I need more eyes on this one. It looks like it could be a DDR but could also be deterioration die. What I question is the lines at the neck (marked with the yellow arrows) and also the ?lamination peel? on the bust at the bottom. Looking at coppercoins....I couldn't find anything like this one so please help me. Thanks in advance.
The bottom of the bust looks like a die crack, the lines in front of the neck are from a clash, and the doubling you are seeing is from die deterioration.
Thank you non_cents. Guess I was on the right track and just needed clarification (die deterioration). I thought die crack at first on the bust but because the line was raised and it looks like the bottom part is just missing a layer made me question die crack vs lamination peel. The entire coin is very shiny considering it's a 1955...so I also thought someone might have dipped/cleaned it which in turn caused the line at the bottom also.
