Milk Spots

It seems to me that ASE's that are protected or highly graded are the only ones that have their value affected.
Since they were originally meant to be bullion coins, perhaps that is the best mindset to have, in which to collect them.
Therefore buy them raw, UN encapsulated or slabbed, and where MS60 will suffice.
That way, minor marks will not detract significantly from their value.

I do not think there is very much numismatic significance in owning a highly graded bullion coin.
Be like Scrooge Mc Duck, and swim in them! I don't think HE bothered too much with slabbed or encapsulated coins!
Get up close and personal with them. Store MS60's in tubes or flips if you wish.

Proofs are meant to be a thing apart, and thus are marketed as collector coins. A problem exists if they have milky spots, especially if they were sold encapsulated.

The problem becomes one that needs to be solved by the Mint, in terms of quality control, both of the coins and of their packaging.

However, the 'horse' has already bolted when it comes to existing proof coins. That would leave un affected proof ASE's at a premium.

I dont think I have a proof that has ever gotten these milk spots. I havent looked but no, I dont think so.... guess I have another reason to dig into the vault and look at each and every coin.... *prepares rations and drinks for an unspecified time period*

I have a 1964 dime in a proof set with a milk spot so this is not a new phenomena.
I looked in the glossary and found no entry for 'milk spot.'
A chemical wash sounds feasible.

I think I'm no longer going to pay money for graded ASE. Ungraded for me from here on out, unless it's a deal I can't pass up on. Thanks guys forgot our info.
