Weird, probably stupid question.
Even slabbed, highly graded coins, some are toned, some not at all. Strange.

In terms of the overall question unfortunately the answer is in a lot of cases just because. There obviously is a reason but no one to date regardless of what they say has proven to be able to tell if a coin will ever tone or take color or not. You can literally put a roll of spread out coins in a spot and get all different results. If someone has a bunch of ASEs or new mint coins play around it with it or put a few here and there and see what happens. For some reason some coins seem to tone fast, some not at all, and the rest gradually over time Quote:

Good luck trying to figure it out. I heard that outer rainbow rim toning can be accomplished on a silver dollar by using a tissue while being placed in a smaller half dollar holder. Two years later and nothing significant happened on that particular coin.

The answer is really simple. Coins that don't tone are made of materials found at area 51. Our government found large quantities of materials from alien space ship crashes so they made many coins from that stuff and they just don't tone. Other coins made from materials from Earth tone. Also, aliens shoot toning rays at Earth all the time and if your coins have been in a location where those rays can get to them, they will tone. I advise all to contact your government and suggest a ban on those rays now.   |

Neither weird or stupid. I've wondered that very thing. Especially with the Prestige Proof sets of the eighties and nineties where just the dollars sometimes seem milky. Most peculiar indeed. For that, I'd say it was more than environmental.

Excellent question, and a very difficult one to answer as there are just so many variables.
The actual metal content is one variable.
Planchet preparation, including the rinse, is another.
Storage conditions (damp, hot bank vaults from 100 years ago).
The actual bags they were stored in, including the fact that the bags from over 100 years ago were sprayed with a sulfur solution to keep the rats away.
Time stored in these conditions (read more than 60 years in the case of Morgans).
Placement of the coins in storage (up against the bag, most likely toned. Middle of the bag, just a nice thick skin).
Dumb luck.
