Does Toning Of A Slabbed Coin Affect Price?

I 2nd what Denco said. As an example, I would much rather have my example (below) than a blast-white example. The attractive toning adds some character to a coin.

Thanks everyone for the replies. I prefer the all white ones myself, but I also understand it's a matter of personal preference.

My primary concern is if I buy that all white shiny specimen today, store it properly, and in 20 years it still discolors in the capsule, do I still have an MS-65 graded coin?

Those are truly beautiful examples. Thanks for posting the link.

The unknown is kind of making me nervous that if my investment tones poorly even in the sealed case, it could detract from the beauty and value of my investment. I don't know. I'm new to this, so maybe I'm just being a bit overly concerned. Or maybe I don't have the stomach for numismatics and should just stick to bullion. While I know there's still risk in what an ounce of gold might be worth in 20 years, at least I'll know it will still be an ounce of gold. :)

Coins often do tone inside slabs, either because reactive substances are packaged inside the slab with the coins, or because chemical vapors and moisture penetrate the slab plastic. The paper inserts, the interior surfaces of the slab plastic, or the surfaces of the coin itself are potential sources of reactive substances. You can't do anything about these unless you want to crack out the coin. You can control exterior threats by keeping the slab inside an inert environment. Use desiccant like silica gel packs inside your safe, safe deposit box, or other enclosure where coins are stored. Obviously, make sure your coins are kept away from sources of vapors such as fireplaces, cigarette smoke, drying paint, etc.

ICG used to supply storage boxed lined with a product called "intercept shield" that absorbed chemical vapors and theoretically protected the coins. This material could also be ordered as an insert for their slabs. Here's a Barber quarter packaged inside an ICG intercept shield slab:

All toning on coins is some form of environmental damage.
I prefer blast white with perfect lustre over a toned coin any day.
Having said that I DO enjoy toned coins as long as they look good, the dark black on silver coins is a definite turn off to me.
Each to their own but they never left the mint in a toned condition.
The toning CAN hide things in the lustre of a coin and in my opinion should be discounted against a coin of the same grade without the environmental damage.
This is just my own opinion and the way I like to collect.

I think the toning absolutely does affect price and can even affect the grade given.

Thank you all for jumping in and posting. It's nice to get so many people willing to help and share their thoughts and opinions so quickly, and I appreciate every single post.

I especially like chesterb's idea of snapping a photo today and checking in a year or two. If I do notice changes I'm not particularly comfortable with, I could always unload it at that time to alleviate my fears.

Thanks again everyone! :)
