Depends a lot of things could happen when its in circulation to cause it to be to light or to heavy it could be struck to thick or to light also do you have pictures if its a particular coin.
Call it strike doubling, mechanical doubling or machine doubling but don't call it Doubled die doubling .
No, I was just saying . . I think your coin is in reason. There is a variance in each denomination that coins can be . All the doubling I listed are the same thing . Just different wording for NAV ( No added value ) .
No, it doesn't. It is a simple straightforward question. If you don't know the answer, why comment. No prizes are given to be first to answer.
Attached is a copy of tolerances for various US coinage, so you can see for yourself. As @SensibleSal66 said, there are a few things that can come into play. Your coin is 0.09g over max weight, so not really enough to write home about, a slightly thicker planchet could account for that. As an aside.. When you go to post your pictures, after uploading the image, choose 'Full Image', makes it easier for us old farts to see better and not needing to click on a small picture to try and see what you are showing us.
It helps if you tell us where you think you see it. I really don't see any, but then, I'm really bad at this (full disclosure)
