Fuzzy317 Moderator United States 14463 Posts	Posted 02/03/2017 11:39 pm many recent Lincoln Cents, lovingly referred to as Zincolns, have this problem. When a pin hole allows air to reach the zinc core, it starts a process called zinc rot. This causes gas bubbles to form under the zinc plating. Report this Post to the Staff
cwb Pillar of the Community United States 3463 Posts	Posted 02/04/2017 05:54 am Does it look like this one? Quote: This was caused by problems with the plating process and is most common on cents minted in the 1980's, but can be found on any cent minted after 1982 when Copper plating was first used. Gas bubbles would become trapped beneath the Copper plating and cause these raised areas. They seem to be more common on cents from the Denver mint. Solid-alloy cents minted in 1982 and earlier can have occluded gas bubbles caused from heat generated when a planchet is struck. The expanding gas pushes a layer of metal towards the surface of the coin, resulting in a raised area or bubble. Occluded gas bubbles are much rarer than the blistered plating found on newer cents. http://lincolncentsonline.com/miscellaneous.html Report this Post to the Staff

albertharris Pillar of the Community United States 901 Posts	Posted 02/04/2017 10:09 am What year is the penny. Most 1983 to present are copper coated zinc. These zincoln's are relatively common with plating issues. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 02/04/2017 10:10 am There was an issue with a poor rinse process with the original Zincolns when they didn't get the dust off the planchets. Also there was an issue with gas under the plating leaving bubble. You have examples of both on your coin. There is no premium for this In fact the opposite. If you saw this on a variety coin you did want, I would pass on them. Get the best example you could get, without the issues. You will get a better price for them in when do sell them.
