Have no idea what this could be. Found in a park where I found a 1912 motorcycle registration so think its quite old. Seems to have been more 3 dimensional at some point appears flattened now. Has 3 holes on one side one larger in the middle.
Only guess I have is some sort of hair piece that was plated.
Could be a hair barrette. Hard to say without knowing the size.
While I have aimed in my postings to be irenic and conciliatory, rather than polemic, I have yet endeavored to set forth the
truth, let it favor or impugn whom it might. Any notice of misrepresentations or mistakes occurring in these prose will be most thankfully received
by the author.
