Spotty Accented Hair 1964 Kennedys

I posted about this a while back, when I had a spotted AH half come back from NCS with the spots still there...apparently milk spots are common on these (thanks, Russ!). Has anyone recently come up with a way to remove them? I have an opportunity to buy over 30 1964 sets with AH halves, for graysheet bid. I picked out the 4 sets with no spotting (plus one spotted one for experimentation purposes), and bought them today, but the rest are spotted to some degree. Can they be salvaged? I've tried acetone, ammonia, and EZ-Est (diluted), with no noticable results...

I have one with a single very large milk spot. Its kinda like cancer on a coin.

Kind of like tattoos, eh?

That, and a cure, will be worth a lot of money.... $50K alone from PCGS... Cheers, RickO
<< <i>The spot on my Accented Hair ias rather large. Its large enough that you can examine it under magnification. Upon close inspection the spots look like some sort of calcium type deposit that is adhered to the service of the coin. It has a "rough" texture to it and there is no way it can be romoved. I even tried to chip it off with a sharp dental tool with no success. It really is a part of the coin. >>
I think the general consensus is that it had to do with the way the Mint prepared the either the sheets or the planchets.
Very common on a '64 Kennedy, nearly unheard of on a '63 Franklin, and I've never heard of it on an earlier Franklin.
Whatever was done, the Mint was able to replicate it on the Silver Eagles over 20 years later and it continues today.
Some folks have had limited success with fresher Silver Eagles, but when it goes back to '64, well you can pretty much forget it.
Put a fork in it, it's done.

<< <i>Another thing that is important to note is that even if the coin is spot-free when pulled from the set, it may not remain that way. They can develop the spots as time goes on. However, that can be prevented with a quick dip to stabilize the surfaces.

I assume you have dipped all of yours in acetone to be safe?

When I first started submitting I didn't. Which is how I learned the hard way that they can grow spots later. Since I started doing so, none have later developed spots. BTW, I don't use acetone. It is useless for preventing milk spots.

Good advice...I've gotten in the habit of dipping proof silver from that era as soon as I remove it from the mint packaging. A lot of the time, the coins are a little hazy, and it gets them looking as they did the day they were made. I've been using Ez-Est, HEAVILY diluted with distilled water. So far, no adverse results, and I've never had one BB'd for cleaning. Will this keep the spots from developing?

What do you use and what mixture, how long etc...

Yep, that's the ticket. It's really not necessary to heavily dilute it, though. The real issue is how long you keep the coin exposed to it. Full strength is fine if you're only dipping for a couple seconds. Just make sure the ezest is fully neutralized afterwards.

I'm interested in this too.

Thanks, Russ. I guess I'm a little paranoid whenever I have to dip a coin...having the Ez-Est diluted makes me feel a little more in control!
<< <i>There are milkspotted Franklin proofs at least. i know at least back to 1958. >>
That's news to me.
I've seen '63 Franklins with spots, but only a very few.
Thanks. I guess I need to check my batch of top proof sets, that is one thing I do collect, from only '64 and back though.
You know, back when money was real.
