Now i am still extremely new to coins, and don't even have a toned one yet as ive been sticking to proof sets, and rolls until i learn more about collecting...but the few sites i have seen suggest that toning is the chemical reaction...and mostly to sulfur...now if that is the case, why are so many people interested in encapsulating their coins...why not move to some areas in PA and NY that smell like rotten eggs all the time and leave your coins out to soak it all up... please feel free to flame the new guy...
Hey we don't smell like rotten eggs ALL the time, just most of the time LOL. Encapsulating the coins is just a way of protecting them, because some people personally don't want their coins to tone, and also you never know how your coin is going to tone (not all toning looks nice). BTW Welcome to the forum.
Welcome to the forum. I agree not all toning is attractive. If you are buying proof sets more than likely you will have some toning on some of the coins. The farther back you go the more likely. The kind of toning you like is a personal preference.
Not all people like toned coins. There are plenty of collectors who prefer them to look brilliant, like the day they were minted. Some people consider toning to be damage to the coin.
