What is this?

[True_Metal]

I found this as a kid in central Illinois.

It is a piece protruding from the ground that i kicked off a very much larger piece that was still buried.

It came from a field on the outskirts of Peoria.

I have owned this for over 35 years.

It has blue and purple hues in sections of it. It scratches steel and is very heavy!

any ideas?

If I remember my college geology days its Galena.
Galenagəlē'nə or lead glance, lustrous, blue-gray mineral crystallizing usually in cubes, sometimes in octahedrons. It is the most important ore and the principal source of lead. It consists of lead sulfide, PbS, but frequently contains silver (it is mined for this metal in some localities) and other accessory metals. It is widely distributed throughout the world, occurring in veins and in bedded deposits, in Missouri, Idaho, Iowa, Wisconsin, and Utah in the United States (leading producer of lead) and in Australia, Canada, England, France, and Mexico. Galena crystals were once much used in radio crystal sets.
Nice find. HH Don

If found in Illinois, probably Flurorite.

Pretty mineral there, True, Kinda looks like Fools Gold though. Otherwise known as Pyrite. see pic.

I once worked at the Bunker Hill
mine @ the Lucky Friday mine in
Idaho. That sure looks like galena.
If it is heavy that would be a pretty
close bet . Jim.
