Can you please post pictures. If you hit the edit icon, your original post will pop up. Then using the first icon of the sixth box from the left of the bottom tool bar, you will get a drop down giving you three ways to upload photos into your post. Make sure to save to server. Voila. Photo in post. Look forward to seeing your space rock.

Type meteorite doorstop into your browser. Meteorite fell into farmers field in the 1930's. It has been a 23 lbs. door stop since then. Probably worth as much as the farm. Said to be worth at least 100 grand.

i had to get on laptop as i was on the site on a smartphone and it doesn't give those options. But thank you very much for the reply. This rock is 3.8 lbs and approx 5 inches in length and about 2 to 3 inches tall. It feels pretty heavy for its size and i have to guess it was found in a field in Arkansas as my grandfather has been gone along time now. It has been used as a doorstop as well for the past 20 years. I have looked at 100s of different pics and never found anything like it.
i have posted a couple pics. I hope this helps identify it. thank you Weasel.

It passes the look test. It should be magnetic and very heavy for its size. Let us know if that is true.

Its heavy for its size yet not magnetic. It appears to me like lava laiden with gold strands or very small fibers of gold. 3.8 lbs. and ive not seen anything like it.
I have added a pic for size reference if matters.

It definitely looks like it could be a volcanic rock, but I have no idea what the gold coloring could be. Can you take a close up picture of the gold patterns? May very well be a meteorite.

I've added a few pics up top to the original few. The brightest places on the rock are gold strands. My cell struggles to take a close up. The top two angled sides of this thing are showing the gold strands and thru the years of light handling and weathering whatever it was placed in or on shows wear. the bottom where its sat all these years continues to be just dark lava type rock. Nothing has ever shown on your hands however like charcoal or staining of your hands if handling it. i have put a pretty strong magnet right on it and got no sense of magnatism. So the mystery continues. All i know about it is that its heavy and appears to be lava with gold strands showing thru the wear on the top 2 sides of the 3. its not magnetic and 3.8 lbs which is heavy for its size. the story is that it was found possibly 50-75 years ago and left to me. its always been referred to as the space rock.
If there is anymore input its much appreciated. I still have yet to find anything like this.

So, I think it is not a nickel/iron meteorite. It would be great if you could take it to a rock shop or a lapidary and cut a slice to see a cross section. I still think it is volcanic rock, probably basalt, but I am not an expert. I see what could be some burning but I am not prepared as yet to conclude this rock entered our atmosphere. Weathering of meteorites can cause the specimen to lose some of that

If it's not magnetic, it's not a nickel-iron meteorite as those are magnetic. It does look like some sort of sulfide. The color is perhaps a bit too silvery to be galena, which it does look like, but perhaps its galena with pyrite. Some less common suggestions may be nickeline, pentlandite, or some sulfosalts. Without seeing any crystal faces, streak information, or hardness, its really hard to identify this without any tests. I'd suggest at least doing a streak and hardness test to try to narrow it down.
The only other thing I can say is that the gold may be a form of pyrite, on a volcanic matrix. Try taking it to an expert if you can.
