✅ SOLVED P.N.B&G. Co. Button or Maybe a Cloth Rivet? No Clue!

[FreeBirdTim]

Digging at a 1920's bottle dump and found what appears to be a button or rivet. It measures 1 1/4" in diameter and is brass on the front. The back is made of iron. It's embossed with the word "success" and has the letters P.N.B.&G. Co. on the front. I think those are the letters, but the "n" is kind of iffy. Maybe a button or some sort of cloth rivet? No idea. Any help on what it is or the company that made it would be appreciated.

Here's a couple of pics:

My guess is it was a sew on snap button.

Further research: The company lasted from 1901 when Nickolas Kopp--Kopp Glass Co. --took on additional partners and renamed the company PLB &G. Co.
That company lasted till bankruptcy in 1926 when Kopp reorganized and called the successor company Kopp Glass Co. Inc.
