Just imagine you were a planchet. To become a coin you spent a fraction of a split-second of your life sandwiched in between two heavy dies that tried to squish you flat as a pancake at the rate of machine gun fire and then ejected you into a big holding tub. What you’re seeing on that reverse is just the natural consequence of any movement or shaking, ever so slight, at that precise moment of strike. As such, it’s called “strike doubling,” and it’s pretty common. Sorry about that. But keep fishing.
Oh no, yours is vastly different than that. Look at the oF AM closeups in the MDS marker photos, it's pretty obvious, there. Yours just looks like the result of a slight "slide" or "jerk" leaving the secondary images. IMHO. Take a look.
That is correct. It's just strike doubling but you will find a true doublED die at some point. Really look at the two, the real DDR (photo) and your coin then set them down and look at them tomorrow - keep looking until you really see the difference - the difference is the real doublED die reverse is thick, slightly over lapping, juxtapositioned from the primary letters and is not scooted - that's what you want to learn.
