Like can you purposely tone them?

Google or search these forums for "artificial toning" (AT). Coins tone naturally (and unnaturally) by coming into contact with sulfides, mainly from paper products. I recommend searching this topic because any one of us here that's familiar with toning could write an entire book about the subject - regarding both the good/bad and intentional/natural aspects of it.

 

Omg.

 

probably just a newbie thing

 

Artificial toning isn't a good thing to get into...

 

Humidity.. Moved from The Nevada Desert to the Oregon Coast (Employment) in 2000. My Silver Eagles have developed a copper toning along the edges moving towards the center of each coin, despite being in Dansco Album. Same for my Mint State Franklins despite being in a Littleton Album. The Toning is attractive but I am amazed in just 10 years this could happen!

So... some toning types/colors decrease the value of some coins while increasing the value of others?

 

Welcome to the Forum Steve. Now according to many on the forum, if you moved on purpose to get toned coins, you are a coin doctor and the coins are AT. If it was unintentional, then it is OK, they are NT. That is why there is so much confuscation.

We are talking about a group of chemical reactions that can go through a process of reacting with a coin and if uninterrupted can go from no toning -> toning spectrum of attractive ( to some) --> toning spectrum of unattractive colors ( to most)--> damaging corrosion. So mostly increases occur with the early stages, and decrease starting with the unattractive. My opinion.

Hydrogen sulfide is a common occurrence that can tone a silver coin into beautiful hues. I once went hunting with three other guys, before we pitched camp, we stopped off at a local diner and had the Blue Plate Special, corned beef & cabbage…by that morning all the change in our pockets was heavily toned.

 

Ya bid goof! LOL So if I keep my coins in the bathroom would that be AT?

 

I'd like to get my Morgans toned like rainbowish what should I do?

 

ENJOY Them! Especially the Rainbow ones! They are becoming very popular. Black toning, not so much!

It is stunning to me, I thought the Dancso, Littleton, even Whitman Coin Albums would make them inert. They did not tone in the desert!

Thank You, Jim. You can chalk me up as an NT Guy!

This is the primary reason the Air Force chose Tucson, Arizona, Davis-Monthan AFB to cocoon all the unused and aging aircraft. Due to the desert conditions, low humidity, low rain fall, metals have a tendency to resist corrosion. The best place to store your coins would be on our moon.
