So am i only supposed to base it on what a record says or is there a way to be able to identify from simply looking at it weather theres a doubling going on. I mean what qualifies a doubling to me the details are on the surface by looking at it shouldnt we b able to tell? Like finding a new error what makes that qualified as an error? Thats how good i want to get any advice on that? because im looking at this and im not seeing any scrapes on the eye just a pressing that could have be done once over or so i think based on the shape it has, this is why i mention it here what am I missing. Maybe you can answer that. Please dont tell me experience tell me what experience tell you... Should i look for any dis-qualifiers. Like on the surfaces that say Nope not an error. Feedback on this will be greatly appreciated. Thank you for all your responses. I am really wanting to get good at this, again thanks!
There are a number of types of doubling on coins. Machine Doubling, Die Deterioration Doubling are the two most popular. Do some research on Doubled dies, like the 1955 obverse Doubled Die Cent and compare that Doubling to MD and DDD. A true Doubled Die will be worth more. All other forms of doubling are NAV or No Added Value Doubling.
The first time I came across one, I thought it was pretty special. After coming across quite a few of them in a very short period of time and learning about what it actually was from those on this site, I come to understand it's nothing really that special at all and quite a frequent occurrence with coins, especially with zinc pennies.
It's a shame isn't it? I love looking at a nice copper Lincoln, Memorial or a Wheat as they have style and class. These Zinc Cents rot while you hold them.
