JohnDeVito Valued Member United States 196 Posts	Posted 12/23/2015 10:04 am I thought for a split second that this was doubled in some form, but then I figured it must be some sort of damage. The picture doesn't portray it very well. I am having a hard time showing it, but the silvery parts above the letters (especially the TED in UNITED and both S in STATES) are raised. I am wondering what you all think. Thanks, John Report this Post to the Staff

Conder101 Bedrock of the Community United States 17884 Posts	Posted 12/23/2015 10:24 am The "silver" parts above the letters is exposed zinc where the plating split at the tops of the letters during the strike and then was carried away from the letters by the stretching/expansopn of the planchet during the strike. They should not be raised, but if they are it is probably from the formation of zinc oxide(zinc rot) from the exposure of the zinc to the air and moisture. Report this Post to the Staff

jjwabraham Valued Member United States 288 Posts	Posted 12/23/2015 5:23 pm I'm thinking it is a double-struck along that edge, possibly the edge of the die struck slightly closer to the edge of the planchet, then when the coin was actually fully struck it was slightly lower and the "TED" of UNITED, all of STATES, "F" of OF, and "E" and "C" of AMERICA all show "ghosts" from the first strike above them. Does anyone else see that? Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 12/23/2015 5:36 pm The "ghosts" are just the split plating from a single strike, this is a very common phenomenon on 1980s and 1990s Zincolns. Report this Post to the Staff
