It has a foreign substance on it.
Its just toning/tarnish. It comes in all colors.
thanks for your comments. it could be either of those, I was thinking maybe planchet annealing issue.
Not an error
It happens. Copper is strange.

Yes copper is very strange
Ok, I get it, thanks for all the comments and pics.
Could also be contact transfer when silver coins were together with it.... such as pocket change or purse. Cheers, RickO
....that’s really stretching it a bit there..
@ambro51.... Yep... just throwing out another 'possible'...Not likely though. Cheers, RickO
back when I was young and Mercury was harmless we used to play with it and drop cents in it and coat them...
