datadragon Pillar of the Community United States 1648 Posts	Posted 07/27/2022 07:28 am Hmmm. a powdery, white, opaque substance can be from a protective layer of zinc bloom or Hydrozincite that has formed over a original split in the plating on the newer 1982+ Lincoln cents. When zinc is exposed to the atmosphere (carbon dioxide), it quickly tarnishes and forms a passivating layer of zinc bloom or Hydrozincite (zinc carbonate). This layer helps prevent further deterioration of the zinc.The splitting of the copper plating on post 1981 Lincoln cents usually led to an exposed zinc core which in turn formed this protective layer. If that coin went into circulation, the normal use would cause that protective layer to be removed and a process of reformation would begin anew. The continuous handling of the coin would have a recurrence of these events, but with an increasing size of the affected area. It is post strike mint damage https://www.error-ref.com/zinc-dete...ncoln-cents/ Edited by datadragon 07/27/2022 07:31 am Report this Post to the Staff
Dearborn Moderator United States 95460 Posts	Posted 07/27/2022 1:03 pm It does look like it was a 1989 zinc cent to me too. Acid? possible, or something very caustic affected this coin.
