pulled these out of the ground. Rocks that ping as metal and are non-magnetic.

They have a black glassy look. Any information would be great.

The top right picture in particular looks like Galena. (which will be metallic under a detector)

What is Galena? I will show some better pictures.

Galena is a lead ore - I agree with that guess , are they fairly heavy ?

you might of hit the mother load if it is indeed ore. It does contain a small bit of silver and is currently being mined for that and other uses. Are you the property owner or was this in the middle of a subdivison/populated area?

I agree that it looks like lead ore. I've found some around here before

No, not heavy at all. Really light weight.

I think what you have is Coke

Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product.
