Does there appear to be any writing on it? Consider laying it flat on a background that helps viewers discern obscured characteristics. Too, consider placing it close to a known object like a quarter or a dime. Perhaps offer some accurate measurements.
Whatever it is, with good photos and descriptions, someone on this forum WILL identify it for you! This is an amazing group of people.
No worries, I am too blunt for my own good sometimes. Im not sure about your item, Possible a pocket watch fob piece of some sort. But thats a serious shot in the dark on my end.
Tough call on that one. Even with so many knowledgeable people on this forum, sometimes the bits and pieces are just tough to identify. Maybe someone will still come along and nail it for you. I was going to say it looks like a diary lock, that is missing the top lock loop. But if there is no place for a key on the face of the item, then thats not it either.
