Need help identifying odd rock

My dad found this rock along an old creek bed in northeast Ohio years ago. He said he grabbed it because it didn’t look like any of the other ones around it.
We found the best groove and took a chisel and hammer to it and after a couple of hits it broke in two.
Each piece is about the size of computer mouse with a total weight of 866 grams.
The outside is mostly shiny with a few dull spots. Tried the streak test but it doesn’t leave one. It’s very dense and not brittle at all.
The brownish gold color is concentrated to a certain area but it looks like there are thin bands throughout. You can see larger white spots inside that look almost smudged.
It doesn’t respond to a magnet but under a microscope it looks metallic. Theres also a tiny little blue speck I found when my camera picked it up.
Can anyone shed any light on this? Somewhere I can get it tested?

Where did you find it? Only thing I can say now is it looks like an Igneous rock. If you have college near you with a geology department they may be able to help. Another place would be if you have any rock and mineral clubs near you. My first reaction from two of the pictures was basalt but I won't hang my hat on that.

He doesn’t remember exactly where but it was in or near Lake County Ohio. Penn State would be a little drive but I could perhaps look into reaching out to someone there.

I looked up Lake County Geology and found the soils and rocks are all from glacial till meaning it is not a local rock but transported by glaciers that brought soil and rocks from Canada or gouged out the great lakes most likely Erie. Thus it's rounded shape. It's had a journey. Igneous rocks are down some 2500 feet and don't come to the surface. Here's a link to rock and mineral clubs and more. https://www.rockandmineralshows.com/location/rock-clubs/ohio
Now I have to say this. It is nothing special just a rock. :) No value.

Thanks for the reply! I have to say though, I think this rock does have tremendous value. It’s been a conversation piece between my dad and I for a long time and you just gave me something to share with him. Hearing that it’s rock that’s had a wild journey is way cooler than some piece of construction garbage. Do you know what caused the brownish accumulation? Is it a mineral that reacted to the pressure of being moved around? Sorry to sound like a ding dong but I know nothing about rocks but am very curious.
 
No problem and yes it is valuable as you say. The brownish mineral, and that is a mineral, looks like quartz and seems to be part of the rock. I'm sure it did not "accumulate" from moving around. So just an aside for some understanding. A mineral is "an inorganic, homogenous body of rather uniform composition sometimes bounded by crystal faces" , oh my college days and can't get that out of my mind. And that was some 60years ago. :) A rock can be igneous (molten once), sedimentary (laid down from erosion) or metamorphic (changed from heat and pressure). A rock like granite (igneous) is composed of minerals as are many other rocks. Sandstone is composed pretty much of quartz. Slate is a metamorphic rock formed from pressure (compaction) of some other forms of sedimentary rock.
 
This is non-metalic, anyone know what it may be?
