Found it interesting what this seller does to "restore" his nickels:

I think I have a 1914-D somewhere about in my coin miscellaneous box. It is all corroded. Probably will not acid-treat it, but is there any numi worth to a readable date, corroded 1914-D nickel?

I don't see how he has a problem with the term "chemically altered."
But to answer your question... yes., I believe this will retain at least some numismatic value because it is a "key."

If you can read the date and mm don't acid treat it, you'll lower the value whether if its corroded or not.

Is anybody going to take him up on the offer to 'buy him out' for one year for $25,000?

Would nic-a-date be what he is using

The one container is the same thing as nic-a-date, it can be bought at radio shack.
His nice little secret is gonna cost though.

I've seen some of these "restored" key dates sell for about 10-15% of book value in the past.

I have a 14d that I soaked in vinegar to get the date to show. It was a dateless but the vinegar allowed the date to "reappear" after soaking for about 24 hrs. You can tell it has been "treated" but for now, it fills a slot in my folder.

Good example. It may sell for 10% of book, but it's worth more than it was... dateless stuff is everywhere, and can be had for just a few times face! Good success story agmoose!

I got a sample from him. You can tell they have been cleaned. There are abrasions going all across the coin on each side.

This does not sound like a bad idea. Dateless coins are pretty cheap. I imagine if you bought all the dateless buffalo's you find with mint marks, you are bound to find a few key dates and make a bit of money. Not worth paying for his secret though.
