Crazyb0 Rest in Peace 10197 Posts	Posted 10/24/2017 10:19 pm What happens a lot of times to the "Zincolns" is plating issues. If any debris is under the thing plating OR upon stamping the plating is torn around the edges like your at the mint mark, a chemical reaction occurs on the zinc, oxidation/corrosion is occurring releasing gasses (bubbles, blisters, lines) or grayish/black powdery corrosion (under or through the open seams. It is almost a perfect "battery with the zinc/copper material, just needs a catalyst (moisture). Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 10/24/2017 10:21 pm When the plating is split from either a strong strike or by damage, then the zinc underneath is exposed. The the oxygen in the air breaks down the zinc. often seen as a gray area or a pothole look on the coin like yours has. The linear plating bubbles are from gas trapped under the plating during the striking. They can be on the fields, or across the devices or both. They can be small of in long lines. Thus the term Linear plating bubble that tends to be in a straight line. Edited by coop 10/24/2017 10:25 pm Report this Post to the Staff
