U.S. Pin, Any Ideas on It?

[coinman123]

I found this earlier this year. Any ideas on it. Is it WWII, WWI, Korea, Vietnam, or not war related. I found it in a Tot-Lot on an imformal hunt, if it is war related I'm guessing a kid brought his dad or Grandpa's war pin wear at school, or something like that.



Thanks for Any Info, Coinman123

That style of pin back on a collar device is WW1 era, pretty nice find and in decent shape too.
