45 Yr. Old Commem BU And PL Type Set

First of all, to CCF!

Sorry rickyc, if the spots aren't easily blown off with a puff of compressed air, they are likely permanently part of the coin. That's the nature of silver (tarnish) and removing the tarnish will also remove any patina and thus render your coins cleaned/impaired. Sorry...

It would help if you could post pictures of these coins & their spots with which we could make a more informed opinion.

There are several ways to remove toning spots on silver coins.

The NCS Conservation Service of NGC is certainly one that can be trusted to properly handle and conserve your coins.

A few years back, I sent them a few of my Cuba coins that I believed would benefit from conservation. They were successful in eliminating the issues on all but one of the coins. For that one coin, they left it "as is" in its TPG holder and included a note that stated they felt the coin's surfaces would be damaged if they tried to remove the impairments. Ever since, I have recommended their services (when appropriate).

If possible, please post a few representative images of your coins so that we can see the extent of the spotting. There are quite a few knowledgeable folks here on CCF and we might be able to suggest potential alternatives.

One more question. Assuming the "corrosion(?)" has damaged the coin, what do I do with them? Throw them away? Get them worked on and they will be a much lower grade? Do people buy damaged coins to fill out collections?

Thanks - Rick

Oh, rickyc, where are your photos?!
