It's very possible, even most likely, that what you're seeing is nothing more than the result of a plating issue and/or Zincoln cancer.
Thanks I use the cherry picker guide book and Lincoln resource and doubleddie.com but still learning . I only collecting Lincoln cent do you have a different sites or book .to look at. I try not to ask a lot of questions.
No worries; ask away. As long as one is serious about learning and/or contributing, no one here will fault them for asking questions. Unfortunately, there are some folks who seem to think the membership is here for them and only them, and is why you may sometimes see a little blowback. The LCR and Wexler's (doubleddie.com) are both excellent sites that can teach you a lot, although the latter is more geared towards varieties than errors. The cherrypickers books are okay, but they're nowhere near the definitive references some make them out to be, and one can actually find the same info or better online for free. Still, and as with most everything in this hobby, take from it what you can and/or that benefits you; the more factual information you ingest, the better your experience will be. Here's a couple of other sites that may interest you.... http://www.error-ref.com/ http://varietyvista.com/CONECA Master Listings.htm If you get stuck or are unclear on anything, please don't hesitate to ask the board for clarification.
Simply put, zinc rot in the top photo and die deterioration doubling in the bottom photo. Not an error. You can also see the deterioration doubling along the edges of the Memorial. This is a late stage die that should have been taken out of production and retired.
I am new to all of this and still learning. This might seem like a silly question but I do not know how to differentiate a business strike from the other. (see, I can't even remember what it's called)
Proof. Proof is a method of manufacture and are made as collectibles. Business strikes are made to be used in commerce. I'm sure if you google and/or search past forum threads for "proof vs. business strike" you'll be able to learn quite a bit. Still, if left with or you have any other questions, feel free to ask.
Close, but not quite. As said above, the difference is in how the two types are manufactured. A proof coin can circulate as well, and in fact many have. The term circulated is used to describe a coin's condition as opposed to its history, and can be understandably confusing for those new to this hobby. Does this help?
