ASE proof with milk spots?

jrscoin · July 24, 2007 10:18AM

I got out my 2006 ASE sets yesterday to look and see if I had any MS69's worth upgrading.
I was disappointed in seeing several of the unc coins with milk spots however my PR70 had spots on it as well.
I dont have alot of experience with these but I have not seen or heard of a proof with spots.

Are these the same spots that affect the unc coins? Also would PCGS do anything for me since this coin is no longer a PR70?

Thanks

Welcome to the world of milk spotted SAE's. PCGS just started giving deserving SAE's the MS-70 designation but did not for a long time due to milk spots. I don't know of any way to get rid of the milk spots and neither do any of our fellow/fella forumites that I have read. Send it back to PCGS for regrade and collect the check...............Rick

With all the milk spots out there, I am surprised not to read a dissertation on all cleaning methods tried, a chemical or atomic absorption test of the spot, and at least some acknowledgment from the US Mint regarding the problem. Has anyone access to an AA or spectrographic analysis machine? Cheers, RickO

That's why I got rid of my sets before it happened,

Smart move

I do have access to a spectrograph. However, I can assure you that once it is on for the "burn", any and all of the residue will be gone with a 1/4" mark left from the micro sparking the machine uses to analyze the chemical make up. The material in the spot will be vaporized in microseconds and registered in with the miniscule amount of sulphur, phosphorous, etc. that may not even register at all anyway due to the purity of the silver.

It probably wouldn't be that hard to do a surface analysis at any reputable testing lab. The cost would probably be a couple or 4 thousand bucks. If we know the typical make up of the milk spots, one would be able to probably rid them through chemical reaction - much like putting an old Morgan in a bath of baking soda or salt solution on top of aluminum foil. The sulphur is attracted to the aluminum and off the silver coin through an electrolysis type reaction. The silver coins never look the best after this and are pretty dull. Research would then be needed to determine the best "pieces of th puzzle to use to mantain a "mint looking coin" in the end.

Perhaps the ship wreck guys have already perfected this?

And yes, I would love to find a cure too.

Yeah....I sold my son's set for him as well

Kept 2+ raw sets but sold the PCGS MS69 set and we bought him some other coins for the collection with it. I really didn't want to sell it but I was worried about the milk spots.

Yeah you can do a search on this forum for milk spots and find a lot of results... but please, prepare yourself for the horror!

I visited the SDB at the bank the other day and while there took the time to review the slabs.

I have 4 sets of (silver) Anniversary First Strikes left. I found no milk spots on any of the MS or Rev Proof coins. However, one of the regular proofs definately had one milk spot; it was a pretty small spot but you can't miss it on the field of the proof. I was bummed to find it.

If you haven't looked at yours in a while, I'd suggest looking.

I guess back to PCGS this goes to recoup a little of the loss.
Thanks for the replys.

Me too; esp the money reverse proof coin. I had one in PR70. Looked at my grandmunchkin's PCGS slabbed set a couple days ago. Still lookin good.

i wonder if we would have any better luck if the coins were made of stainless?

BAJJERFAN · July 25, 2007 3:54AM

304 or 316?

puritan9 · July 25, 2007 10:01AM

I only kept one raw set

An easy way to get rid of milk spots is to MELT the ASE

jabba · July 25, 2007 11:08AM

How did you store the coins?

leoprdfrog · July 25, 2007 11:14AM

With the whole milk spotting problem do you think it could in the long term future lead to us seeing a premium for non milk spoted ASE? even non key dates?

ASE proof with milk spots?
