(Sorry for the bad quality, I'll see if I can take a better one.)
Hard to tell from the pictures. If it looks smooth and shiny like the rest of the Gill plate it could just be part of a pigment change. Goldfish can change their colors quite a bit.
If it looks like a hole you might have a problem, likewise if it looks fuzzy like a fungus.
