Newbie coin searching found this nickel. It’s clean but very dark black looking. Help appreciated!

This coin seems to be nice and somewhat clean but blackish? Help appreciated

1958 is a MUCH harder date to find in circulation.
Your coin likely had an improper alloy mix to begin with, and has maybe suffered some light corrosion along the way.
No real value above face, but a very rare circulation find.
K, thank you! It’s like charcoal black! My first for me
Maybe it's just from being handled over time ?

The nickel gives the appearance (somewhat) of an improper annealing... “sintered.” IMO

Thank you for the link. looks to be a black beauty coin!
Disagree with handling. But thanks for a thought! Jim night
Did research in minutes and found improper annealing planchet. Thanks to Hemispheric!
Check the edge. If it's the same dark color as the coin, then it's likely to be environmental damage. If the edge has the coloration of a normal nickel, then it could be struck on an improperly annealed planchet. (I learned this trick from an old Fred Weinberg post)
Probably improperly annealed (as mentioned above)...the term 'sintered' is incorrect and should not be used in reference to a coins surface. It originated, mistakenly, since it was thought to refer to color - it does not. Cheers, RickO
Nice Jeffy. This is my Jeffy, similar to your's. Mine's a 1959. For being 60 YR.s old, most steps are still there, as your's also.
