2008 lincoln cent filled die error

Are these strikethroughs? The obverse is incused and the reverse is retained(raised).
I only uploaded pics for 2 areas, there are more. Each strikethrough has an impression on opposite side. The various anomalies leads me to believe it's a filled die(drop filling) error. Any thoughts?

All I see is environmental damage.

 

No strike through. Just Damage by the environment.

 

It appears to be a normal cent. Incuse/retained devices appear normal to me.

 

Normal?

 

Are you guys saying, environmental damage cause these anomalies? Damage put what appears to be a set screw left of and partly under the "N" on the reverse? It's embedded in the coin and raised. Tell me how damage caused that.

 

Damage can be caused an infinite number of ways.

 

That's too vague. There is no damage that will put an object in the coin in such a way that it is under a device. It would have to have been on the planchet when struck. Look at the pic again you can see a rise in the left leg of the "N". Filled die (drop filling) error. The die can be filled with a number of things, a set screw, nuts, bolts etc.

 

Look at the "E" left of the "N" the incused impression of the screw can be seen on the second bar of the "E".

 

I see what you are talking about. But I can’t make out the details around it to suggest it’s raised material from a chip/crack in the die or something else. The stain adjacent also interferes with the diagnosis.

 

What the heck is a "filled die (drop filling) error".

If you are referring to a "Dropped Element" or a "Retained Dropped Element", please explain where the element came from.

NOTE: A Dropped Element would come from the same side of the coin.

Well, it also says it could be debris as well as the design elements on the coin. I have to look it up again, but I seen one post where the dropped element came from the opposite side of the coin. Machine parts and other debris can get trapped between the planchet and die face.

 

Type in filled die strikethrough error and see what pops up.

 

I think you might be thinking a dropped letter. I don’t see that here but if you post clearer pictures we can confirm.

 

This is a zincoln (zinc lincoln). A Zinc core with an 8 micron thin copper plate.

The two metals do not go well together.

The copper plating can bubble up, create streaks, etc. It can also sink down. And that is Before it enters circulation and gets damaged and causes further deterioration of everything.

For some reason when there is internal corrosion and the damage becomes incused (sinks down), it ends up in partial circles that people think are random mint marks. It's not. It's a "zincoln"

The best examples are watching the life cycle of split plating around the mint mark. It looks like a DD but starts changing colors, sinks a bit, bubbles up, then collapses down.

 

Do you mean "see what pops up on BoobTube"? No thanks!

Wow!!!!!!!!!!

 

That little bump buy the N that you call a set screw strike through is nothing more that a plating blister at best. The copper coating on a zinc Cent is very thin and if the surface of the zinc is not 100% clean it will bubble and blister in a thousand different ways. A strike through is not raised like this is.

The coin itself has ED. Worth one cent.

 

If it is retained, it will be raised.

 

If a dropped element came from the opposite side, it would mean that the planchet had to flip over while still in the coining chamber and be struck a second time or it had to adhere to the face of the hammer die and fall off onto the face of the anvil die before another planchet entered the coining chamber. Possible? Yes! Likely? No!

Of course, built-up debris can fall out of the recesses. I didn't suggest that it couldn't be possible whether it is retained or not, but machine parts are not considered a dropped element.

Here are a few images of specimens with dropped elements that I found in a $50 Mint bag of 1980 Lincoln Cents.

Retained debris dropped from the face of the reverse die.

Built-up debris dropped from the face of the reverse die.
