1941 D Strike Through Error?

To the forum.

This looks to be what is called a lamination error.
This is a defect in the metal composition of the planchet
which causes an area on the coin to be lifted up from the surface. This is a small one so not really much of a premium
if any on the coin. Some are larger and different shapes and some are lifted way off of the coin as well as they can become detached completely from it leaving a groove or trench on the coin. There are different terms used for these laminations so do a little searching on the forum for them if you like. Struck through errors as you may or may not already know somewhat about, are caused by some sort of foreign object or debris that was present on one of the dies
when the coin was struck. You can have an image of the object on the coin or even the object itself like say a staple or piece of wire etc. actually imbedded into the surface of the coin.

Thanks for the information! Good to know.
