How can it be a mechanical doubling, nice and flat like all the common mechanical doublings, but still have a raised area around the letters? What I am missing here? There must be something I don't get right. Thank you guys
Sunday, I've never liked this diagram representing mechanical doubling (aka machine doubling) because it suggests that the juncture of the "false doubling" and the letter, number or device is rounded, but actually, it is not. What happens is that the die is loose and vibrates strongly back and forth, and as it retracts from the strike, it shaves a small amount of coin metal from the face of the letter, number or device.

I can see the mechanical. i wrote that down on my title and description. My question is about the, let's say abrasion like? deteriorate like? , die above the letters. Sometimes I look too hard with no reason. Maybe this is one of those cases
Fair enough. It is a good visual representation of doubling though IMO. Your missing clad half is still only worth 50 cents
Never without reason if you are learning something. Chris' explanation of how the metal is sheared off is a good way to look at it.
The analogy I came up with was cutting a cookie with a cookie cutter and just as you start to raise it from the dough, you move it a bit, leaving the "lower shelf".
A couple of tips that helped me were to focus on the corners of the letters. there needs to be notching. Also, true doubling will make the letters bigger whereas mechanical doubling will make the letters smaller if you can imagine that.
