Toning occurs naturally over time. It is primarily the result of oxygen and/or sulfur reacting with the coin's metal. However, the toning process can be accelerated by heat, moisture, and various chemicals in the environment. Some of the most harmful chemicals to coins can be found in cheap coin holders and coin folders.

Silver coins tend to tone in the most vivid colors. Colors can range in various hues from brilliant blue to deep magenta, from vivid red to deep orange, and a variety of shades of olive, green, and gold. Additionally, toning can also turn ugly and occur in shades of black and brown. In the most severe cases, the toning can turn into corrosion and cause permanent damage to the coin's surface. In the worst cases, corrosion can render the surface of the coin porous such that it looks like it was sandblasted.

Naturally toned coins are the result of a long and slow process in which chemicals in the environment affect the surface of the coin. Morgan dollars are one of the most popular series of United States coins to collect with vivid toned colors. Naturally toned coins can bring a premium several times more than an untoned coin...

Some coin collectors will pay a premium for toned cons with eye-appeal, but other consider toning to be damage.

Coin Toning Definition, Discussion and Effect on Value

Eye appeal has become a very important element for pricing rare coins, and toning is just one of the many important factors that must be considered. It is actually quite refreshing to see coins that sell more as pieces of art, rather than in relation to a Greysheet bid or retail price guide.

One final piece of advice: Buy certified coins to ensure they have not been artificially toned or enhanced. Recent auction prices have already spurred deceptive individuals to create pieces with rainbow toning to cash in on the craze for beautifully toned coins...

Jeff Garrett: Toned Coins - A Matter of Taste

When it comes to silver beach coins, they are different from most other collectible coins.  

Treasure coins are not always viewed the same way.  Many buyers of treasure coins prefer them to be shined up some and some auction houses will even suggest that kind of "toning" for some of those coins.  Of course, valuable collectible coins in high grades are viewed differently, and it is often said, by the collecting community that you should never clean your coins

Here is another old coin find.  This one has an unusual coloring.  Some coin collectors like the coloring while others view it as damage.

It was in a flip holder for some time and one day I notice the toning.  I think som coin holders didn't have the good archival mylar.

Can you identify the coin?

This one is a standing liberty quarter, but with a heavy patina and a lot of wear.  Some collectors consider the coloring to be damage, while others like the patina.  In either case, it is very heavily worn and would grade well no matter if it was or was not "toned."
