Tommyjet Valued Member United States 334 Posts	Posted 02/28/2016 4:21 pm Ok I have seen some gas bubbles before on some 80's coins but this takes the cake. What else could this be. Plating issue? Thanks to the members for looking/. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 02/28/2016 4:34 pm Split plating. Small holes in the plating allow for air to reach the zinc underneath and the plating starts to rise. Even a pin hole will start this process of destruction. Report this Post to the Staff
Rackster Pillar of the Community United States 4809 Posts	Posted 02/28/2016 4:37 pm I had a similar 87D earlier today. I could see clear past the plating to the void below. Once the copper splits, the substrate (zinc) is subject to the elements. Eventually, hydrozincite sets in (under magnification, it looks like bright white cauliflower). Since the zinc is consumed, the void is left and the copper collapses in. Report this Post to the Staff
