Please post your "toned" Coins, Tokens and Medals.     Toning occurs over long periods of time, as the coin’s metal is exposed to oxygen and sulfur. This process takes years to occur, with most natural examples requiring decades to fully develop. Environments where toning is most likely to occur are high in both humidity and sulfur. Typically, bank bags and paper envelopes are a catalyst for toning due to their high sulfur content. However, the simple truth is that toning can and will happen unless the coin is vacuum-sealed.   The colors that a toned coin displays depend on the composition of the coin. For instance, freshly struck copper has a bright red color, but over time oxidizes into a dark brown. On some rare occasions, copper coins may obtain a lustrous rainbow toning. Silver, on the other hand, is much more likely to showcase a stunning rainbow patina that ranges across the entire color spectrum.   Thanks, and stay warm everyone!
