appreciate help for first timer. Please explain milk spots. Do they appear on unc. w; reverse and proof ASE or just on one. What is the frequency of spots appearing? Less chance of happening if ASE is left in mint capsule ? Thanks.

I can't answer your milk spot question, but someone on this forum will surely have your answer.
We really need a permanent/sticky milkspotting FAQ
It has to do with the improper rinsing of the planchetts.....it's residue.

Hi,
All I can say is that none of my eagles have spotting. None of the ones I yanked from a brand new monster box have spotting. PCGS will not give a 70 grade to any UNC eagle even if it has no spotting, because it *may* spot later. So I believe the spotting is something that happens over time, eventually, but not in all cases. Since I live in the desert, I'm assuming it's a combination of humidity and something else that leads the spots to develop. Just my opinion, my humble opinion, in my opinion, no offense meant, with all due respect, IMO.
<< <i>Less chance of happening if ASE is left in mint capsule ? >>
I haven't seen a single reported incident of milkspotting happening to ASEs left in mint capsules on these boards yet. It's been reported to happen occasionally when ASEs are placed in TPGs slabs or ringed AirTites.
Not an ASE guy so I'll leave the answering to those that know.
<< <i>I think it is the unc"s. PCGS does currently give 70"s to proofs. Maybe good idea to stay away from unc til problem is corrected. Check out past threads on this topic. >>
Proofs also milkspot but not as often and not as badly as uncs. PCGS has been more successful in removing milkspots from proofs than uncs.

I've had milk spots appear on my proofs as well, but they aren't as bad as the ones on the unc eagles.

Interesting. I collect both Unc. and Proof ASEs. none of my proofs left in the mint capsule have milkspotting. The only Unc. mints I have in mint capsules are from 2006 so there's some time left to see if it develops. As for my Uncs purchased on the second market? I have an average of aobut 3 to 4 per year since 1986. All are in airtites and none have milkspots. That's 22 years worth, about 80 Unc. coins and no milkspots.
So this is a good question to post. I've always been curious why this is such a big issue and TPGs won't grade 'em MS70 because of milkspots. Go figure!

Is milkspotting expected to be an issue with the 2006-W ASE? They were struck on special "burnished" blanks.
If the production process for the 2006-W was different from the process used to make the bullion coins, there might be less chance of spotting.
If the production process was the same as the one used to make uncirculated commemorative silver dollars, then the likelihood of spotting should be similar for both coin types.
Someone mentioned that it's possible it can be fixed by PCGS, is this true?

<< <i>I am very glad to see posts by others that have many ASE's without milkspotting. I have posted several times before that my sets have no milkspots.. but have no idea why. I have read most, if not all, the threads on this phenomena.. but cannot yet say we have identified either a cause or a cure - indeed, many have said there is no cure. Cheers, RickO >>
Not many are talking about Morgan dollars from the 1800's spotting. Alot of people DO have a problem with ASE's spotting shortly after being slabbed. Give to reason there must be cause. If a leading conservation experts says a low humidity enviorment is good for coins, that's good enough for me.

I haven't read all the milkspotting threads. But I interpret from what you write that the phenomenon occurs only with slabbed ASEs. Is that right?

The general consensus that I have read is the spotting is caused by a number of factors. Acid rinse during manufacturing, humidity changes and even the gasket used in PCGS holders or ringed air-tites.
A couple of spotting threads.-

I store all of my ASE Uncs. in airtite holders and I put the holders in Airtite album pages. The pages have boards that accommodate 4 holdered coins per page. The boards then fit into a pliable clear plastic pocket. Each album has 6 pages. The album is stotred in a rigid cardboard sleeve.
I put my Unc. ASEs in airtites about 3 years ago. None of them are showing any signs of milkspot toning. But I am beginning to wonder how safe they are.

If you are using the DirectFit AirTites, you are probably safe, however milkspots have been reported to develop when stored in the "Ring Type" AirTites. What kind of AirTites are you using?

Definitely the ring-type. Two hard plastic shells with a black foam ring.
Originally I had them in saflips, but they started to tone, so I decided to upgrade to airtites. I never considered that "museum" quality archival material would be unsfae.
Edited to add a link to Air-tite's website: The materials used in the production of our holders and rings are totally inert and PVC free.

Indeed. One day we may all be talking about how ASE were plauged by milk spots. A travesty to the future collectors no one can find a solution or even a direct cause

Kind of morbid but this may actually make collecting ASEs more interesting a few decades from now. Without circulation to wear down many ASEs, this may do the job and make condition rarity more important even in common grades the way that classic coins are available in a wide variety of grades due to circulation.
