It looks like brushed hardware. The brushed pattern is very uniform across the whole plate so it doesn't look like it's scratched. "brushed" refers to the plate having a "matte" effect instead of a shiny (polished) effect and ruthenium is the metal used to plate over the brass(?), so they have either gold plated (gold), palladium plated (silver coloured) or ruthenium plated (dark greyish colour). But I agree with bag snob, it looks like the plating's come off. msjackson, would you by any chance have applied any sort of metal polish on it (like some kind of 'Brasso')? Otherwise it might be the plates scratching against the 2 strap holders over time. Luckily H can replace it!
