You said on your previous post that someone told you it was a meteorite. They were wrong. It isn't. I guarantee it 100%
You also said you had been told it tested positive for gold. Maybe it did. It appears to be a schist, so it's possible, but none of us could say just from looking at it and unless you can see veins of gold running through it or obvious pocket accumulations it's not likely to have significant value.
What should you do? Probably use it as a doorstop.
