling that happens during the striking process.

There is a wealth of information on that website, Make it a favorite and use it for your research.

 

It's impossible to happen, no need to keep a damaged cent.

 

So that 1968 is definitely machine doubling? And thanks for that link, its definitely helpful even tho the machine doubling and die doubling looks very close alike.. thanks again!

 

Old Hoopster is really good at explaining this. But see how the doubling has taken away from the design. And not added to it. That and the flat and shelf like appearance is a sure give away.

 

Not an over anything mintmark.
