What's this on my Buffalo Gold Proof?

There's a faint whitish crescent of haze at the lower tight rim of the portrait. It is not visible at certain angles and I like the coin, but I'm curious about the nature of this "discoloration."
The coin is a PCGS PR69 DCAM. Normally I shy away from bullion related items or anything modern, but I couldn't resist having at least one of these in my collection.

    In my scientific opinion, it looks like crud.

    I can see what you mean, based on the low quality scan, but it is not debris or dirt accumulation of any kind. My "unscientific" observation made use of high magnification and strong light. When tilted, this haze is not visible.

    I would have guessed schmutz.

    New collectors, please educate yourself before spending money on coins; there are people who believe that using numismatic knowledge to rip the naïve is what this hobby is all about.

    You may be correct. I will have to do a literature search.image

    How about cruddy schmutz?
    I suppose I deserve this, considering that I'm examining potential flaws on a bullion coin.image
    Seriously, I was thinking that it could be some kind of rinse residue during proof production at the mint.

    I dunno. Looks a tad hazy to me. Perhaps a little hazy cruddy schmutz? I sometimes see that faint hazy cruddy schmutz near the lower right rim on US Mint packaged products. Maybe this one was in the US Mint packaging long enough to develop a touch of hazy cruddy schmutz?

    Anyways those proof gold Buffs sure look awesome!

    Looks like a radial dusting of 'cruddy' Schmutz beer residue!!

    Buffalo milk spot, which is different from eagle milk spot.

    The same stuff in the same area was on one of my mint issue $25 proofs.It came right off with acetone (and hasn't come back.)I also recieved a unc $50 that had a 1mm black dot on the Indian's cheek.When I removed the dot of debri with compressed air there was a corresponding pit left on the coin so I guees some debri got between the die and blank(that one went back).

    "What's this on my Buffalo Gold Proof?"

    whatever it is, it's covering the missing PR1DCAM

    I have noted some areas of irridescence on about half of my buffaloes.

    I think my topic is doomed to failure.

    Anyway, at least the "milky" stain isn't anywhere near the Bison.image
