I can't get this to photograph like the color it looks in person. It seems to look kind of like a graphite gray color very shiny so it makes it photo appear lighter than it is. Just curious to know what causes coins to be this color.

Environmental factors. The Cu/Ni tones differently depending on what it's exposed to.

Likely heated. No premium. Nickels will be found from reddish through brown to jet black, plus painted, plated, colored, inked, holed and split, served from a pit or on a BBQ spit.....
