What's going on with the rims of this indian head cent

I have this coin with great detail, but has obvious issues. But the rims are huge and I don't know why? I'm sure it's not an error or anything just curious what may have caused this?

a lot of times encased cents have rims like that
^^ I was gonna say, think "lucky penny" holder or something like that.
