"Gold dusting flakes"

Was wondering if anyone had any idea what the problem is with this lens? Seller calls it "gold dusting flakes".
Looks and sounds more serious than just dust to me...

Just curious, I'm personally not that interested in buying it.

Looks like the front element multi coating is worn off. Too much cleaning, I would say.

My DA 16-45/4 has something that I might describe like that. It looks like someone took off the front element, sprinkled in a few gold flakes, then reassembled. The flecks look like they are part of the plastic surrounding internal elements, not on the glass like dust. I got it used so who knows if it always looked like that. After some careful examination, I ignore it.

I'm wondering if it's some form of detritus thats gathered in the lens through use - dust, pollen? - thats gravitated down to the inside of the front element when the lens has been stored mount upwards?

If it is a simple service would remove it. Could be worth a gamble at the right price, but caveat emptor.
