Triple Die or MD 0

[Kevin Simpson]

                Seems that there appear to be a number of issues with these new quarters. Can anyone tell me if  this is a triple die or a MD. I'm finding at least in this roll, doubling on a number of coins but I think are MD. This one however has a lot more detail. Any opinions would be appreciated. Sorry for so many questions. I think by your information I can tell the MD at least. I'm still learning however. Thanks again.

Not a Triple Die, It's known as  Triple MD. The Die may have been loose and bounced twice when it was released.

 DD on modern coins happens towards the centre of the coin, not the edges. This due to the introduction of the Single-Squeeze Hubbing introduced in the mid 90's so it is safe to say that (nearly ?) all doubling around the edges is MD.

Once again Greenstang I've learned some very informative information from you. Where I haven't seen this before, I assume that triple MD isn't very common. Again thank you.

I have seen it before but naturally not as much as regular MD
