Interesting, I can vote for 4 of them and not be sure without the other details.

 

Please give others the chance to answer.

 

Man, you don't give us want-to-be experts a chance, shucks.

 

I won’t say so you have a chance. Lol

 

I think two of the four you're thinking of are equivalent, but the way the press works, one of them is not technically possible.

 

Well, I voted for weak strike, out of tolerance planchet and low pressure strike. I am leaning toward out of tolerance planchet, though, because the unstruck area of the breast bears what I interpret to be planchet marks that were not obliterated because of the lack of metal fill.

 

I better get close on at least one

 

Shoot.......looks like good old wear to me, but maybe I'm out of tolerance. PMD

 

I'm going with strike through because the best feathers seems to have been struck well. The planchet seems fine from that image, and if it was a low pressure strike I believe that the center wouldn't be as well struck.

 

I haven't even voted yet. I plan on waiting.
You are right @messydesk one of them would show at the perimeter of the coin, not in the center.

 

I won't type what I was thinking, as Publius has stated it much more succinctly!

 

That was my thinking also.

 

Answers PLURAL!

1. Strike Through. No. OPSI (original planchet surface impact}marks present on the surface inside the low area
   
   
2. Capped Die. No. Nothing in the image suggests this.
   
   
3. Post Mint Damage. No. Totally original undamaged surface.
   
   
4. Planchet Flaw. No. No evidence of planchet metal filling a defect.

All good answers: Weak strike; Out of tolerance planchet; Low Pressure strike.

What would cause a low pressure strike?

 

• Insufficient contact between the dies and the planchet caused by either
  • Thin planchet
  • Improper die spacing
• Improper annealing of planchets before striking, which would require a higher than normal striking pressure
• Incorrect setting of the pressure adjustment wedge within the press before production

Is the subject coin a 1940-S? Those seem to be the pancakes of the entire type.

 

I don't remember the date. It is an "S" mint in the lower 40's.

 

You got to be more specific. Is it 4 or 6. I choose 6

 

That sounds like the answer to me.

 

That why we need the whole coin picture
