I find it interesting that there is no "toning" where the fingerprint is. Could that be where they held it as they "toned" it?

Add that to the added toning, and I would say bad coin.

The post just happened to be during a quick break I was taking from work. I've only been able to check out the forum about 4 times in the last two days. Busy, busy, busy  |

I thought that also but wasn't sure if something on the persons finger could "wipe away" the toning. Is that possible? |

Acetone or other cleaners will wipe toning away. However, this was done while the toning had not set in yet. My immediate guess would be baked toning.

Ok, baked toning, I take it is when the coin is put into the oven or some other heat source. So how could they get a fingerprint on the coin while it is hot?

It would not have to be hot, just not set yet. Take a coin and set it on a lamp. The coin will tone pretty quickly. If you touch it before it completely cools down the toning will smear or leave fingerprints. Suffer works the same way, however doesn't settle well on silver coins.

If I wanted to run a toning "experiment" besides a heat source, sulfer, other chemicals and some coins, what else do I need and how much time will it take?

You ought to see some silver eagles I used to have...I got them when I was younger and didn't know a thing about coins so you can guess how I held them....last year I sold them...made $2/coin off of them but man were they covered.

I have been working on this very thing for better than a month. Some chemicals take longer to cause toning than others. The ones that take the longest are often the hardest to spot. Which is exactly why I embarked on this. So here goes the list:
Rubber gloves. Some chemicals are not healthy.
Seperate containers. DO NOT mix chemicals.
Other than that, I would suggest trying anything you can find. One neat thing is laundry detergent. Let a nickel soak in it for about a month, then slowly cook it in the oven at 350 degrees for about an hour. I use ALL detergent. Now before anyone asks why soak for such a long period of time, it builds up on the surface. Now, make sure that the coin is very cool before touching. If you burn yourself, don't come back here complaining to me. If you wrap it in tinfoil first, it turns a really beautiful blue.

You mention a nickel, will other clad coins work or should I stick with silver ones?

Or you could leave your whole collection in non-temperature-controlled environment like an attic or a garage  |

All coins react to their environment. Paper and cardboard is effective but take so much longer. Put any coin in a manilla envelope and place it in direct sunlight. The toning is pretty quick, (about a week) and is hard to detect.
