Curious of the age of this button found it a few days back a MID water line burst and brought up a few bronze items which led me to start sifting and metal detecting the area. But anyways this damaged button is what I'm curious about if anyone knows anything let me know please all info is much appreciated as always I'm always thankful

The only thing I found was that Prym is a German company and has been in business for a very long time.
