Appears to be a skull with a helmet. Snake? Wrapped around it. Arms crossed in the front. Could be lead? Seems like it's not heavy enough. Found in a park where some homes used to be.
I think it's the handle to a decorative type dagger, hopefully this link works: vintage mummy handle dagger - Google Search
I was a dumb enough kid to use my Mom's letter opener as a throwing knife Once, with the same result... Perhaps it met the same demise.
