Thank you! I know I realized it after. Dang I thought I was getting better with jumping the gun! Lol. But thank you. Appreciate it!
The first few photos look more like a strike through than a grease strike, to me. If it was struck through debris, it would account for only one having the anomaly.
Fred is retired. If it is an abraded die then there are other examples out there, if it is a struck thru then the look will vary.
