Unknown Button with unknown material

[Btoots]

First off thanks for looking. I pulled this out of the ground a few months ago and didn't think much of it until another find I posted from the same area was identified as Rev. period. I'm certainly not thinking that this is anything close in age, but I thought I'd get some help identifying this. Measures exactly 1 1/8 across. The front is pressed onto the metal backing and although it's not, the front feels like wood as opposed to plastic. Definitely not plastic or bakelite as it does not have the feel of a smooth or hard finish. There are no makers marks or anything imprinted on the back, just a through hole for attaching to a garment. It is also a bit more brown than the pic shows bit it's close. I got no clue. Any and all opinions would be welcome, thank you.
