i found this button at a 1880-1940's home site i'm guessing the button is in that time period and the back is blank i think its a snap button . thanks, Gold boy
I tried to find something, Gold Boy. Unfortunately, you put eagle, and phila into your search, you know what's gonna come up, and it ain't an old brass button. Sorry.
Goldboy-
I think I can solve this one... I have found a few different suspender snap buttons from a 1912 logging camp among the brands I found was “Eagle” but most of my other suspender buttons say the work “Make”
“Capital Make” “Chester Make” “Crown Make” The “RG” one still has the Leather end attached
Here is a pic of suspender related finds including a fully intact leather end with button.
I also found ads from 1856 that mention your particular brand “Eagle”
I think your button is from the early 1900’s. Here is a 1912 add from “Eagle”
