    I agree. They're strike doubling or "MD" at the hubbing stage. That's all they're detecting on these, really.

    It looks like some doubling in the lettering of LIBERTY. This is a common spot for doubling on the squeezed era coins. I suspect that I have several dozen unattributed DDO/DDR varieties for this era. It's more fun for me when the doubling is more like Rick's specimen, but to each...their own. No judgment.

    Yes. What @expat is referring to has to do with the shape of the rods before they are made into the dies. I'm sure that there are a few resources that describe it in full...probably Wexler's site relative to the class of doubling. From what I recall, the conical rods tend to be susceptible to more doubling at the center when pressed into dies because of their original shape.

    Thank you. I read about it somewhere and for the life of me I could not recall where,

    The reason for a lot of minor doubling towards the centers of the designs from the single squeeze method revolves around the face of the working hub being slightly convex, so the center is slightly raised in relation to the rim gutter.
    As the technician aligns the working hub into place against the working die with a "kiss" there is sometimes a need to reposition the dies. This repositioning can create a slight misalignment between any design elements that may already be on the die from the "kiss" and the actual single squeeze.

    Since the face of the working hub is slightly convex the center design elements are usually what exhibits the doubling.

    Hope I said that correctly and it makes sense for some of the doubling from the single squeeze method of making dies.

    That's most definitely doubling on Liberty.
