ChildOfTheWheat Pillar of the Community United States 5828 Posts	Posted 09/13/2015 08:46 am Ah, a classic case of Split Plate Doubling! Not rare or valuable, quite common on zinclons. Report this Post to the Staff
Rackster Pillar of the Community United States 4809 Posts	Posted 09/13/2015 10:55 am Looks like split plating on the upper portion of the devices perhaps (near the rim) and machine damage at the bottoms of the devices. As tweak notes, you'll see many of these CRH. And you'll see a few different stages. Just MD, and where the copper plate has been compromised, the zinc it subject to the air and deterioration (hydrozincite will form). Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 09/13/2015 11:12 am I agree split plating is the cause. Sometimes it is mild, other times strong. Just depends on the extreme strike pressure. No premium for these as the long term effects will show a breakdown of the zinc. Report this Post to the Staff
