Another Question about a 1920 D Lincoln Cent 1 1

[Mr.Bill347]

This 1920 D Lincoln cent has what appears to be Extra material just above the Date and Below as well.

   This appears to be a planchet lamination (little or no value). It's not clear to me that the coin has a mintmark.

[Just Bob]

Could that be a 1920S?  And, could that be glue, or something similar?

[powermad5000]

Hard to tell if that is something on the surface, or if it is a lamination. Bill says it is raised, so either thing could be raised. I think I see an S mintmark if you look hard enough in the area, but even whether D or S, other than for proper identification, this cent in VF either way it would not make much difference in value.

I suppose if it is some kind of glue, a short dip in acetone would solve that problem.

[Henri Charriere]

The 2 took the brunt of the hit. The 9 and 0 appear flattened.  Localized collateral damage.  No evidence of any mint mark.

[Mr.Bill347]

Just Bob I think you are right. I can see the S mint mark now! Thank you!

[Numisdoclaw]

Definitely appears it took a heavy blow, and the weight of it remained as it exited rolling metal as it left.

Looks like a damaged 1920-S, the line that passes through the numeral 0 is too straight and clean.   Laminations are seldom that straight and with a clean edge.
