Found this in a vacant lot where the coins have been mostly 1910 to 1965 or so.  Any ideas?  Seems like a pin, or what looks like 2 broken pin anchors.  Feels like cast; it's heavy.  Merc for size

Little big for a typical pin. Is it zinc?

Looks like an USA military cap badge going by it shape W x H and size.

It's not US military issue. It could be a WWI or WWII era patriotic brooch or pin, or military retirement pin.

it is heavy...a cast item, i think with a most gone plating, that shows a bit on the back.  I also think it is not military, and more along the lines of patriotic.

Might be leaded pewter. Zinc usually bubbles up. Probably cast with a rubber mold on a centrifugal casting machine maybe 70's.
