It is too hard to take all of these at one time. We need to see the date/mint mark locations and the hub doubling one coin at a time. Too many things missing to tell for sure on them. For example the first one might be a
DDR, but it might not be listed. But to have an image of the date and mint mark position, it would be easier to see if it is listed or not. I check the Wexler listing and they are incomplete for this year. Just a few listed for this year on Variety Vista. (they usually only list the strongest varieties) Coppercoins list a few more of them, but again they are the stronger examples. Another factor to figure in is circulation damage to the coin. How much of the flattening was done to the coin we are looking at. So I prefer to do assessment on single coin posts. I prefer to educate rather than just give yes or no answers. Having just the answers doesn't help the collector learn. I like to put the information all out there to
show what I see on their coin. That way, the collector can learn, rather than just be told what the answer is. What if we went to school and were taught math by the teacher just checking to see if our answers were correct, but never taught how to
get the correct answer. Kind of like the saying: "Give a man a fish and he will eat for a day. Teach a man to fish and he will feed his family for a lifetime."
So I feel time is better spent on teaching, than on just giving the answers. So the best way to learn is do these one coin at a time. Also allow enough time for the subject to be considered. Probably many coin the OP will see what the answer to himself as he goes along.
That is real coin education. something that not just the OP will learn, but the others who read these answers will also benefit from.
