Some Of The Lincoln's I Found Today.

The reverse of the shield cent looks interesting. Can you get more pictures of it?

The others look like worn dies or Machine Doubling but it is hard to tell with the photos. Do you know to look at the reverse of the 1992-D for the Close AM in AMERICA? http://www.coinworld.com/Articles/V...lizes-20-700

There are many other design varieties from different years to look for also. Check out Copper Coins website for ideas on what to look for with double dies and RPMs.

To me it looks like almost all of them are Die Deterioration Doubling. Its hard to get good feed back on a thread when there are more than one coin to examine. If I were you I would look up Die Deterioration Doubling, Machine Doubling, and Doubled Dies. Then post one coin in a new topic that you still have doubts about. (I think there is a sticky post on the very top of this forum that gives you some guidelines posting your thread that will get you the best replies.

The reverse of the shield cent looks like the most promising coin you have posted IMO.
