Need help with 1956 D penny

[Cclantz]

If you look at the prices you can see the D mint Mark looks to be stamped in to the 9
I’ve looked all over trying to find one like it can anyone give me info on it
Is it a error ??
Is it nothing special?? Just wondering thanks much

I think this coin has had some rough times in the past which has smashed the obverse raised area and also tore them up some. I dont think its a mint error - in my view.

Thank you if you compared to the other 1956D in the picture the mint mark is in a totally different place

Nothing special. They used to add the mint marks to the dies by hand. They can be anywhere as long as they are under the date.
