Please help me identify this. I don't see a toolbar to attach an image -please help.

Found it on sand in Maine USA washed up from the ocean with a few thousand other rocks. I comb this beach daily for 5 years picking up trash and never saw anything like it:
 
 
Brassy metallic color
Tried it on strong magnet but no magnetic pull
Worn smooth w pitting
Density test said about a 6
Can't scratch it w a knife, scissors
Doesn't scratch a glass bottle
Rubbed it on porcelain and first rubbed dark; then nothing
Gives off odd smell like old fireworks when rubbed with fingers
Egg shaped (*many other rocks on the beach are egg-shaped)

If it smells like firecrackers, I am thinking a sulphurous origin.

 

If you hit answer to your own post here I know the tool bars appear. The bottom tool bar, the sixth box, the first icon should give you three ways to post a picture.

 

If you hit ask a question the box below the question line, same directions.
