Money clip or something else?

Dug this in a Civil War camp deep in the ground and @ first I thought it may have been a money clip but I just do not know... Only thing it says on it is Pat appofor?

In observing a number on a collectible, we are not always looking at a patent number. If the number has a D in front of it, this designates it as a design number. However, few design numbers carry this identification. Often looking at the piece will determine the difference.

let me throw a question out there hut, the loop on your chain there looks to me that 1 side opens if you squeeze it , does It ?
maybe that will help on the ID , because if it does open then its made to go into a item that has a hole , like a o-ring on a pocket watch .
