Toning is caused by exposure to hydrogen sulfide (H2S). The sulfur reacts with the metal surface to form the corresponding metal + sulfur. Light refracts differently based on the thickness of the layer. It's kind of like how light + water droplets form a rainbow. The book Coin Chemistry details H2S and its role in toning very well, it's worth a read.
Thanks a LOT for this information, BadThad! I've been wanting to know the chemical process that creates a toned coin. I will definitely check out this book.
I'm jealous of everyone's toned coins. They are all so pretty!

maaaaaaaaaan there is some nice stuff coming out here!!  I picked up a 1964 Mexican Peso at a coin store in El Paso this week. I believe it's 10% silver and it BU with some toning on it. The guy only wanted $2 for it, so I said SOLD. Of course, I'm sure he would rather I had purchased the slabbed 1916-D Merc or 1893-S Morgan he had. If you guys like toned coins, check out http://www.islandcoins.com (I have no affiliation to this site). I'm contemplating buying something from there. Has anyone dealt with them before?

I've never heard of them, but they seem to carry a lot of really nice coins, I especially like their wheat cents and morgans. They also seem to sell on eBay, their seller ID is islandcoins.

Is the Buffalo slabbed?Wheatman, it's currently entombed in a PCGS ms65 slab. Has anyone dealt with them (Island Coins) before?Gothic Florin, I have dealt with Gary (Island Coins) on several occasions (both buying and selling), and can honestly say he is one of the good guys. Two thumbs up!

Here's one of my Indians. There really is some nice toning that isn't in the picture, and it looks like there's toning on the rim. Those are some really amazing coins, Nelrak and Hadleydog. I especially like the proof indian and that SLQ. That FRanklins really nice too, Dcrews.

The BTW commemorative was glued to a cardboard holder, the white area is where the glue was(removed with acetone) and the toned area was directly touching the cardboard.

I question the toning on the last two Morgans but I am pretty sure everything else is naturalThe 81 and 98 are most likely at'd, the colors and progressions are not right. That '21 Morgan of yours is a moose for the date. Sweet!

I'm just gonna head off the NT vs AT argument. Lets not care HOW it got toned...just that it IS toned and beautiful.
