1984-S Lincoln Cent Proof w/ Double Strike - Flat Field Doubling on MM

I found this little 1984-S proof Lincoln Cent a few months ago. I find it pretty interesting. There is probably not much if any premium on something like this.

This a Odd little coin it is NOT A RPM, 1984-S Lincoln Cent Proof with Double Strike Flat Field Doubling on Mint mark. It is also NOT A VARIETY but a IS A Strike Error.

ken potter has a less extreme example on his site. BTW same year and mint mark

I collect these but they might be so called non collectable

I believe it might be possible that this coin possibly suffered from misaligned shifting damage twice or shifted twice on each of two strikes.

Is it possible to be struck 4 times a a proof is already double struck and this example is doubled the normal FFD effect.

Is that a

Quadruple Strike - Flat Field Doubling now that would be cool!!

Are you sure this is not an RPM...I'm not? Have you ever sent it to Wiles?

It would be nice to see a focused close up of the mint mark.

Ditto.
On all points.

 

If you guys check out Ken potters example of same year coin and mint mark is only double struck.

There are multiple of these floating around I think they are cool but they are strike errors not anything on the die.

I did not check with Wiles...

I went by my own research looking at ken potters example and by talking to Richard Cooper aka Coop a trusted variety expert who posts on a lot of forums.

This was my primary reference on the subject, and although I can see some similarity, I can't quite reconcile your example with Diamond's explanation of flat field doubling.

"I believe it might be possible that this coin possibly suffered from misaligned shifting damage twice

Possibly the better explanation.
