Interesting, and maybe the center piece of some type of buckle. Someone should know the answer.
Judging by the looks it appears to be stamped brass and not pewter.
I checked Kerksis last night, and though admittedly incomplete as virtually every known source is, there is not an example of this object. I still think it's a top to a small tin where the skirt has fallen away at the solder joint. Carefully looking at the reverse you'll see spots where it is rough; as well, the die that made it stamped down the outer-most perimeter of the piece on the reverse (which may acccomodate a skirt) which is the opposite proceedure you'd see if this was a mounted plate encompassed by a backing. It would be too early (15 stars) for percussion caps, but it could have held a number of other things for rifle or pistol, or even cheap snuff maybe. It's a very cool find, that's certain.
Is it my eyes or is this thing concave? And, is that a pouch attached to the beginning of the banner at the top? Also, I count 15 stars. Is there any significance to that number? One more thing I just noticed; the motto reads "Pluribus Unum" The "E" is missing. I bring all of this up in hopes it will lead to an identification.
OK. I can see clearly now. What I thought was a pouch is part of the banner. This is a very interesting piece and I hope you get a proper ID on it. However, I have nothing more to add. It has me stumped.
