I found 3 1996 JFKs in a roll of them (from the bank) that likely was a bank roll. Three of them were sequentially in the roll together and have similar, but different shaped "splotches" in front of JFKs effigy. Under a stereoscope it can be seen these are not not glue or something else on the surface. The coin's luster is bright, even on this splotch. Its just the luster on the splotch shows up brighter at a different angle than the rest of the surface of the coin. So what is this? I also see I need to get some sort of air system to blow dust off of coins before I take pics!  Yes - sneezing... I know  |

Did JFK catch cold when this coin was struck?
Surface stain has discoloured the metallic surface. Most probably won't be removed with acetone.

Thanks for the opinion sel, but I do not believe it is a stain. Especially since three successive ones in the roll had it in the same place and some of the successive ones after them had smaller spots in the same area. It seemed like whatever made the spot dissipated as more coins were made with the die.
These were in one roll of many that were in a box I got for roll searching. Over half of the rolls in the box were brand new 1996P. I suspect they had been siting in storage for some time.
Again, the pic makes it look like just a stain - but it has luster to it - just at a slightly different angle than the surrounding field.

I admit knowing Struck Through Grease causes lettering/etc. to not show up. Is this what it looks like in an open field? I guess maybe that's what I should have asked in the title... "is this a Struck Through Grease error?" |

It was struck through a thin layer of oil/grease. Thicker and more viscous accumulations will result in obscured detail but a thin layer will just disrupt the luster in an open field.

it's just a sharpie marker spot that was done by a coin roll hunter.

Earle42: I know my argument has been weakened somewhat by the point you make.
I must believe what you are suggesting may be right, and the stain is not post Mint.
I cannot dismiss in my own mind that what caused the stain may have diminished with subsequent strikings and the substance that caused it may have progressively diminished. There is a possibility that the suggested substance (by innuendo) may have been on the die.
Just a hypothesis. Perhaps worthy of further discussion.

If you don't think it is a stain, and you say that the flow lining = mint lustre? is not there, my next considered possibility is that this area has been struck through oil or grease.

There is luster - its just that this area has its luster reflect better at a different angle than the rest of the coin.
Conder - what kind of difference are you suggesting - I have no idea.
