I'm not giving an opinion, because I do not know what it is or isn't.
What I do know is thst you should find a Rockhound or someone who knows geology and can look at it in person.
You can post a handful of genuine meteorites here and get a bunch of opposition from people as if all meteorites are the same. The fact is there are many kinds of meteorites and many factors that can cause them to age differently.
Good luck, I hope it turns out to be really valuable. If not, hopefully you learn something along the way.
