Error Or Not? 1938-1357 King Farouk 2 Millieme

Struck thru? Maybe. One way to look at this is to consider the negative of the coin (the die)
Let's say there was a normal 7 on the die. If a foreign object got between the die and the planchet, and was soft enough to be pushed into the coin, I would think the 7 would still be well-defined because it's on top. But on your coin, it appears as large, rounded mark that does not resemble a 7. The die could be like when a tooth has a cavity, and if it bit down on a coin a larger mark would be left.

Out of curiosity, I took the other digit and moved it around to suggest where a normal 7 might appear--although I could be wrong! It's interesting to see the mark is much wider in some areas, and in other areas there is an absence of anything suggesting the 7 digit. So if it's not damage to the coin, I'm guessing this mark was on the die (but in negative relief--like that cavity).

If I understood your words Kurt you are suggesting;

die break
An area of a coin that is the result of a broken die. This may be triangular or other geometric shape. Dies are made of steel and they crack from use and then, if not removed from service, eventually break. When the die totally breaks apart, the resultant break will result in a full, or retained, Cud depending whether the broken piece falls from the die or not.

Hi,

The relevant parts of the pictures show minor die chips and they are a result of the die wearing. One of them is large enough to perhaps be called an interior die break.

In any case, these are factors of die wear that indicate that the die is wearing. None of what you see would be considered as errors since they are a normal part of the minting process. Dies wear, yet they are sometimes used until they can be used no further.

Thanks,
Bill

Thank you Bill

These are the pics and description I used before;
I have 3 Egyptian one pound coin baring King Tut burial mask with some differences.
The traditional nemes head-dress of the mask has yellow horizontal stripes and a vertical stripe on the inner side on both sides of the ceremonial beard.
At the end of this vertical line there is either a "L" shape thickening on both sides, on one side or no thickening at all.
No variety is listed for this coin in my Krause.

on both sides

Pardon my ignorance, but which gallery?
