Heating is a chemical procedure. The spots are not made of gold (usually), so heating affects the spots, but leaves the inert gold unaffected.

I received the four 1997 gold small date 1/4oz back today.  NCS did a good job with the removal of copper spots and all four are graded MS69.  I posted the before pictures previously, but here are the before-after picture for 3614937-002.  First photo is before, 2nd is after.

Another before and after.  This is 3614937-004.  I'll upload all to CC, but I thought I share some with the CCF members.

I watched a you tube video about this, they removed the red spots with the flame of the lighter

Be very careful how you do this. You can fuse residue and dirt to the surface - take my word for it!
