Does NCS conserve proof coins? or is.....

.....there a way to clean spots of of them before sending in for grading?

What happens when you do a quick dip on a proof coin?

Yes. NCS conserves proof coins.

I've de-hazed some proof coins successfully with an acetone bath, but it doesn't always work.

Yes, NCS conserves proof coins. Whether or not spots can be removed will depend on the nature of the spots. The mint-caused milk spotting that was fairly common on early '60's proofs is embedded in the planchet and is not removable without damage. Light water spotting or other minor spotting caused by post-mint contamination can usually be conserved.

Has dipping ever been known to hurt the frost? Or even impair the mirrors?

It will not hurt the frost, but over-dipping can hurt the mirrors.

Thanks for the input. I'll have to take a close look at the coins and determine if ther worth sending to NCS. I might find a couple beat up proofs with spotting and dry a quick dip to see the effect.

Thanks again,
Randy

disagree w/ russ. if you dip a frosted coin enough, the frost will be inhibited.

it is correct the mirrors will be damaged by overdipping too.

may be pertinent to someone's recent question about curating proof-like coins.

I sent one dcam proof dime variety to NCS for conservation. It had several spots on the obverse and a bit of haze. They did an absolutely wonderful job and only charged about $15 if I remember right. They did such a nice job, I sent them some more valuable pieces to work on - it will be interesting to see how they do on those.

If your proof coins just have a bit of haze, I have been successful with a 25% solution of MS70 with careful application with a cotton swab, lots of rinse water, and blotting dry. This has been covered before in previous threads.

I avoid dipping at almost all costs - more of a last resort for me. The others are right, the mirrors will be affected by overdipping which will likely cost you a shot at dcam status.
