The extended markings between rim and lettering on UNITED STATES OF AMERICA on obverse and HAWAII on reverse. What caused this?
I'm not up on these types of things so I posted the link. Not sure at all what you have there and I'm hoping someone will chime in when they see this 'chatter'. In other words.......Bump!
Current thoughts: 1)caused during ejection 2)something akin to R.R.D.D. 3) improperly prepared planchet. Come on folks, take a stab!
Thanks Jay, I'll keep that as the front - runner as I have no clue and no one else sems to be able to add to it.
