    On the bottom serif of the G in Chicago, it's not straight - is it just PMD that skews it in the wrong direction? Also, on the 1892 date, the 9 looks to be doubled, but that may just be die deterioration. Thanks in advance for your thoughts and verification.

    Thanks for that example, Paddy54. I can see how MD tends to have a "flat" doubling off to one side. After further reading what's on the Wexler site, I guess I'm just generally confused with MD, though the tell tale signs are very clear (e.g. flat doubling, not raised and rounded doubling, etc.). The confusing bit is that if it's MD caused by loose die parts when pressing the coins together, why is it usually just the letters/numbers/MM, and not the entirety of the coin (e.g. the portrait and rest of the design features)? For example, on Wexler's site they have this image below which is MD on the portrait of Kennedy. Why don't most MD coins have that doubling on the portrait? Isn't it two solid dies sandwiching a planchet, and when it's a loose die(s), the ENTIRE planchet should show shifts on every single design element most of the time?

    GOTCHA :blackeye:
    I just want the members here to know that Frank aka" the other Frank" is truly a nice person. Sort of like your Grandfather .....yeah he's grumpy at times,and you got to keep reminding him it's not cool to take his teeth out at parties.
    But really he so nice .....well here's an example . ....in Chicago at the world fair of money he once shared his lunch with a squirrel .
    So I ask you....if your willing to share your twinkle with a tree rat ....how nice is that?:beaver:

    I'm not quite sure how it happens other than a shifting takes place. I've seen it a lot on double profiles on Jefferson nickels as well as Bust half dollars . It is funny that one some series it seems to happen more than others.
    I still like searching and even finding these ,as one never knows what you may find.

    Like on this 2014 Silver Eagle... there is clearly some sort of doubling on the inside of the A in DOLLAR, but nothing on the insides of any other letter like the R (scratches are on air-tite). Unless this is a double die... shifts in the die don't make other letters doubled except in that one area? This one is not as obvious and doesn't seem to be as flat of a doubling, so actually, I'm not sure that this one is MD... any thoughts?
