Vintage Pulse member Deborah B. writes "After a little googling I figured out that P of H means Patrons of
Husbandry, which is The Grange. After a lot of googling and looking at
lots of pictures of Grange paraphernalia, I have yet to find another
pin that looks like the one attached.
From looking at other organization pins, it looks very much like the style of the early 1900s. But that's all I've got.
Can anyone shed any light on this pin and give me an idea as to its value?
It does not have a silver mark, but appears to be sterling. The design
is etched into the metal and it is enameled green. It measures 11/16"
x 3/4". The pin back is simple with a 'c' latch."
