Hello folks,

Found this today. The first two photos are both side. The last three please look adjacent to thumbnail for small characteristic patterns.

This is what I found Online.

To find out if a rock is a meteorite, look for the rock to be black or rusty brown, which shows that the meteorite has either just fallen or has been on Earth for some time. Next, determine whether your rock has an irregular shape with rounded edges as this is the typical shape of meteorites

And then this;

Regmaglypte
Description
Noun. regmaglypt (plural regmaglypts) (astronomy, geology) A small, shallow indentation or pit on the surface of a meteorite, resembling a thumbprint impression in clay, created by ablation while falling in an atmosphere.

First two photos relate to first paragraph. Last three adjacent to my thumnail has me curios of second paragraph.

Thanks folks.

I have tons of photos that resmble mine and less of higher quality that resemble yours..thats a photo offline btw
 

Thats polished as well...
 

Its alloy and has all characteristics from articles

If you have a photo that you took first hand or authenticated and can detail describe that dismisses mine by comapre and contrast with details. That's what I am looking for.
 

It looks well water worn. The only way to know for sure is to get an analysis of it made.
 

@Edgychris… the website that you got those 'tips' from is painting a picture that is far too simplistic. Not all meteorites have regmaglypts and those of the type @Kray Gelder is showing only occur in certain meteorite types. This is more typical of what is more commonly found (my collection, rusted, unpolished):

This one has no regmaglypts at all (my collection, unpolished with some fusion crust):

I have collected meteorites for 40 years and I have to say that your specimen does not exhibit more than a passing resemblance to a meteorite and the depressions in it likewise. Nevertheless, it's not possible to identify most meteorites from pictures alone.

Start with the basics. Is it magnetic and if so how strongly magnetic. Streak it on the back (unglazed side) of a ceramic tile. Does it streak readily or skid off the tile. If it streaks, blow away the dust and tell us the colour of the streak. You say "it's alloy". Alloy of what? If a meteorite, it will have a significant content of nickel and the rest will be almost entirely iron. Very little else. The yellowness of the corrosion products is not a good sign.
 

Upon further inspection, I see some sort of fossil embedded to the left of your thumb. That would be a first, for a meteorite, for sure.
 

I would say the easiest way would do the 3 test for meteorite, go to Robert A Prizker center for Meteoric and polar studies, it free and only cost the shipping and return shipping, if you want it back either way make sure you send a return box or envelope. I have sent 2) so far that passed there field test but still were not,99.9% turn in are not meteorites, but you never know till you send it!
 

Your rock contains obvious shell fossils. You have a bit of studying to do.

Time for more coffee.
