Found this 1958 D Franklin in a coin roll. Not sure what causes this light "gold" coloration. Would it be considered some type of toning and does the color alone affect the value in any way?
It's not uncommon for silver coins to tone. Don't try to clean it. The toning will not affect the value in a bad way, it may help the value a little bit.
Actually toning helps sell coins whether or not it looks nice or not. Some are beautiful, some are bow wows. I am always amazed how toning causes bidders to bid up on an otherwise "meh" coin on Ebay. (not that the coin depicted is not nice, it's a real beauty).
ROFL - obviously you have never read the coin preservation handbook! Your not aware coinage metals react to the atmosphere, heat, humidity? Wow you really don’t know much do you.
Not the air itself but what is carried through the air. We can’t see germs but we get sick from breathing it. The air carries minute particles and coin, being different metals, react to what’s in the air. This is coin is toned, very nicely I might add.
Leave some silver dollars in a hot humid garage for a couple of years - they will turn black. Especially a beach town lol.
I think Green is most likely unless you have yellow-orange lined paper. The paper in the last photos were closer to the normal white of writing paper and the coin sides were close to being normal. The rest is just chemistry and the coloration is related to the chemical reactions, concentration and time. It almost always can be prevented with knowledge and attention.
