Philmow New Member United States 19 Posts	Posted 09/27/2017 12:30 am I came across this nickel today with what I presume is some form of Strike Doubling along "Liberty" and the the date. I'm curious if there is a name for this type. I have not come across images quite like it yet, but I'm pretty sure one of you have. Thank you for the input. Report this Post to the Staff

Crazyb0 Rest in Peace 10197 Posts	Posted 09/27/2017 12:47 am Think you're referencing the "lines" running towards the rim? These/are what's called die flow lines. As dies wear, the metal moves outward, the details stretch, become wider. Stresses are placed at the weakest points on the die face which is around the edges of the details(remember its a mirror image, reversed). What you see as the lowest of a letter is actually the die surface. Flow lines are just stressors within the metal, not really a crack, just a pulling . sorry not the most explicit answer, hope you understand. It is a form of Die Deterioration, not a doubling effect or caused by the strike movement. Edited by Crazyb0 09/27/2017 12:53 am Report this Post to the Staff

Since all the lines point outward toward the rim, it must be some form of Die Deterioration, right?

Philmow New Member United States 19 Posts	Posted 09/27/2017 3:45 pm Ok, got it. Die flow from Die Deterioration. And thank you for the Ken Potter link. It is a great resource. I actually reviewed that prior to submitting my forum question but didn't quite see the same looking affect on the examples, so was still unclear to me. I guess that makes sense because it isn't actually a form of doubling. Thank you so much for your helpful responses! Report this Post to the Staff
