Here is one that is a common date that I picked up from by local shop and sent to NGC. I just got it back from CAC and Justin Lee who look photos of it. I also picked up a couple more just like it at the same time I think the one came from the same mint set but I've kept them raw and they are in my Dansco.
I found the spiked die crack over the eagle's left shoulder interesting on this 1959-d from a roll I purchased from an estate auction.
That's such a cool coin Physics. I like how the polish lines are imaged and freaking everywhere, like on a Type B. So sweet.
The area behind and in front of his head is die wear though. He looks all stressed out! Cool piece Physics.
