Rainbow Toning On ASE Coins

You probably would be better off posting a few pictures of your toned coins so people here can get a better idea of the type and amount of toning you are talking about. That way you can get a more precise answer.

First, to a fellow ASE collector!

And with both sel and Rothery:

Some folks will ask for insane money for outlandish toning on ASEs (check ebay) but you are better off putting your money elsewhere.

If/since your ASEs are beginning to tone, check your storage. If you live in a high-humidity climate, you'll need to make sure you're conditioning (i.e., drying out) your storage. That is the primary culprit when ASEs tone.

Good luck and we'd love to see some photos.

First of all, thank you for all your comments, advice, and suggestions. However, what I am wanting to know is "Will the natural occurring (not artificially created) Rainbow Toning developing on the obverse/reverse outer 1/8" side edges of my American Silver Eagle ( ASE) coins eventually corrode, destroy, and "eat away" the minted coin's surface where the toning is located? Presently, my ASE coins are stored in a DANSCO album that is at least 23 years old; however, was new when purchased. Since I live 15 miles east of Dallas, Texas, my residence is not located in a humid region and the DANSCO album is stored inside my home in a 5 drawer wooden cabinet with a small pillow on top of the album. I do not like the natural RAINBOW TONING my ASE coin's are developing since I prefer the bright "cart-wheel" frosty swirling luster appearance when the coins were first purchased. My next question is "If the natural occurring toning does eventually destroy the coin's surface, wouldn't it be better to attempt to remove the toning by "dipping" (not rubbing) the coin in a mild silver cleaning solution (please recommend one) to preserve the coin? I realize these are silver bullion coins; however, all of my ASE coins would grade at least MS69 since they are visually perfect requiring a loop to identify any imperfections. Lastly, when the BU ASE coins are quickly dipped and rinsed with distilled water, will the BU coin's "cart-wheel" luster be lost and the coin's background frosty appearance changed in anyway? I will be looking forward to your responses. Once again, thank you in advance for your comments, advice, and any suggestions you might have.

Ok, some rim toning. I don't think in your lifetime you will see that take over the coin, turn black, and start ruining the surface. I heard of it happening but have never actually seen it. I have seen the colorful toning turn to black and that is pretty unsightly, but then again, not to worry as that takes many years. As far as dipping goes to remove it - I've never dipped a coin so someone else can help you there.

For any silver dollar sized coin in MS blast white condition and appearance,
I would enclose them in individual snap shut air tight acrylic capsules.
You will then not have to worry about a humid environment.
If you wish, put the capsules in 2.5x2.5 inch 12 pocket non PVC album pages, and seal the pocket openings with tape.

If you are still worrying about the humid conditions, put the album in a clip lock plastic bag of appropriate size.

Light toning will not affect the value of a bullion coin; it's just that as the toning increases to affect the eye appeal in an unsightly way, some coin dealers will offer a slight discount price under that for an untoned coin.
As seen here in the CCF, lots of collectors appreciate nicely rainbow toned silver coins. Those coins with blotchy toning are much less appreciated, - that's a collector issue, not a bullion problem.

Although toning can be very attractive, it is nevertheless an extremely mild form of corrosion, but it should never affect the actual silver value.

As far as I am able to discern, specialist bullion dealers will still happily buy back lightly dipped silver bullion coins.
