if you take a torch and hold it away from the penny the coin will do that. i rember as a teen we melted a coper penny over a whole in a copper pipe . ( my dad was nailing in the wall and hit a copper pipe in the bathroom) the pipe was running side ways the nail had grazed the top of the pipe making a big leak. we shut off the water my dad laid a old penny on it used a butane torch we had from a camping grill and melted it to the pipe it looked all funny , red ,green, bluish as it slowly melted around the pipe. It cooled off then my dad melted it agian and it just became a blob

That last one is pretty wild looking.
I'm sure the true answer is experience, but is there a tell-tale sign to look for that would set off bells and whistles to identify these if we were looking at one.

I guess there's a few things I look for....I'll try to describe them. - Unusual patterns. Toning usually tends to happen only on the fields, high points and along the rim (bulls-eye toning). AT just doesn't look right, it's just spread all over the place. - Mexican fiesta of colors, color progression. Coins usually tone in a defined progression of color, not "swatches" of different colors. The book coin chemistry covers the progression for silver nicely....great book. - Experience. LOL

Artificial toning always looks something like oil on water diffraction patterns to me. Lots of pretty colors bumped up against each other with no real progression from one to the next.

Quote: to me Fair enough. LOL Which I guess raises the question, for the most part we know what conditions cause natural toning. Is it considered AT if you create these conditions but allow the toning over a year or so? Is it to say that AT is toning you try to create and NT (Natural Toning) is unknowingly by accident. Just a thought. Personally I still dont like toning for the most part.

i think that if you natural tone it on purpose its still NT, I'm in the process of toning 2 Morgan dollars and a Bu silver quarter by leaving them out on my window sill.

So, is it considered natural or artificial if you place coins in a closed container where the air is sulfur-rich? I've always considered anything done on purpose to be artificial. I'll even go one further, if you know, or should know, that what you're doing will create toning - then it's artificial. Now, we've all seen beautiful target toning caused from being placed in holders decades ago. That toning I consider natural - at the time, no one knew (except perhaps a few chemists) what would happen - so it was unintentional. Just my Two Cents anyway.

I just picked up a 1969 proof set about 20 minutes ago, and the cent is beautifully toned. I consider that natural.

When people buy toners, they may never know. NT is NT, regardless of it was sped up a little. Nice Lincolns Thad, nice AT eye candy.

The old NT vs AT debate has been heavy for years. IMO, the terminology needs to be dumped. It should be replaced by "market acceptable toning" and "market unacceptable toning". I believe ALL toning is artificial since it wasn't created by the mint and it effects the coin.
