Removing Haze from Proof Clads?

FrattLaw

I have several Ikes I'd like to send in for grading, except they have almost imperceptible hazing in the fields. I can see it with my steroscope and know that once exposed to air it might accerlate while awaiting grading.

Has anyone found anything that can remove the haze without effecting the rest of the coin?

I have EZest and have tried dipping (silver) before, but as for clads, I'm still unsure.

I also have a blue proof 62 Jeff with very light PVC can PVC be removed without stripping the toning?

Thanks
Michael

IF theres not additional cost,have the service dip it before slabbing for you.

You might try MS70 Coin Brightener to get the PVC.
I think MS70 leaves the toning intact for the most part,but you might want to wait for more informed opinions
to come along.

MS70 is good for the hazy stuff but it's slimey & hard to wash off. I never had any luck dipping clad or nickels. It has something to do with the copper in the alloy and retones funky.

Ditto. No matter how careful I've been with clad proofs, they always seem to develop that telltale gold rim toning within a couple weeks. I don't even try them anymore. Silver and silver-clad never seem to be a problem.

ya ,it reminds me of a mixture of motor oil and dishwashing liquid.

VERY slimey,and hard to completely rinse off.
Maybe multiple dips in acetone and water,and in a couple months you may STILL see you DIDN`T seem to get it all.
A few red/brown spots mysteriosly pop up.Same with useing eZest,if not thoroughly neutralized with the water and or acetone.

I just performed my first dips the other day (including a clad commem) and posted a thread describing the process. Do a search for 'dipping' it should be the first result from only 2-3 days ago.

Thanks Al, I didn't even realize it was off.

BSqr,

How long has the clad commemorative been out and exposed to the air since you dipped it?

I dipped in 2-3 days ago. After dipping I let it sit out for maybe 2 hours then put it back in the capsule where it is now. SHould I expect some unsatisfactory results in the near future?

Yep, afraid so. Irregular brown spots coming your way.

Regarding MS70, per a board members suggestion (I forget who) I tried it again, and with rinsing it off with hot water to remove the MS70. Which worked better, but... the heat caused my entire proof to turn deep gold! So I dipped that, etc... and basically ruined a decent coin.

So, to date I also have never had very good results dipping clad proofs. The problem, I suspect, is that the outer "nickel" layer is in reality 75% copper, which is highly reactive.

FrattLaw, from your description, the haze sounds very minor. I'd send them in as-is, any further reaction upon exposure to air will likely pale in comparision to the reaction you'll get from a freshly dipped coin. Or if you don't think you'll be happy with them... leave them in the proof set and keep searchin'. Save yourself the hassle.

Also keep in mind once you crack that set open, you'll have to find some way to dispose of those worthless coins like the Kennedy.

I thought people liked Acetone, but haven't heard about it in this thread.

FrattLaw

As for those useless coins, I'm trying a little toning expertment. I don't know if you would call it AT, but I'm trying to see if I get some nice color on the the others.

I'm keeping the other coins in paper 2x2 envelopes, storing them in a paper 2x2 box and keeping them under my kitchen sink, where it should be humid and full of gaseous chemicals. God knows what cleaning products my wife keeps under there.

It may be useless, but its still fun trying.

Would that still be AT if it took several years for anything to happen?

i've had success dipping proof jefferson's and clad mint state ike's, essentially the same thing----25% nickel and 75% copper. no brown spots on either after about two months. while i haven't dipped any clad ike proofs yet to remove haze i expect the same results as the nickels since they are the same composition. and the haze dissappears.

I never rinse with water, copper hates it. coin goes straight into acetone bath for a long soak after dipping (and usually before a dip too.) no spots, no toning and stable long-term. I'll go to the art supply store for a bottle of liver of sulphur if I want wild toning

Acetone is the best for removing PVC or hardened ink and stuff like that. Has no effect on a coin's surface so it is safe for every metallic coin. (plastic ones, though... )

coppercoins

Actually, acetone will screw up and cloud the surface of proof coins. Why, I don't know, but I've ruined a few that way. It does the same thing it will do to glass microscope lenses (ouch!).
