Soo..I'm sure the answer to is this a doubled die coin is no, its only machine doubling... because I'm usually wrong when I think it's real doubling lol...but thought I'd try again and also use this post at at the very least as an opportunity to share this beautiful (in my opinion) toned penny I found
Looks like a plating issue? But I'm not an expert so wait for one to come along. Also, about the toning. I am not sure. But there is some toning that suggests coins have been in contact with urine and other types of substances. Not sure about your coin. Again, the experts can look and almost know in an instant. I hope your coin has "good" toning and not the yucky icky kind.
Hi Charlie, Imho,it looks like md with some die deterioration. Not sure on the platting issue but I like the Toning!
I am not sure what caused the color, But deep purples and red brown is a natural color for aged copper. As for anything else you are seeing. It shows many different types of worthless doubling. Have you read through this site? http://doubleddie.com/144801.html Even if you have it is worth reading over and over until it gets instilled into your brain. DDO's and DDR's are valuable because they are rare, and you shouldn't expect to find one unless you know what you are looking at. Here are the different classes of Doubled Dies. http://doubleddie.com/58222.html
Thank you, I have but will read again... Just when I think i get it I don't lol....I did think most of the stuff on this penny was machine doubling, except the D mint mark & maybe his hair ...but then I doubt myself... & The D threw me off for sure
Worthless doubling. If you see the same type of doubling on the same denomination and different dates then it's worthless doubling. As for the toning it looks natural but it's also on a zlincoln.
A cent made of Zinc. In 1982 cents were made from copper then switched to zinc with a thin copper coating. It was a transitional year. All Cents since then a zinc. Zinc is a terrible metal to use as it causes numerous problems. We cdll them zlincolns.
Nothing but you get some strainge results. They're newer coins so toning is not normal. They have an extremely thin copper coating and copper is highly reactive to the elements. The thin copper coating reacts faster than a solid copper coin but you get weird looking Cents.
Not bad but I'd put in an airtight to reduce future toning. An airtight would be better than a 2x2 flip.
Toning is storage related. There are a lot of good threads on this topic here on CT. Proper storage conditions will reduce the amount of toning a coin gets but all coins will tone over time. You want a cool dry place with low humidity to start. Also air tites and intercept shield albums tend to be the best.
