I'm new in the forum and maybe this is a question that somebody answered already.
I wanted to know if there is a difference in prices for the new shining copper and the oxidized one with dark/dull color. I have some copper wires but because it is old and maybe left in humid places, its color is not anymore golden bright and large parts of it have the characteristic bluish color.
Do the yards make a difference between them?
Any reply will be appreciated.
