Little button

[je177]

Didn't find much except for this cool little button today. It says P. O on it. I've included some pictures and was hoping to see if someone could identify what the P. O might stand for. Thanks for looking, Jim

PS

It was found in southeastern Massachusetts in an area that has been active since the 1700s.
