Mint mark question.

[BC1969]

Would anyone be so kind as to tell me what a mint mark like this is called.
Filled?

On the same coin, one of the . Is deformed.

What you see is a combination of wear from circulation and more than likely Post Mint Damage, even on the Mint Mark.

Thank you so much for taking the time to help me learn about this.

Yep, as the coin is hit the metal can be slightly moved around.

What's the year on the coin, Morgan I presume. You have to take into consideration the age of the coin, the "s" mint mark could be a badly worn Reverse.

It is 1879.
It is pretty worn, but I've seen worse.
