1982 Lincoln Penny New Variety?

Hi All,
There is definitely some doubling on Lincoln's Profile, but I'm still having trouble with distinguishing which kind. I was hoping to get some opinions before I got too excited.
Thanks for looking!

MD - Mechanical Doubling

 

Dang that's what I was afraid of.... still worth anything?

Large date Zink. Machine doubling.

 

It is a small date.
The small date Philly zinc has a premium.

 

Isnt that technically Die Deterioration Doubling?

 

Quick question (pardon my ignorance) but is it possible/likely to find the same mechanical doubling error on a different coin?

 

Yes, many , many, many are produced before the mechanical problem becomes noticeable to the press operator or the inspection team. As their job really is to produce large number of cents each shift and if 95% are near perfect and 5% are a little 'not perfect' the only people who notice are people like here.

 

Thanks! Still learning.

 

Yes, but not like you would find a variety. The two coins more likely than not originated from different dies.

 

Yeah it kind of depends on the setup and specifications of each individual die press.

 

Sorry one more question... (let me know if this should be a new thread) without the benefit of a precision scale or knowing the date would you say this penny is copper or zinc and also would this be die deterioration doubling?

 

So here is a pic of the front....

 

1982 was transition year from copper to plated zinc so 69 would be copper. No expertise on die deterioration but looks like it could be. The elements and fields both have a stippled effect and that could be from overused die. Or defective planchet plating maybe. Looks like evidence of strike error as well.

I guess this should have been a different thread.

 

Thanks for the input!. I knew about the 1982 transition that's why I was confused, didn't know if they had any experimental alloys in 1969. I did some research after posting and the only thing I found similar were post 1982 cents and a few with heat damage but it is in such good condition otherwise don't know what would have caused it...

 

The ping test.
Drop the coin onto a wooden table or a hard surface.
Zinc will sound light but dull.
Copper will be a very bright high pitched noise.

the 69 has had a bit of acid on it.

 

Is that a scratch in the obverse of the coin near the date or is it a die crack?

 

Its bubbled up not indented so maybe die crack or from from whatever caused the stippling...
