Jewelman13 Valued Member United States 50 Posts	Posted 09/01/2015 11:05 am Opened up a fresh roll of 2015 pennies and I have found this. What looks like bubbling under the copper...? I hope the photos help... Report this Post to the Staff

Jewelman13 Valued Member United States 50 Posts	Posted 09/01/2015 11:30 am Is it a mint error or PMD? Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 09/01/2015 11:36 am It is an issue with the plating on the planchet. During the 1980's Zincolns there was an issue with the rinsing of the planchets before the plating. Many coins looked like your coin (and often worse) but very common. It occurs less now. But it is a planchet error, but common. So no premium for these. They actually are less desirable to collectors. Report this Post to the Staff
Atlas642 Pillar of the Community United States 562 Posts	Posted 09/01/2015 11:37 am It's a very common planchet error with little to no value besides being a curiosity. I've heard that very warm climates or zinc rot can do this too, but I don't think that would occur so quickly in a fresh roll. Edited by Atlas642 09/01/2015 5:07 pm Report this Post to the Staff
Pete41 Valued Member United States 261 Posts	Posted 09/01/2015 11:40 am Agree with ATLAS642. They are cool looking though as they are one of the few coin conditions that you can actually see without magnification. Some that I have kept from the early 80's, 82 and after, look like the coin has a case of the measles. Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 09/01/2015 1:46 pm I would not call it a mint error since the Zincoln planchets are prepared by an outside contractor(Jarden Zinc), it is more of a quality control issue that will cause the coin to degrade over time. The term "mint error" typically denotes desirability and collectibility, zinc zits are anything but desirable. The US Mint also makes an effort to segregate errors but things like zinc zits, die cracks, and chips are allowed to enter circulation.
