Please see the attached photos. If you look at the reverse,
everything that should be frost, is. If you look at the obverse,
nothing is frosted. Isn’t that odd? I had this coin certified myself
by ANACS, and it
came back Cameo. Now, I never have coins certified by ANACS, but
this time I did. When the coin came back as Cameo, I called ANACS to
find out if perhaps they don’t have a Deep Cameo or Ultra Cameo
designation, but I was advised that they do. So, I reexamined the
coin, and sure enough, no frosting on the obverse (which is a little
odd). I checked all the photos carefully on eBay, of all the
Numismatic Guaranty Corp. and Professional Coin Grading Service
coins, and sure enough, none were frosted on the obverse (which is
odder still, that NGC and PCGS automatically issued UCAM and DCAM
designations). I would really love to get to the bottom of this.

An examination of the photos of your coin appears to show frosting
that is typical for a Proof 2015-W American Eagle 1-ounce platinum
$100 coin. However, rather than trust just our observations, I
forwarded your inquiry with the accompanying images of the coin
encapsulated in its ANACS slab to the U.S. Mint’s Office of Corporate
Communications which, in turn, sent your questions and images for
evaluation by U.S. Mint production specialists.
Here’s what the production specialists had to say:
“The 2015 Platinum Proof coin used the same standard finish as we
have in the past years on all the obverses — laser frosting with proof polishing.
“The obverse is frosted with a polished mirror background. There are
two levels of frosting — heavy frosting on the letters and a light
frosting on the design elements.
“The United States Mint has compared 2015 Platinum Proof coins to
the original design and found the coins meet the intent of the design.”
While the level or type of frosting may not match that found on
older Proof American Eagle platinum coins, it does appear to be present.
