I'm not an expert at this .. but I think you are just seeing the remants of metal flow around the dates or early stage of die deteriotion (moving towards Mechanical Doubling ?) especially with Zincolns. But not Doubled Die @paddyman98 @furryfrog02 did you see a youtube video about a super duper rare 1983 D cent in your pocket change ?
Thank y'all. I didn' know what I was looking at. It kind of looked doubled and didn't. I needed y'alls help to tell me.
It's tough, but I promise that one day it'll just click. If you haven't yet done so, check out the below links. They should be both very helpful and enlightening as well. "Worthless doubling"... http://doubleddie.com/144801.html "Doubled dies"... http://doubleddie.com/58222.html "How dies are made".... http://doubleddie.com/58201.html Good luck!
If you think about it as "metal flowing" and that flowing metal interaction with the die, then you can think about the process of aging (aka deterioration of the dies). With a new die a coin will have a nice sharp, clear design as time moves on the constant strike of metal against metal will wear down that harden die and you start getting wear sharp edges worn off or slight breaks or "die chips" and "cuds". Then you get as above "die deterioration doubling" then you get more "mechanical doubling" I think that's right ... at least that's what makes sense to me right now. and Double Die is totally different, though some of the variations can be confused. It's a constant evolution of learning ...
