So I found this penny that looks bright orange and it got me thinking as to wether this is toning, what exactly is toning? and why is it diffrent from PMD exposure damage? Like too much sun or salty air by the sea. Or is this some sort of acid wash result? although I wouldn't think so, most every time I see a coin bee washed with anything it generally turns pink or pale yellow. In case you can't tell exaclty how far off the color is, because that color looks pretty normal. Here's another 2018 d side by side. And Finally, side by side.... Here's somre more shots of the orange coin...
Coins and metal in general can react to different chemical. Jewelers use them to color jewelry to make it different and appealing. Coins get it from what they come in contact with. Even storage materials.
What do you expect from a zinc Cent? The copper coating is extremely thin and copper is very reactive. It doesn't take much to change the color. Just a form of toning.
So, is toning a good thing or a bad thing for the value of a coin? ... Here's another pic with 3 diffrent tones in the same year.
Great question with superb illustrative photography AND spot-on, enlightening responses. If only all CT submissions and feedback were of this caliber! My thanks to Tin_Man_O et al.
It really depends on the toning, I can only ask you though do you think a 2018 cent has had enough time to tone naturally or do you think it was accelerated. Accelerated coins do not get a premium in the market. Not to mention the circular marks are damage.
