That is a die pair which never made enough during its' working career to have a comfortable retirement - the numismatic equivalent of an 80yo Walmart greeter. It should have been retired 100,000 strikes ago.
Dies are employed, of course, in obverse-reverse pairs. They don't always live their entire production lives together. Sometimes one will fail early, or a clash will happen and they have to take one die out of production to polish the clash away. So, you can sometimes see this worn-die effect on only a single side of the coin. Your obverse images clearly illustrate severe die wear. The reverse image is less talkative, but above KISATCHIE looks to be a similar indication. It makes me think this particular die pair stayed together for their whole lives.
@annacrigger First, welcome to the neighborhood, Anna! The wear Dave is referring to is commonly called "die deterioration". Chris
Welcome to CT, Anna. And thank you for asking what you termed a silly question. I learned something from Super Dave's answer, too. Remember, there aren't any silly questions...wait, that's not true. I took a computer class once. I think my instructor would disagree with that old cliché. Steve
