I'm puzzled by this resistor
Can anyone help please
1 Ohm.
It looks fine.
Have you measured it using a mutimeter?
blk-grey-blk-blk?
180?
The value wouldn't start with black unless the multiplier band was silver, and 180 would be BROWN grey black black. The grey/silver band has a sheen to it that differs from the pigment bands so is probably metallic silver rather than grey. Perhaps this color-balanced zoomed in view of it will help.
Its a tossup between:
Brown (1) Black (0) Black(0) Silver (/100) Black (
) = One ohm, with a mystery black final band (as black isn't a tolerance color)
and:
Brown (1) Black (0) Black(x1) Silver (10% Tol.) Black (250ppm TC) = Ten ohms, 10% tolerance 250ppm temperature coefficient.

You are correct, of course. I had a brain fart there. I blame it on the flu I am undergoing.
if the second band from the nearest ist band is silver, it would be a 10ohm resistor. So what about the last black band? that depents from where you got that resistor. if its from a cheap chinese powersupply, that makes sense. i have seen a lot of things like this before...
or if the second band is grey, which makes the last(Tolerance band brown making it an 80 ohm resistor with 1% tolerance)
anyway check your resistor here:
