My first impression was "TRENCH ART" from the war and could possibly be that.
Not that the war was up there but it could have been made overseas by one of
our troops and brought home and lost many years ago.
However, I have no idea of what it is. You kind of have to take something like this
and by process of elimination try to deduce what it "could" have been.
1. As old as it is, and what it appears to be, it would indicate a man had it, or at least wore it.
2. It being made out of something like brass or copper (just looking at the petina) it could have
come from a war item as both brass and copper were widely used in ww1 & 2.
3. It definitely was a pendant and was worn around the neck due to the hole in the top of it.
****Question, is her backside flat or is it contoured as the front of it is?
Lastly, what I have deduced from the above has no bearing on what it actually is. However,
if we start asking some of these questions about the item, I think it will lead you to the right
person to ask about it. Woodstock and Flinthunter both have very strong cases just from
the pictures you have given. Give us some more information about it and another thing,
was it found at a park, old homestead, out in the field and if so was it found on a hill in the
field and was there a creek nearby? The reason I ask this is I found an old Native American
boundary marker in a field on top of a hill that was very near a creek that ran through my land
where he had divided his property. It even had the river on it and it matched the curves in the
river behind my house and even showed where the lakes were.
