This is a mineral site, so I'm not sure that anyone here is going to be of much help with ID'ing a meteorite. Aside from that, I'm not sure that even someone who was knowledgeable in meteorites would even be able to tell based on a picture of the outside alone. If it were sliced so the inside could be seen, it would be more helpful. It just looks like a chunk of melted metal or slag to me.

This is also a non-commercial site, so even if someone does know that it's for sure a meteorite, no one here will give you estimated values. Asking for and giving price estimates is against the forum rules.

Hello. Although this is a mineral site, we are asked about meteorites....and meteorwrongs fairly often.

Compositionally, meteorites are either metallic or stony. If metallic, they are magnetic.....you should test that, but this does not look metallic in your picture. It looks compositionally complex, which is not typical of stony meteorites.

A meteorite normally has a fusion crust and "ablation surfaces" from passing through the earth's atmosphere. I see no crust here, in fact it looks highly polished... and although it has a number of scalloped surfaces, at least one has angles that are too sharp to be ablation related.

I am afraid this adds up to it being a meteorwrong.

I know something about meteorites, though I'm not an expert. You'd have to tell in what kind of place it was found - on/under ground / in sand or other place. Is it magnetic? Do a specific gravity test [how to is described on this website]. Yes, seeing inside and etching with acid would be better - but that is not easy to be honest -but break off a small piece with a hammer and chisel and take photo of that broken surface. There are meteorite websites and experts on them that have websites. It doesn't seem to have a fusion crust, so either is not a meteorite or the crust has been eroded away [often happens over time]. It looks and sounds metallic, but by testing Specific Gravity, magnetism, and perhaps hitting gently with a hammer you can decide if it is metal, stone [or mixed] - some meteorites are both. Just looking at it is a very hard call....it could be - but I'm far from convinced it is, or it could be just a heavy rock or chunk of water worn or wind/sand worn metal from some man-made activity. As said, this is a non-commercial site, so no one will tell you anything about value. However, if it is a meteorite, you should be very proud - suggest you test and/or talk to specialists on meteorites who will likely also tell you to test or send to them for them to test. Some of the surface looks like rock to me. Maybe in a large city near you there is someone who specializes in meteorites at a university or museum. Meteorites are rare. If you found it, see if there were reports of others from that area and what they looked like. While individual ones can fall, often they come as a few to many at the same time.

I totally agree with what Kushmeja says, and I just want to add that after many problems in the Spanish side of FMF about this kind of requests, we decided not to talk and stop talking about meteorites there, because whom proposed them tended to insist until to exasperation, basically because many times they just wanted someone to say that they could be right in order to use that answer to sell the rock and take money for it.
If this also happens here, we will not hesitate to avoid the "meteorite" topic altogether and block the posts that talk about them.
