Thanks as usual @John1 for being right at the top!! Well after going to Variety Vista and doing my comparisons it looks like the "North" one.. but I do not know what term to call this RPM as it looks closest to (see link) http://www.varietyvista.com/02b%20L...1SRPM010.htmIs RPM and S over S the same thing? And lastly I still am getting a better understanding of dd vs md ..but I don't have a good enough visual of the rest of the features. Thanks for your assistance. Edited by cocoanutz

With the pictures it looks like a normal coin. Can you get clear close ups?

Thanks for looking into @DavesErrors . These are the best I can come up with ..and should show the splitting.   |

Hey guys, does this like like an impaired proof? @ cocoanutz the link you supplied us to compare your cent to is for a Proof Cent and I'm leaning towards your coin to be a business strike (let's see what others say) also may be a broken punch..  |

Thank you @GreasyFingers.
I got my 60x mag and I wish I can show you what I see (looks positive) but need your eyes of course. Now, for learning purposes, this may have been meant as a business strike coin vs a proof (mismark)?
Thanks for sharing.

cocoanutz, Your coin is not a proof. I am not seeing a doubled die or a RPM. Research some more and post a attribution number and the site you found it on so we can do a comparison.If you are using a 60x jewelers loupe,that is too much.You should not go higher than 14x with a loupe,the image gets distorted.

I can see a TINY LITTLE SPLIT in the top of the S But hard to tell if its not just Damage. ( IF ) it is a RPM It's a very MINOR one at best.

Thanks again Gents. @John1 I appreciate the magnification suggestions  Also here is that link I was comparing this coin to with similarities http://www.varietyvista.com/02b%20L...1SRPM010.htmWhat is this coin type considered with an S mint mark if it was not struck as a proof coin? And thanks @DavesErrors there is also a split or some separation (see bottom fatter tail of the S looks like a dimple).  Edited by cocoanutz

@John1 Holy smokes I thought all S minted coins are considered "proof" where one might open it and it can get lost in regular circulation (but still called a proof or WAS a proof). Geez for us beginners, this is a lot to grasp. There are also then business struck S coins just like D, P, and W?

 Not all San Francisco minted coins are proof. The mintage numbers on the 1971-S Cent are 528,354,192 business strikes and 3,220,733 proof strikes. Proof coins are struck with special polished dies on special polished planchets so you would get mirrored finished fields in 1971. ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!!

Thank you both.
How long does that mirror finish hold up on a coin (that, let's say has been out in circulation since 1971)? So now it is differentiating with this coin either being an impaired proof or a business strike S penny. @John1 just by looking with his trained eyes..he knew business strike. How would the beginner know?

Proof coins are struck twice by the die, making the rims more squared (business coins struck once) Proof will have frosted devices and mirrored fields..Do an ebay search for "1971S proof Lincoln Cent" and the 4th one down (selling at $1.50) will show you a nice example. Even an impaired proof will still show as frosted and mirrored |
