Help with button

[tmac2301]

I found a button today that I can’t recognize. It is stamped test twice around it and has stars between them. The pic is hard to tell but hope I can get any feedback on what it is.

If you could tell us the size and show (or describe) the back it may make a positive identification easier.

It’s the size of a penny. It’s like the back part is missing. The edges cup around

I'd guess that was a work clothes (or overalls) button, from somewhere around the 1930's-40's, with Test being the brand name.
