First Button but stumped

[Bringerofthepast]

I found this button on a farm in NJ. I'm super new at detecting in general so knowledge of material and other helpful info will be learned for future posts. The first two pictures are of the button and the third is the scale. It's in the middle on my desk calendar.

Ive never heard of someone finding one in America but in England you can find things called livery buttons. I pretty sure they were used to identify a horse or other animal. With a lot of research you might get an exact ID on who owned it.

They were worn by the servants to show which Family you served.
Seen a few turn up in the US. Most of them are the flat buttons circa 1830s, this one is a 2 piece late 19th C type which are less common, as they were going out of fashion.
