Pin of some sort?

[Beachmom5]

I found this a few weeks ago , was partly buried in mulch . I was thinking maybe a pin but back isn?t super sharp. It looks old to me. I actually collect antique pins as hobby but am not sure this is a pin as there’s not a catch on it. The pin like part rotates. It is decent weight , to me looks hand painted and has a vintage look to it. It’s about 1 inch. Thanks
