Look at his sideburns and facial area. If it is from multiple off center strikes, why aren't other areas like that and it is just the side of his face?
I do see a little of what you are seeing but, I think it is just from the planchet expanding beyond the collar.
So I'm just talking off the cuff, but I think that's a single broadstrike and the metal flows make it appear as though the images are doubled. Here's my broadstrike for reference.
I believe Mike Diamond calls this 'split-line doubling' from striking pressure, and there being no collar to 'hold' the coin, so the copper plating splits apart/off the surface of the coin.
Very nice error but don't stare at it too long. It will make your eyes water. @JCro57 Just where do you find all of these neat errors that you've been posting lately?
I may be way off base here, but I agree with Fred, and here's how I think it happens, not an expert like Fred, so bear with me: The die initially hits the planchet and creates the "doubling" of the bust...then the rest of the pressure of the strike completes itself on the un-collared coin, creating the central design. Makes sense logistically, imo, but this seems to cover what Fred said too...Spark
I know about split plating. I am talking about what looks like raised metal from other strikes. I should get a better idea in hand
