Help with raised Number brass button/tag/disk whatsit?

[gitterdug]

Anyone got an idea what this is? I found it on a site that has military relics from 1850 or so, but I don't think it is military. The numbers are pretty stylized. The item is brass, and it is cast. The numbers are raised. The edges are not completely rounded over, but there is a "lip" edge. The center nub on the back appears to have been bradded. The thickness would be about right for leather I think. The little nub at the top of the back side is rounded, and I don't think it was ever at a point. Obviously, that added nub would suggest it was meant to keep it in place, and I would think it would be within a hole of some kind. Another feature that kinda struck me, was the hammered face

I think it might be railroad, or from a hotel, perhaps on a piece of leather for a key holder.......anyone seen one of these before? Know what it is? Thanks and HH

It looks like a clasp that is used on leather like a saddle bag or horse tack.

I think they used them on canvas bags too.

Oh I just remembered an old holster used that type of fastener.

Might be used on this type of leather fastener....

This 884 is the size of a half dollar on the front. The back has the bradded portion. But, I appreciate your hard diligence....
