U.S. buckle or something please help identifying...

[Rooster11]

Found in Upstate New York when you flip it over on the back side the rust spot is directly above the U.S. can anyone please help me identify what this is? Thanks in advance!

If there’s lead in the back it may be a horse rosette
1850s 1870s ( that is only a guess )

If it's lead backed like that its definitely a bridle rosette for a horse.

Nice find!

That block lettering is the key to the date of that rosette. Welcome to Treasure Net!

It could also be a uniform collar disc. You should re-post it, with a quarter of half dollar coin as a size reference. That would help a lot. If it is lead filled on the back side, then it is not a collar disc, and I would go with Rosette.

Looks like a jacket button on cuff or for an epaulette or shoulder of military uniform- officer.

I agree with the horse rosette, but I thought this lettering style was Post-CW, circa WWI. But thats from memory, not looked at any references/books.
