1975 “S” Proof Lincoln cent Plating error??? 0

[LucaAlexBrassi]

I removed this from a mint proof set years ago and has been in safe storage since. Also in the set was a completely gold 1975 no s proof dime. This was before I knew any significant guidelines to numismatics. Back to this penny. Is it normal for the coloring to have gold, purple & silver tones. Very difficult to get clear picture that fully catches just how unusually vibrant the tones are. Is this what’s considered “Deep Cameo”?

Copper can turn many colours depending on the environment it was stored  in. It is not unusual for it to be toned multiple colours on the same coin.

It can and does happen, usually its a by product of improper storage.  Some people very much like toned coins and some do not, deep cameo refers to when a coin looks black and white.  The fields will look black and the portrait/letters look white (copper in the case of cents).  I don't have a photo of one of my DCAM Lincolns so I pulled this obv from the NGC explorer.

I hope those scratches are on the holder and not the coin.

Were going to have to see pictures to believe that. Considering currently there are only 2 known. And last I knew one of those was still in an unopened set.

I kick myself in the rear quite often.. I didn’t know anything about coins really and lost all but this Cent over the years.(From the proof set I ignorantly opened) The scratches are on the holder.

The coin was colored this way in the capsule from the mint btw.
