Looks interesting can you take a pic of it out of the 2x2 and possibly a pic of just the mint mark?

it is only on top of the empty flip not inside it the glare is from the proof finish and the light.  |

Looks like some machine damage on this one? Here is what the mint mark should look like this year:  The mint mark looks disturbed. There was no listing on Variety Vista for a RPM. The 198 on the date looks like the same machine damage in the same direction. |

Still one crazy looking coin still a keeper in my book you can even the extra s with no loop and is far more extreme then a typical FFD. After doing more research suggests it is proof Flat Field Doubling - Please correct me if this is wrong any comments and corrections are always welcome. http://error-ref.com/flat-field-doubling.htmlFlat-Field Doubling (Imperfectly Aligned Proof Strikes And finding a example of the same year and mint mark double strike FFD Is it possible to be struck 4 times a a proof is already double struck and this example is doubled the normal FFD effect Quadruple Strike - Flat Field Doubling now that would be cool!! I found a less extreme example of the 1984-s triple s on ken potters site http://koinpro.tripod.com/Articles/...Doubling.htmHe calls it a Double Strike - Flat Field Doubling" on the Mint mark of a 1984-S proof cent (the doubling shows on both strikes resulting in a tripled Mint mark). Double Strike - Flat Field Doubling I guess that would explain the rounded shape.  http://error-ref.com/flat-field-doubling.htmlFlat-Field Doubling (Imperfectly Aligned Proof Strikes) According error-ref Flat field doubling adds a slight premium to the value of a proof. However, when the flattened design elements are totally separated from their normal raised counterparts, the value increases greatly. This new question I did some more research to if its worthless, small premium or has increased value. Because its a misaligned proof strike does it have a premium like research on error-ref states or is it worthless doubling? Edited by OcalaFlorida

My first thought was Zinc Rot but those close ups look really convincing to me. I am not an M/M expert and do not collect them but I would have to say you have something there.

Is it just me or is there some strange toneing going on around the MM and then about the same area on the REV?  It IS a Very nice coin!  |

Keep in mind that the proof cents are struck more than once. So it could suffer from machine damage twice and alter the devices. Flat field doubling usually makes a false device that is shallow. (Which is another form of machine damage on a coin.)  |

Coop, that was what I was thinking. But was it once for each proof strike or did if get feed again for another 2 strikes. Do you think it happened twice cause in ken's example I see only half of what is on the coin. So basically it is a coin that possibly suffered from misaligned shifting damage twice or shifted twice on once once each of two strikes or once on each set of double strikes?

Depending on denominations. Twice for Cents. More for larger coins. (How many I don't know) This was to make the devices raise higher and more relief on the proof coins.
