I've been scratching my head for a while looking at this one. I see plating disturbance doubling, but I'm lost with what's going on in the lower front bust area. Is this die deterioration or ejection doubling? Or a split plating problem? Thought I'd post it and ask the experts.

It does appear to be a plating issue also. The zinc under the plating has corroded and turned to dust so the plating is left without any support and begins to buckle.

Thank you both for your replies. I'll probably keep it as a reference!
