@penny, first welcome to CCF. Second, that looks to me like there is a residue or solder on Abe's head. This sort of damage would have occurred after the coin left the mint.

 it looks like solder on the coin. Just damaged to me. no extra value. But a measurement of the weight of the coin will tell us if it is extra metal (like solder ) or not.

Some how in that period and before, the zinc from the alloy oxide. The color is almost same with the OP background of the photo. This oxide grow like a mushroom.

Like I say it is an oxide of the alloy. Is no add material on, look like but it is not. This oxide is some blue turquoise color.

Thanks Silviosi,for your information. I just search oxide copper penny and saw some examples. The color doesn't look like this penny. The color that on this coin is more silver looking or could it be a piece of zinc that was stuck to the planchet?

No, the zinc of the alloy was more condense in that part and there oxides. Seem to be the color like silver but is more blue and like a mushroom.
PS: This is like I mention: characteristic to zinc.

 to CCF. It looks like a "substance" on the coin,so PMD. Might be solder might be some type of glue.Weight is normal,but there is also a mint tolerance of +/- .13 grams to factor in. John1

@sil, I'm going to respectfully disagree with your conclusion that this is zinc oxide. The coin was minted in 1970 and so is nominally 5% zinc, right?

Yes Spence was in 70's. You say only 5% zinc, correct. This coin is a part of the roll with the alloy un-mixt properly. If you look very precisely, you will see the other side in the same places has same oxide show. Spence, if you look at the word cent, you will see same color, which correspond with the other side upper the head and the rim. For me it is a coin with improper mix alloy. Premium for this ? NO. Your chime my friend.
Ps. Word CENT is affect for the moment only on low parts of the design.
