Not for sure what it is. Can anyone help?

It's not magnetic, very heavy, and hard.

1st - I noticed this was your very first post - so, Welcome Aboard Rock Tod! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forum: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) - members may have more success helping you (your location may help, etc.)...

2nd - I moved ya from HELP! over to ROCKS/GEMS for more exposure.

Looks like a clinker.

Did you find it near a railroad, refinery, blacksmith shop or smelter?
